	BASIS OF PREPARATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Business
	Oclaro, Inc., a Delaware corporation, is sometimes referred to in this Annual Report on Form 10-K as “Oclaro,” “we,” “us,” or “our.”
	During our fiscal year 2014, we were one of the leading providers of optical components, modules and subsystems for the core optical transport, service provider, wireless backhaul, enterprise and data center markets. Leveraging over three decades of laser technology innovation, photonic integration, and subsystem design, we provide differentiated solutions for optical networks and high-speed interconnects driving the next wave of streaming video, cloud computing, voice over IP, Software as a Service ("SaaS") and other bandwidth-intensive and high-speed applications.
	On November 1, 2013, we sold our optical amplifier and micro-optics business (the “Amplifier Business”) to II-VI Incorporated (II-VI). The sale is more fully discussed in Note 3, Business Combinations and Dispositions.
	On September 12, 2013, we sold our Oclaro Switzerland GmbH subsidiary and associated laser diodes and pump business (the “Zurich Business”) to II-VI. The sale is more fully discussed in Note 3, Business Combinations and Dispositions.
	These sales are reported as discontinued operations, which require retrospective restatement of prior periods to classify the assets, liabilities and results of operations as discontinued operations. We have classified the assets and liabilities to be sold as “assets of discontinued operations held for sale” and “liabilities of discontinued operations held for sale” within current assets and current liabilities, respectively, on the consolidated balance sheet as of June 29, 2013. The notes to our consolidated financial statements relate to our continuing operations only, unless otherwise indicated.
	On July 23, 2012, we completed a merger with Opnext, Inc. ("Opnext"). The acquisition is more fully discussed in Note 3, Business Combinations and Dispositions. The consolidated balance sheets as of June 28, 2014 and June 29, 2013, include the assets and liabilities assumed in the Opnext acquisition. The consolidated statements of operations, comprehensive income (loss) and cash flows for the years ended June 28, 2014 and June 29, 2013 include the results of operations of the combined entities from July 23, 2012, the date of the acquisition. Our statements of operations, comprehensive income (loss) and cash flows for the year ended June 30, 2012, do not include any results of operations from Opnext.
	Basis of Preparation
	The consolidated financial statements include the accounts of Oclaro and our subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), which contemplate the continuation of a company as a going concern. As of June 28, 2014, we held $104.1 million in cash and short-term investments, comprised of $99.0 million in cash and cash equivalents, $5.1 million in restricted cash and $0.1 million of short-term investments; and we had working capital of $175.2 million. We have incurred significant operating losses from continuing operations and generated negative cash flows from operations for fiscal year 2014. Recoverability of a major portion of the recorded asset amounts shown in the accompanying balance sheet is dependent upon us having sufficient resources to operate our business. In addition to the availability of our cash resources as of June 28, 2014, the continued operation of our business is dependent upon our achieving cash flows expected to be generated from the execution of our current operating plan, including anticipated restructuring plans, together with amounts expected to be available under our Credit Agreement and from the sale of our Komoro, Japan industrial and consumer business. See Note 17, Subsequent Events for further details on the sale of our Komoro, Japan industrial and consumer business. We can make no assurances that we will be successful concluding the sale of our Komoro, Japan industrial and consumer business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should we be unable to continue in existence.
	In the event that any of the sources of liquidity described in the preceding paragraph are, for any reason, not available to us in a timely manner or in the event that we need additional liquidity beyond our current expectations, such as to fund future growth or strengthen our balance sheet or to fund the cost of restructuring activities, we may find it necessary to lower our operating income break-even level and undertake additional cost cutting measures. We will continue to explore other sources of additional liquidity. These additional sources of liquidity could include one, or a combination, of the following: (i) issuing equity securities, (ii) incurring indebtedness secured by our assets, (iii) issuing debt and/or convertible debt securities, or (iv) selling product lines, other assets and/or portions of our business. There can be no guarantee that we will be able to raise additional funds on terms acceptable to us, or at all.
	Reclassifications
	For presentation purposes, we have reclassified certain prior period amounts to conform to the current period financial statement presentation. These reclassifications did not affect our consolidated net income (loss), cash flows, cash and cash equivalents or stockholders’ equity as previously reported.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reported periods. Examples of significant estimates and assumptions made by management involve the fair value of goodwill and long-lived assets, the fair value of purchase consideration paid, assets acquired and liabilities assumed in business combinations, valuation allowances for deferred tax assets, the fair value of stock-based compensation, estimates used to determine facility lease loss liabilities, estimates for allowances for doubtful accounts, the evaluation of insurance recoveries, and valuation of excess and obsolete inventories. These judgments can be subjective and complex and consequently actual results could differ materially from those estimates and assumptions.
	Out of Period Adjustment
	In fiscal 2014, we recorded an out-of-period adjustment of approximately $2.0 million in flood-related (income) expense in our consolidated statements of operations. The adjustment, which decreased flood-related income and decreased property and equipment, net, was made to account for the impairment of leased assets assumed pursuant to the Opnext merger that had been damaged in the 2011 Thailand flood (see Note 6, Flood-Related (Income) Expense, Net). We determined that this adjustment did not have a material impact to our current or prior period consolidated financial statements.
	Fiscal Years
	We operate on a 52/53 week year ending on the Saturday closest to June 30. Our fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012 were each 52 week years.
	Cash and Cash Equivalents
	Cash and cash equivalents are carried at market value. We consider all liquid investment securities with an original maturity date of three months or less to be cash equivalents. Any realized gains and losses on liquid investment securities are included in other income (expense) in our consolidated statements of operations.
	The following table provides details regarding our cash and cash equivalents at the dates indicated:
		June 28, 2014			June 29, 2013
		(Thousands)
	Cash and cash equivalents:
	Cash-in-bank	$	97,759		$	82,634
	Money market funds	1,214			2,001
		$	98,973		$	84,635
	As of June 28, 2014, $74.7 million of the $99.0 million of our cash and cash equivalents was held by our foreign subsidiaries. If these funds are needed for our operations in the United States, we could be required to accrue and pay U.S. taxes to repatriate these funds (subject to an adjustment for foreign tax credits).
	As of June 28, 2014, we also had restricted cash of $5.1 million, consisting of approximately $2.6 million which serves as collateral for the performance of our obligations under certain facility lease agreements and $2.4 million (equivalent to RMB 15 million) of cash held in Oclaro Shenzhen’s bank account in China that was frozen by the Xi'an Court in connection with our litigation with Xi’an Raysung Photonics Inc. (see Note 9, Commitments and Contingencies, for additional details regarding this litigation.)
	Concentration of Credit Risks
	We place our cash and cash equivalents with and in the custody of financial institutions, which at times, are in excess of amounts insured. Management monitors the ongoing creditworthiness of these institutions. Our investment policy limits the amounts invested with any one institution, type of security and issuer. To date, we have not experienced significant losses on these investments.
	Our trade accounts receivable are concentrated with companies in the telecom industry. At June 28, 2014, three customers accounted for a total of 42 percent of our gross accounts receivable. At June 29, 2013, three customers accounted for a total of 33 percent of our gross accounts receivable.
	Allowance for Doubtful Accounts and Sales Return Allowance
	We perform ongoing credit evaluations of our customers and record specific allowances for doubtful accounts when a customer is unable to meet its financial obligations, as in the case of bankruptcy filings or deteriorated financial position. Estimates are used in determining allowances for customers based on factors such as current trends, the length of time the receivables are past due and historical collection experience. We write-off a receivable account when all rights, remedies and recourses against the account and its principals are exhausted and record a benefit when previously reserved accounts are collected. We recorded minimal provisions as allowances for doubtful accounts in fiscal year 2014 and $0.7 million and $0.1 million as allowances for doubtful accounts in fiscal years 2013 and 2012, respectively.
	We record a provision for estimated sales returns, which is netted against revenues, in the same period as the related revenues are recorded. These estimates are based on historical sales returns, other known factors and our return policy. In fiscal year 2014, 2013 and 2012, we recorded a provision of zero, $3.1 million and zero as sales return allowances, respectively.
	Inventories
	Inventories, consisting of raw materials, work-in-process and finished goods are stated at the lower of cost (first in, first out basis) or market. We plan production based on orders received and a forecast demand. These production estimates are dependent on assessment of current and expected orders from our customers, including consideration that orders are subject to cancellation with limited advance notice prior to shipment. We assess the valuation of our inventory, including significant inventories held by contract manufacturers on our behalf, on a quarterly basis. Products may be unsalable because they are technically obsolete due to substitute products, specification changes or excess inventory relative to customer forecasts. We adjust the carrying value of inventory using methods that take these factors into account. If we find that the cost basis of our inventory is greater than the current market value, we write the inventory down to the estimated selling price, less the estimated costs to complete and sell the product.
	The following table provides details regarding our inventories at the dates indicated:
		June 28, 2014			June 29, 2013
		(Thousands)
	Inventories:
	Raw materials	$	20,036		$	32,678
	Work-in-process	20,505			26,760
	Finished goods	30,558			26,591
		$	71,099		$	86,029
	Property and Equipment
	Property and equipment are stated at cost. Depreciation is computed using the straight-line method based upon the estimated useful lives of the assets, which generally range from three to seven years. Leasehold improvements are amortized using the straight-line method over the estimated useful lives or the term of the related lease, whichever is shorter. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are removed from the accounts. Gains or losses resulting from asset dispositions are included in (gain) loss on sale of property and equipment in the accompanying consolidated statements of operations. Repair and maintenance costs are expensed as incurred.
	The following table provides details regarding our property and equipment, net at the dates indicated:
		June 28, 2014			June 29, 2013
		(Thousands)
	Property and equipment, net:
	Buildings and improvements	$	12,989		$	10,271
	Plant and machinery	47,247			72,144
	Fixtures, fittings and equipment	9,701			4,295
	Computer equipment	13,723			13,940
		83,660			100,650
	Less: accumulated depreciation	(32,892		)	(28,622		)
		$	50,768		$	72,028
	Depreciation expense was $25.3 million, $30.0 million and $12.9 million for the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, respectively. In fiscal year 2014, we recorded an impairment charge of $0.6 million related to the write-off of certain machinery that was not being utilized.
	Property and equipment includes assets under capital leases of $9.9 million and $18.2 million at June 28, 2014 and June 29, 2013, respectively, the majority of which were assumed in connection with the Opnext acquisition. Amortization associated with assets under capital leases is recorded in depreciation expense.
	Goodwill and Other Intangible Assets
We review our goodwill and other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable and also review goodwill annually. The values assigned to goodwill and other intangible assets are based on estimates and judgments regarding expectations for the success and life cycle of products and technologies acquired.
In fiscal year 2013, our goodwill was tested for impairment using a two-step process. In the first step, the estimated fair value of a reporting unit is compared to its carrying value. If the fair value of a reporting unit exceeds the carrying value of the net assets assigned to a reporting unit, goodwill is considered not impaired and no further testing is required. If the carrying value of the net assets assigned to a reporting unit exceeds the fair value of a reporting unit, a second step of the impairment test is performed whereby we hypothetically apply purchase accounting to the reporting unit using the fair value from the first step in order to determine the implied fair value of a reporting unit’s goodwill. We estimate the fair value of the reporting unit using the expected present value of future cash flows and also compare our market capitalization plus a control premium for reasonableness. See Note 4. Goodwill and Other Intangible Assets.
In fiscal year 2013, we adopted the Financial Accounting Standard Board's ("FASB") Accounting Standards Update ("ASU") 2012-2, Intangibles—Goodwill and Other (Topic 350)—Testing Indefinite-Lived Intangible Assets for Impairment, which established an optional two-step analysis for impairment testing of indefinite-lived intangibles other than goodwill. The two-step analysis establishes an optional qualitative assessment to precede our quantitative assessment, if necessary. In the qualitative assessment, we must evaluate the totality of qualitative factors, including any recent fair value measurements, that impact whether our indefinite-lived intangibles other than goodwill have a carrying amount that more likely than not exceeds their fair value.
Impairment of Long-Lived Assets
We review property and equipment and certain identifiable intangibles, excluding goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparing their carrying amounts to market prices or the future undiscounted cash flows the assets are expected to generate. If property and equipment or certain identifiable intangibles are considered to be impaired, the impairment to be recognized would equal the amount by which the carrying value of the asset exceeds its fair value based on market prices or future discounted cash flows.
Intangible assets with definite lives are amortized over their estimated useful lives, which is generally from 1 to 11.5 years and 15 years as to one specific customer contract.
Non-Marketable Cost Method Investments
We account for our non-marketable cost method investments, which consist of less than 20 percent equity ownership interests of common stock and/or preferred stock in privately-held companies, under the cost method of accounting. As of June 28, 2014 and June 29, 2013, we no longer held any investments in privately-held companies. During fiscal year 2013, we sold our remaining cost method investment for $3.9 million of cash proceeds. We had previously acquired this investment in fiscal year 2010 for a purchase price of $7.5 million. We recorded a $3.6 million impairment charge during fiscal year 2013 in other income (expense) in our consolidated statement of operations.
Derivative Financial Instruments
Our operating results are subject to fluctuations based upon changes in the exchange rates between the currencies in which we collect revenues and pay expenses. A majority of our revenues are denominated in U.S. dollars, while a significant portion of our expenses are denominated in United Kingdom (U.K.) pounds sterling, Japanese yen, Chinese yuan and euros, in which we pay expenses in connection with operating our facilities in the United Kingdom, Japan, China and Italy. Prior to our sale of our Zurich Business, we also incurred a significant portion of our expenses in Swiss francs. Historically, we have entered into foreign currency forward exchange contracts in an effort to mitigate a portion of our exposure to exchange rate fluctuations between the U.S. dollar and the U.K. pound sterling.
We recognize all derivatives, such as foreign currency forward exchange contracts, on our consolidated balance sheets at fair value regardless of the purpose for holding the instrument. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through operating results or recognized in accumulated other comprehensive income until the hedged item is recognized in operating results in our consolidated statements of operations.
At June 28, 2014 and June 29, 2013, we had no outstanding foreign currency forward exchange contracts.
Accrued Expenses and Other Liabilities
The following table provides details for our accrued expenses and other liabilities at the dates indicated:
	June 28, 2014			June 29, 2013
	(Thousands)
Accrued expenses and other liabilities:
Trade payables	$	18,612		$	10,391
Compensation and benefits related accruals	10,242			13,117
Warranty accrual	4,672			4,670
Accrued restructuring, current	2,220			5,363
Other accruals	15,746			18,469
	$	51,492		$	52,010
Warranty
We generally provide a warranty for our products ranging from 12 months to 36 months from the date of sale, although warranties for certain of our products may be longer. We accrue for the estimated costs to provide warranty services at the time revenue is recognized. Our estimate of costs to service our warranty obligations is based on historical experience and expectation of future conditions. To the extent we experience increased warranty claim activity or increased costs associated with servicing those claims, our warranty costs would increase, resulting in a decrease in gross profit.
Revenue Recognition
We recognize product revenue when (i) persuasive evidence of an arrangement exists, (ii) the product has been shipped and title has transferred, (iii) collectability is reasonably assured, (iv) the fees are fixed or determinable and (v) there are no uncertainties with respect to customer acceptance. We record a provision for estimated sales returns in the same period as the related revenues are recorded, which is netted against revenue. These estimates are based on historical sales returns, other known factors and our return policy.
Research and Development Costs
Research and development costs are expensed as incurred.
Advertising Costs
Advertising costs are expensed as incurred. Our advertising costs for the years ended June 28, 2014, June 29, 2013 and June 30, 2012 were not significant.
Restructuring Expenses
We record costs associated with employee terminations and other exit activities when the liability is incurred. Employee termination benefits are recorded when the benefit arrangement is communicated to the employee and no significant future services are required. If employees are required to render service until they are terminated in order to receive the termination benefits, the fair value of the termination date liability is recognized ratably over the future service period. Lease cancellation and commitment costs are recorded when we cease using the facility. Lease cancellation and commitment costs are calculated using estimated future lease commitments less estimated sublease income, based on current market conditions. See Note 5, Restructuring Liabilities.
Insurance Recoveries
Insurance recoveries related to impairment losses previously recorded and other recoverable expenses will be recognized up to the amount of our related loss or expense in the period that recoveries become realizable. Insurance recoveries under business interruption coverage and insurance recovery gains in excess of amounts previously written off related to impaired inventory and equipment or in excess of other recoverable expenses previously recognized will be recognized when they become realizable and all contingencies have been resolved.
During the year ended June 28, 2014 and June 29, 2013, we received $3.7 million and $30.8 million in settlement payments, respectively, relating to losses we incurred due to flooding at our contract manufacturer in Thailand. As there were no contingencies associated with these payments, we recorded these payments within flood-related (income) expense, net in our consolidated statements of operations for the year ended June 28, 2014 and June 29, 2013, respectively.
The evaluation of insurance recoveries requires estimates and judgments about future results which affect reported amounts and certain disclosures. Actual results could differ from those estimates.
Stock-Based Compensation
We use the Black-Scholes option pricing model to value the fair value of stock options, purchase rights under our employee stock purchase program and stock appreciation rights. We use grant date fair value to value restricted stock awards, restricted stock units and performance shares.
We record compensation expense using the straight-line method and estimate forfeitures when recognizing compensation expense, and we adjust our estimate of forfeitures over the requisite service period based on the extent to which actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of compensation expense to be recognized in future periods. The amount of stock-based compensation expense recognized in any one period related to performance shares can vary based on the achievement or anticipated achievement of the performance conditions. If the performance conditions are not met or not expected to be met, no compensation cost would be recognized on the underlying performance shares, and any previously recognized compensation expense related to those performance shares would be reversed.
Stock options have a term of seven to ten years and generally vest over a two to four year service period, and restricted stock awards generally vest over a one to four year service period, and in certain cases each may vest earlier based upon the achievement of specific performance-based objectives as set by our board of directors or may be subject to additional vesting conditions based upon achievement of such performance-based objectives.
Foreign Currency Transactions and Translation Gains and Losses
The assets and liabilities of our foreign operations are translated from their respective functional (local) currencies into U.S. dollars at the rates in effect at the consolidated balance sheet dates, and revenue and expense amounts are translated at the average rate during the applicable periods reflected on the consolidated statements of operations. Foreign currency translation adjustments are recorded as accumulated other comprehensive income, except for the translation adjustment of short-term intercompany loans or payables which are recorded as gain (loss) on foreign currency transactions in our consolidated statements of operations. Gains and losses from foreign currency transactions, realized and unrealized in the event of foreign currency transactions not designated as hedges, and those transactions denominated in currencies other than our functional currency, are recorded as gain (loss) on foreign currency transactions in our consolidated statements of operations.
Income Taxes
We account for income taxes using an asset and liability based approach. Deferred income tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. Valuation allowances are provided against deferred income tax assets which are not likely to be realized.
Net Income (Loss) Per Share
Basic net income (loss) per share is computed using only the weighted-average number of shares of common stock outstanding for the applicable period, while diluted net income (loss) per share is computed assuming conversion of all potentially dilutive securities, such as stock options, stock appreciation rights, unvested restricted stock awards, warrants, shares issuable in connection with convertible notes and obligations under escrow agreements during such period. For the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, we excluded such dilutive securities from the computation of diluted shares outstanding since we incurred a net loss from continuing operations in these periods and their inclusion would have an anti-dilutive effect.
Recent Accounting Pronouncements
In March 2013, the FASB issued ASU No. 2013-5, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. This guidance amends a parent company’s accounting for the cumulative translation adjustment recorded in accumulated other comprehensive income associated with a foreign entity. The amendment requires a parent to release into net income the cumulative translation adjustment related to its investment in a foreign entity when it either sells a part or all of its investment, or no longer holds a controlling financial interest in a subsidiary or group of assets within a foreign entity. We elected to early adopt this guidance during our first quarter of fiscal year 2014. Accordingly, we treated our sale of our Zurich Business in the first quarter of fiscal year 2014 in accordance with this guidance and recorded $3.1 million in income from discontinued operations related to the cumulative translation adjustment from deconsolidating our Swiss subsidiary during the year ended June 28, 2014 within the consolidated statement of operations. This guidance will continue to impact our financial position and results of operations prospectively in the instance of an event or transaction described above.
In July 2013, the FASB issued amended guidance that resolves the diversity in practice for the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This new accounting guidance requires the netting of unrecognized tax benefits ("UTBs") against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. Under the new standard, UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. The new standard requires prospective adoption but allows retrospective adoption for all periods presented. We have adopted this guidance during our second quarter of fiscal year 2014. The adoption of the guidance did not have a significant impact on our financial position, results of operations or cash flows.
In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This update requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity's financial results or a business activity classified as held for sale should be reported as discontinued operations. The standard also expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not meet the definition of a discontinued operation. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2014. This guidance is effective for us prospectively in the third quarter of fiscal year 2015. We do not expect these changes to have a material impact on our consolidated financial statements.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The FASB issued ASU 2014-09 to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016. This guidance is effective for us prospectively in the first quarter of fiscal year 2018. We are currently evaluating the impact that the implementation of this standard will have on our financial statements.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	FAIR VALUE
	We define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. We apply the following fair value hierarchy, which ranks the quality and reliability of the information used to determine fair values:
	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	Level 2 – Inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices of identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets), or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 – Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.
	Our cash equivalents and marketable securities are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include most marketable securities and money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy.
	The contingent obligation related to the make-whole premium on our convertible notes was valued using a valuation model which estimated the value based on the probability and timing of conversion. The contingent obligation was previously classified within Level 3 of the fair value hierarchy. During the second quarter of fiscal year 2014, the holders of the convertible notes exercised their rights to exchange the convertible notes for common stock, and settled the make-whole premium.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Assets and liabilities measured at fair value on a recurring basis are shown in the table below by their corresponding balance sheet captions and consisted of the following types of instruments at June 28, 2014:

	BUSINESS COMBINATIONS AND DISPOSITIONS
	During the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, we recorded $7.8 million, $3.7 million and $2.6 million, respectively, in legal and other direct acquisition-related costs in connection with business combinations and asset dispositions. These costs are recorded within restructuring, acquisition and related (income) expense, net in our consolidated statements of operations.
	Sale of Amplifier Business
	On October 10, 2013, Oclaro Technology Limited entered into an Asset Purchase Agreement with II-VI, whereby Oclaro Technology Limited agreed to sell to II-VI and certain of its affiliates its Amplifier Business for $88.6 million in cash. The transaction closed on November 1, 2013. Consideration, valued at $88.6 million consisting of $79.6 million in cash, which was received on November 1, 2013, $4.0 million subject to hold-back by II-VI until December 31, 2014 to address any post-closing claims and $5.0 million related to an exclusive option, which was received on September 12, 2013 and was credited against the purchase price upon closing of the sale.
	We entered into certain transition service and manufacturing service agreements to allow the Amplifier Business to continue operations during the ownership transition. Both parties provided customary and reciprocal representations, warranties and covenants in the Asset Purchase Agreement.
	We classified the sale of our Amplifier Business as a discontinued operation as of September 12, 2013, the date management committed to sell the business. In connection with this transaction, we transferred $16.2 million in net assets to II-VI. We also incurred approximately $3.0 million in legal fees, commissions and other administrative costs related to this transaction. We recognized a gain of $68.9 million on the sale of the Amplifier Business, which is recorded within discontinued operations in the consolidated statements of operations for the year ended June 28, 2014. As of June 28, 2014, we had a $4.0 million receivable in prepaid expenses and other current assets from II-VI related to the hold-back for potential post-closing adjustments or claims.
	The assets of the discontinued operation are presented as current assets under the caption assets of discontinued operations held for sale in the accompanying consolidated balance sheet at June 29, 2013, and consist of the following:

	Sale of Zurich Business
	On September 12, 2013, we completed a share and asset purchase agreement with II-VI, pursuant to which we sold our Oclaro Switzerland GmbH subsidiary and associated laser diodes and pump business to II-VI. We received proceeds of $90.6 million in cash on September 12, 2013, and $2.9 million in cash during the third quarter of fiscal year 2014 which related to a final settlement of the post-closing working capital adjustment. We will also receive an additional $6.0 million subject to hold-back by II-VI until December 31, 2014 to address any post-closing adjustments or claims. In addition, we retained approximately $14.7 million in accounts receivable related to the Zurich Business and approximately $9.6 million of supplier and employee related payables related to the Zurich Business which were not included in the Zurich subsidiary.
	As part of the agreement, II-VI purchased our Swiss subsidiary, which includes its GaAs fabrication facility, and also the corresponding high power laser diodes, VCSEL and 980 nm pump laser product lines, including intellectual property, inventory, equipment and a related research and development facility in Tucson, all of which are associated with the business. Also, as part of the agreement, II-VI purchased certain pieces of equipment which are located in our Caswell facility. We continue to operate this equipment on behalf of II-VI, and provide certain wafer processing services in Caswell as part of an ongoing manufacturing services agreement.
	As part of the transition services agreement, during fiscal year 2014, we temporarily supplied II-VI with back-end manufacturing of the 980 nm pump and certain high power laser diode products from our Shenzhen, China manufacturing facility. In addition, various supply and transition service agreements have been established between the companies to ensure a smooth transition.
	We have classified the sale of our Zurich Business as a discontinued operation. In connection with this transaction, we transferred $31.4 million in net assets to II-VI and incurred approximately $4.8 million in legal fees, commissions and other administrative costs. We recognized a gain of $63.2 million on the sale of the Zurich Business, which was included in income (loss) from discontinued operations, net of tax, for the year ended June 28, 2014 in our consolidated statements of operations.
	During fiscal year 2014, in connection with the sale of the Zurich Business, we also recorded $3.1 million in income from discontinued operations related to the release of the cumulative translation adjustment from deconsolidating our Swiss subsidiary and a $4.8 million loss from discontinued operations related to the interest charges incurred in connection with the settlement of the term loan (refer to Note 7, Credit Line and Notes for further details.)
	As of June 28, 2014, we recorded a $6.0 million receivable in prepaid expenses and other current assets from II-VI related to the hold-back for potential post-closing adjustments or claims.
	The assets and liabilities of the discontinued operation are presented as current assets and current liabilities, separately under the captions assets of discontinued operations held for sale and liabilities of discontinued operations held for sale in the accompanying consolidated balance sheet at June 29, 2013, and consist of the following:

Sale of Thin Film Filter Business and Interleaver Product Line
On November 19, 2012, we entered into an asset purchase agreement with II-VI Incorporated, Photop Technologies, Inc. and Photop Koncent, Inc. (FuZhou), both wholly owned subsidiaries of II-VI Incorporated, pursuant to which we sold substantially all of the assets of our thin film filter business and our interleaver product line. The transactions closed on December 3, 2012.
The total purchase price under the asset purchase agreement was $27.0 million in cash. During fiscal year 2013, we received $26.0 million in cash proceeds and the remaining $1.0 million during fiscal year 2014.
Under the asset purchase agreement, we made certain customary representations and warranties regarding our thin film filter business and interleaver product line, and we are subject to customary indemnification obligations related to pre-closing liabilities and breaches of representations, warranties and covenants. Also pursuant to the asset purchase agreement, we have agreed not to compete in the thin film filter or interleaver business for a period of five years, subject to certain limitations and exceptions.
In connection with these transactions, we transferred $0.9 million of property, plant and equipment at net book value, $0.7 million of inventory and $0.2 million of other net assets. We also incurred approximately $0.4 million in legal fees, commissions and other administrative costs related to the transactions. We recognized a gain of $24.8 million under the asset purchase agreement within restructuring, acquisition and related (income) expense, net in the consolidated statements of operations for the year ended June 29, 2013.
Acquisition of Opnext
On March 26, 2012, we entered into an Agreement and Plan of Merger and Reorganization, by and among Opnext, Tahoe Acquisition Sub, Inc., a newly formed wholly-owned subsidiary of Oclaro (Merger Sub), and Oclaro, pursuant to which we acquired Opnext through a merger of Merger Sub with and into Opnext. On July 23, 2012, we consummated the acquisition following approval by the stockholders of both companies.
As a result of the acquisition, we converted each issued and outstanding share of Opnext common stock into the right to receive 0.42 of a share of our common stock, par value $0.01 per share (and cash in lieu of fractional shares). In addition, each Opnext stock option that was outstanding and unexercised immediately prior to the acquisition was converted into an option to purchase our common stock (adjusted to give effect to the exchange ratio); and each Opnext stock appreciation right that was outstanding and that remained unsettled immediately prior to the acquisition was converted into either a stock appreciation right with respect to our common stock (adjusted to give effect to the exchange ratio) or a stock appreciation right subject to cash settlement and remained subject to the same terms and conditions of the Opnext equity plan and the applicable stock appreciation right agreement as in effect immediately prior to the acquisition.
In connection with the acquisition: (i) 91,467,739 shares of Opnext common stock were converted into the right to receive 38,416,355 shares of our common stock; (ii) outstanding options to purchase 10,119,340 shares of Opnext common stock were converted into options to purchase 4,250,011 shares of our common stock; and (iii) stock appreciation rights ("SARs") with respect to 412,123 shares of Opnext common stock were converted into SARs with respect to 172,970 shares of our common stock. Immediately following the effective time of the merger, Oclaro stockholders immediately prior to the merger owned approximately 57 percent and Opnext’s stockholders owned approximately 43 percent of the combined company. The combination is intended to qualify as a tax-free reorganization for federal income tax purposes. We accounted for this acquisition under the purchase method of accounting. The estimated fair value of assets acquired and liabilities assumed and the results of operations of Opnext from the closing date of the acquisition, July 23, 2012, are included in our consolidated financial statements at June 28, 2014 and June 29, 2013 and for the years then ended.
For accounting purposes, the fair value of the consideration paid to Opnext stockholders in the acquisition was $89.8 million; which includes the fair value of $88.7 million in common stock, based on the 38.4 million shares of common stock issued at a price of $2.31 per share, which was the closing market price of our common stock on the day the acquisition was consummated; and $1.1 million representing the fair value of vested stock options and SARs to purchase our common stock that we assumed.

Common shares issued to Opnext stockholders	$	88,742
Estimated fair value of vested stock options assumed	1,095
Estimated fair value of vested stock appreciation rights assumed	5
Total consideration	$	89,842
The total consideration given to former stockholders of Opnext has been allocated to the assets acquired and liabilities assumed based on their estimated relative fair values as of the date of the acquisition. Because of the complexities involved with performing our valuation, we initially recorded the tangible and intangible assets acquired and liabilities assumed based upon preliminary management estimates of their fair values as of July 23, 2012. During the fourth quarter of fiscal year 2013, we completed our fair value assessment of the Opnext acquisition, which resulted in changes to the estimated fair values of the assets acquired and liabilities assumed from the amounts we previously reported in our Quarterly Reports on Form 10-Q during fiscal year 2013.
Our final purchase price allocation, as adjusted, is as follows:
	Purchase
	Price
	Allocation
	(Thousands)
Cash and cash equivalents	$	36,123
Restricted cash	20,000
Accounts receivable	55,572
Inventories	68,011

Estimate of the fair value of assets acquired and liabilities assumed	114,708
Gain on bargain purchase	(24,866		)
Total purchase price	$	89,842
The fair value of raw materials inventories were based on historical cost on a first-in first-out basis, reduced to reflect amounts related to inventory we believe will prove to be unsalable. Products may be unsalable because they are technically obsolete due to substitute products, specification changes or excess inventory relative to customer forecasts. Work in process, finished goods and spare parts were valued using the comparative sales method, which estimates the expected sales price of the subject inventory, reduced for all costs expected to be incurred in its completion (for work in process), disposition and a profit on those efforts. Work in process, finished goods and spare parts were also reduced to reflect amounts related to inventory we believe will prove to be unsalable.
The preliminary fair value of property and equipment was determined using management estimates based on currently available information and a high-level review of similar historical transactions completed by us during the previous three fiscal years. In the third and fourth quarters of fiscal year 2013, we adjusted our initial estimates by reducing the fair value of property and equipment by a total of $4.0 million based on completing our valuation. We recorded a corresponding reduction in our gain on bargain purchase as of the acquisition date and adjusted depreciation expense for all interim periods to reflect the revised fair value estimate as of the acquisition date.
During the fourth quarter of fiscal year 2013, we reduced the preliminary fair value of the capital lease obligations by $1.0 million upon completion of our valuation.
The fair value of intangible assets was based on internal assessments using the “income approach,” which requires an estimate or forecast of all the expected future cash flows through the application of the multi-period excess earnings method, relief-from-royalty method or other acceptable methods. During the fourth quarter of fiscal year 2013, we completed our valuation and identified the following significant intangible assets: $8.7 million of developed technology with an estimated weighted average useful life of 6 years, $0.2 million of contract backlog with an estimated weighted average useful life of 1 year, $4.9 million of customer relationships with an estimated weighted average useful life of 11 years, and $2.7 million of trademarks and other with an estimated weighted average useful life of 6 years.
Any excess of the fair value of assets acquired and liabilities assumed over the aggregate consideration given for such acquisition results in a gain on bargain purchase. In the first quarter of fiscal year 2013, we initially recorded a gain on bargain purchase of $39.5 million in connection with the acquisition of Opnext, which was subsequently adjusted to $24.9 million in the fourth quarter of fiscal year 2013, upon completing our purchase price allocation and finalizing our fair value estimates of assets acquired and liabilities assumed.
The bargain purchase gain of $24.9 million results from the difference between the fair value of consideration given and our estimate of the fair value of assets acquired and liabilities assumed. The consideration given for Opnext consisted of a fixed number of our shares for each Opnext Share (0.42 for one), which was agreed upon on March 26, 2012. On that date, the closing price of our common stock was $4.66. At the consummation of the merger on July 23, 2012, the closing price of our common stock was $2.31. This share price, multiplied by the fixed number of our shares outstanding at the merger, and including the fair value of vested stock awards assumed by us, resulted in the fair value of consideration given being $89.8 million, less than the estimate of the fair market value of the net assets acquired and liabilities assumed of $114.7 million.
Upon the close of the acquisition, the combined company implemented significant workforce restructuring actions. Among other things, we combined our global sales, finance, legal and human resources operations. We also realigned our global operations and business units under a single management structure. Our newly combined global organizations provide services for both the pre-acquisition Oclaro and former Opnext products. We have also reduced redundant product offerings by eliminating selected products from each predecessor company and transitioned existing customers for such products to the other company’s current offering. In addition, we have merged our research and development efforts along product families, so many of our new product introductions going forward will benefit from both Oclaro and Opnext technology. For these reasons, we believe it would be impracticable to allocate revenues going forward to one predecessor entity or the other and to separately disclose revenues and earnings of Opnext since the acquisition date.
Asset Sale
In December 2011, we entered into an asset sale agreement to sell certain assets related to a legacy product, including inventory, equipment and intangibles, in exchange for $3.9 million of initial consideration plus potential earnout consideration based on the purchaser’s revenues from the legacy product over a 15 months period following the closing date. As of June 30, 2012, we received the full $3.9 million of the initial consideration.
During the year ended June 30, 2012, we completed the asset transfer and recognized a gain of $1.9 million within restructuring, acquisition and related (income) expense, net in the consolidated statements of operations. In fiscal year 2013, we recorded $0.4 million earnout consideration related to this agreement. Earnout consideration is recognized in the period it is reported to us as due, provided we believe cash collections are reasonably assured.
Acquisition of Mintera
On July 21, 2010, we acquired Mintera, a privately-held company providing high-performance optical transport sub-systems solutions. We accounted for the assets acquired and liabilities assumed from this acquisition using the purchase method of accounting. Under the terms of this agreement, we paid $10.5 million in cash to the former security holders and creditors of Mintera at the time of close and assumed $1.5 million in liabilities due by the security holders of Mintera, which we paid during fiscal year 2011.
We also agreed to pay additional revenue-based consideration whereby former security holders of Mintera were entitled to receive up to $20.0 million. The earnout consideration was payable in cash or, at our option, newly issued shares of our common stock, or a combination of cash and stock. During the year ended June 30, 2012, we recorded a $2.2 million decrease in the fair value of these earnout obligations within restructuring, acquisition and related (income) expense, net in the consolidated statements of operations. During fiscal year 2012, we settled the 12 month earnout obligation with the former security holders by paying them $0.5 million in cash and issuing 0.8 million shares of our common stock valued at $2.8 million. During fiscal year 2012, we also settled a portion of the 18 month earnout obligation with the former security holders by paying them $2.2 million in cash. The remaining 18 month earnout obligation of $8.6 million was settled in fiscal year 2013.
For accounting purposes, the total fair value of consideration given in connection with the acquisition of Mintera was $25.6 million, We recorded goodwill of $10.9 million in connection with the acquisition. In fiscal year 2013, we determined the goodwill related to this acquisition was impaired. Refer to Note 4, Goodwill and Other Intangible Assets for more information on the impairment of the goodwill.

	GOODWILL AND OTHER INTANGIBLE ASSETS
	Additions and Dispositions
	In connection with our sale of the Zurich Business, we transferred certain of our other intangible assets to II-VI. As of September 12, 2013, the date of the sale, and as of June 29, 2013, these other intangible assets had no carrying value. For the year ended June 29, 2013, we recorded $0.3 million in amortization related to these intangible assets, which has been reclassified to discontinued operations in the consolidated statements of operations.
	In connection with our acquisition of Opnext on July 23, 2012, we recorded $16.4 million in other intangible assets as our estimate of the fair value of acquired intangible assets. The intangible assets acquired from Opnext consist of $8.7 million of developed technology with an estimated weighted average useful life of 6 years, $0.2 million of contract backlog with an estimated weighted average useful life of 1 year, $4.9 million of customer relationships with an estimated weighted average useful life of 11 years, and $2.7 million of trademarks and other with an estimated weighted average useful life of 6 years.
	In connection with our acquisition of Mintera on July 21, 2010, we recorded $10.9 million in goodwill and $11.7 million in other intangible assets. The other intangible assets acquired from Mintera consist of core and current technology assets of $6.0 million with a weighted-average life of 6 years, a development agreement of $3.4 million with a weighted-average life of 7 years, customer relationships of $1.4 million with a weighted-average life of 8.5 years, manufacturing software of $0.7 million with a weighted-average life of 6 years, patents of $0.1 million with a weighted-average life of 5.5 years, trade names of $0.1 million with a weighted-average life of 1.5 years and backlog of $30,000 with a weighted-average life of 1.5 years.
	Impairment Assessments
	During the fourth quarter of fiscal year 2014, we reviewed our other intangible assets for impairment. We compared their carrying amounts to market prices or the future undiscounted cash flows the assets are expected to generate. We determined that the carrying value of the assets did not exceed the fair value based on market prices or future discounted cash flows. We did not record any impairment charges in fiscal year 2014.
	During the fourth quarter of fiscal year 2013, we performed an annual analysis for potential impairment of our goodwill, which included examining the impact of current general economic conditions on our future prospects, the decline in our market capitalization, and the anticipated resizing of our operations with the recent sale of certain of our products and/or businesses. The first step of testing goodwill for impairment is based on a reporting unit’s “fair value,” which is generally determined through market prices. In certain cases, due to the absence of market prices for a particular element of our business, we have elected to base our analysis on discounted future expected cash flows. Based on this analysis, we concluded that our remaining goodwill on our consolidated balance sheet, which relates to our acquisition of Mintera, was impaired. We performed a second step impairment analysis, which indicated that the goodwill in connection with the Mintera reporting unit was fully impaired. Based upon this evaluation, we recorded $10.9 million for the goodwill impairment loss in our consolidated statement of operations for the year ended June 29, 2013. The impairment did not result in any cash expenditures. In connection with our second step goodwill impairment analysis, we also evaluated the fair value of our other intangible assets in this reporting unit, and our other reporting units, and concluded that based on declines in our forecasts, our decision to sell or abandon certain product lines and other factors, certain of these other intangible assets were also impaired as of June 29, 2013. We recorded impairment losses of $6.4 million related to intangibles acquired in connection with our acquisition of Mintera, $2.6 million related to intangibles acquired in connection with our acquisition of Opnext, and $5.2 million related to intangibles acquired in connection with other earlier acquisitions.
	In addition, during fiscal year 2013, we determined that a portion of the technology we acquired in connection with our acquisition of Mintera in July 2010 was considered redundant, following the acquisition of Opnext and its product lines. We recorded $0.9 million for the impairment loss related to these intangibles in goodwill and other intangible assets in our consolidated statement of operations for the year ended June 29, 2013.
	Amortization
	Amortization of other intangible assets for the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, was $1.7 million, $5.0 million and $2.7 million, respectively. Amortization is recorded as an operating expense within the consolidated statements of operations.

Restructuring and Related Activities [Abstract]	'
Restructuring Liabilities	'
	RESTRUCTURING LIABILITIES
	2014 Restructuring Plan
	During the first quarter of fiscal year 2014, we initiated a restructuring plan to simplify our operating footprint, reduce our cost structure and focus our research and development investment in the optical communications market where we can leverage our core competencies. During the year ended June 28, 2014, we recorded restructuring charges of $13.2 million pursuant to this plan, consisting of $8.5 million related to workforce reductions, $2.9 million related to transferring production capabilities of our 10G InP products in-house from one of our contract manufacturers, $0.8 million related to a facility lease loss liability, $0.7 million related to the write-off of certain fixed assets in connection with our relocation of our manufacturing and research and development facilities from Totsuka, Japan, and $0.3 million in other lease cancellations and commitments. During the year ended June 28, 2014, we paid $8.5 million to settle a portion of these restructuring liabilities. As of June 28, 2014, we had $2.2 million in accrued restructuring liabilities related to this restructuring plan. We expect to incur an additional $2.5 million to $6.5 million in restructuring charges over the course of the next year in connection with the ongoing activities related to this restructuring plan.
	Opnext Restructuring
	In connection with the acquisition of Opnext, we initiated a restructuring plan to integrate the businesses in the first quarter of fiscal year 2013. In connection with the integration, we recorded $1.1 million and $12.1 million in restructuring charges during the year ended June 28, 2014 and June 29, 2013, respectively. The restructuring charges in fiscal year 2014 included $0.9 million related to external consulting charges and professional fees associated with reorganizing the infrastructure and $0.1 million related to revised estimates for lease cancellations and commitments. The restructuring charges in fiscal year 2013 included $10.5 million related to workforce reductions, $0.9 million related to the impairment of certain technology that is now considered redundant following the acquisition, $0.4 million related to the write-off of net book value inventory that supported this technology, and $0.3 million related to revised estimates for lease cancellations and commitments. Included in our restructuring charges during fiscal year 2013, we recorded $2.2 million relating to the separation agreement with our former Chief Executive Officer.
	During the year ended June 28, 2014 and June 29, 2013, we made scheduled payments of $2.2 million and $8.0 million, respectively, to settle these restructuring liabilities. During the year ended June 28, 2014 and June 29, 2013, we also paid $1.8 million and $0.3 million, respectively, to settle the liability related to the separation agreement with our former Chief Executive Officer. As of June 28, 2014, we had no remaining accrued restructuring liabilities related to this restructuring plan.
	Restructuring Plan related to our Manufacturing Operations in Shenzhen, China
	During fiscal year 2012, we initiated a restructuring plan in connection with the transfer of a portion of our Shenzhen, China manufacturing operations to Venture Corporation Limited ("Venture"). This transition is scheduled to occur in a phased and gradual transfer of products over three years, which is scheduled to be completed in fiscal year 2015. In connection with this transition, we recorded restructuring charges of $3.5 million, $5.1 million and $6.0 million during the year ended June 28, 2014, June 29, 2013 and June 30, 2012, respectively. All of the restructuring charges in fiscal year 2014, 2013 and 2012 related to employee separation charges.
	During fiscal year 2014, 2013 and 2012, we made scheduled payments of $7.1 million, $2.7 million and $3.9 million, respectively, to settle these restructuring liabilities. As of June 28, 2014, we had $0.6 million in accrued restructuring liabilities related to this restructuring plan. As of June 28, 2014, we expect to incur an additional $1.5 million to $2.5 million in restructuring costs as we complete the transfer of certain of our manufacturing operations to Venture in fiscal year 2015.
	Earlier Restructuring Plans
	During fiscal year 2012, we incurred $1.4 million in restructuring charges related to earlier plans of restructuring. During fiscal year 2012 we made scheduled payments and/or recorded reductions to our restructuring reserves of $1.2 million, reducing the related lease liabilities and employee severance and retention obligations. We do not expect to incur additional restructuring costs in connection with these previously announced restructuring plans.
	For all periods presented, separation payments under the restructuring and cost reduction efforts were accrued and charged to restructuring in the period that the amounts were both determined and communicated to the affected employees.
	The following table summarizes the activity related to our restructuring liability for the years ended June 28, 2014, June 29, 2013 and June 30, 2012:

	FLOOD-RELATED (INCOME) EXPENSE, NET
	In October 2011, certain areas in Thailand suffered major flooding as a result of monsoons. This flooding had a material impact on our business and results of operations in fiscal years 2012 and 2013. Our primary contract manufacturer, Fabrinet, suspended operations at two factories located in Chokchai, Thailand and Pinehurst, Thailand. The Chokchai factory suffered extensive flood damage and became inaccessible due to high water levels inside and surrounding the manufacturing facility. As a result of this flooding, we experienced a significant decline in product sales due to our inability or limited ability to manufacture certain of our products and we incurred significant damage to our inventory and property and equipment located at the Chokchai facility.
	During the year ended June 28, 2014, we recorded $1.8 million in net flood-related income in our consolidated statement of operations, primarily consisting of $3.7 million in insurance settlement proceeds received in the second and third quarters of fiscal year 2014 and adjustments to retainers for professional services of $0.1 million, partially offset by an out-of-period adjustment of $2.0 million related to the impairment of leased assets assumed pursuant to the Opnext merger that had been damaged by the flooding. Approximately $1.5 million of the $3.7 million received in fiscal year 2014 represents payments against insurance claims filed under the former Opnext entity.
	During the year ended June 29, 2013, we recorded net flood-related income of $29.5 million comprised of $30.8 million in settlement payments, offset in part by $1.3 million in professional fees and related expenses incurred in connection with our recovery efforts. Approximately $14.0 million of the $30.8 million received in fiscal year 2013 represents payments against insurance claims filed under the former Opnext entity.
	During the year ended June 30, 2012, we recorded net flood-related expense of $2.5 million, including impairment charges of $8.2 million related to the write-off of the net book value of damaged inventory and property and equipment based on estimates of the damage caused by the flooding and $5.3 million of personnel-related costs, professional fees and related expenses incurred in connection with our recovery efforts, partially offset by $11.0 million in settlement payments relating to losses we incurred due to the flooding in Thailand.
	The flood-related benefits and charges are recorded within the operating expense caption flood-related (income) expense, net in our consolidated statements of operations.
	Flood-related (income) expense, net for the year ended June 28, 2014, June 29, 2013 and June 30, 2012 included the following:

	While we maintain both property and business interruption insurance coverage, there can be no assurance as to the amount or timing of future insurance recoveries. Insurance recoveries related to impairment losses previously recorded and other recoverable expenses will be recognized to the extent of the related loss or expense in the period that recoveries become probable and realizable. Insurance recoveries under business interruption coverage and insurance recovery gains in excess of amounts previously written-off related to impaired inventory and equipment or in excess of other recoverable expenses previously recognized will be recognized when they become realizable and all contingencies have been resolved. The evaluation of insurance recoveries requires estimates and judgments about future results which affect reported amounts and certain disclosures. Actual results could differ from those estimates.

	CREDIT LINE AND NOTES
	Silicon Valley Bank Credit Facility
	On March 28, 2014, Oclaro, Inc. and its subsidiary, Oclaro Technology Limited (the “Borrower”), entered into a loan and security agreement (the “Loan Agreement”) with Silicon Valley Bank (the “Bank”) pursuant to which the Bank provided the Borrower with a three-year revolving credit facility of up to $40.0 million. Under the Loan Agreement, advances are available based on up to 80 percent of “eligible accounts” as defined in the Loan Agreement. The Loan Agreement has a $10.0 million sub-facility for letters of credit, foreign exchange contracts and cash management services.
	The obligations of the Borrower under the Loan Agreement are guaranteed by us and certain subsidiaries of ours (collectively, the “Guarantors”) pursuant to an Unconditional Guaranty in favor of the Bank (the “Guaranty”), and are secured by substantially all of the assets of the Borrower and the Guarantors, including a pledge of the capital stock holdings of the Borrower and the Guarantors in their direct subsidiaries.
	Borrowings made under the Loan Agreement bear interest at a rate based on either the London Interbank Offered Rate plus 2.25 percent or Wall Street Journal’s prime rate plus 1.00 percent. If the sum of (a) the Borrower’s unrestricted cash and cash equivalents that are subject to the Bank’s liens less (b) the amount outstanding to the Bank under the Loan Agreement (such sum being “Net Cash”) is less than $15.0 million, then the interest rates are increased by 0.75 percent until Net Cash exceeds $15.0 million for a calendar month. If interest paid under the Loan Agreement is less than $45,000 in any fiscal quarter, the Borrower is required to pay the Bank an additional amount equal to the difference between $45,000 and the actual interest paid during such fiscal quarter. The minimum interest payment is in lieu of a stand-by charge.
	The obligations of the Borrower under the Loan Agreement may be accelerated, and the Guarantors may become obligated under the Guaranty, upon the occurrence of an event of default under the Loan Agreement. The Loan Agreement includes customary events of default. Upon the occurrence and during the continuance of an event of default, obligations shall bear interest at a rate per annum which is 2 percentage points above the rate that is otherwise applicable thereto, unless the Bank elects otherwise, in its sole discretion.
	The Loan Agreement contains covenants applicable to us, the Borrower and our subsidiaries, including a financial covenant that, on a consolidated basis, requires us to maintain a minimum fixed charge coverage ratio of no less than 1.10 to 1.00, if the Borrower has not maintained Net Cash of at least $15.0 million, and other customary covenants. The Loan Agreement also contains restrictions on our ability to pay cash dividends on our common stock.
	If the Loan Agreement terminates prior to its maturity date, the Borrower will pay a termination fee equal to 1.00 percent of the total credit facility if such termination occurs in the first year after closing, 0.75 percent of the total credit facility if such termination occurs in the second year after closing and 0.50 percent of the total credit facility if such termination occurs in the third year after closing. The maturity date of the Loan Agreement is March 28, 2017.
	At June 28, 2014, there were no amounts outstanding under the Loan Agreement.
	Wells Fargo Credit Line and Term Loan
	On August 2, 2006, Oclaro, Inc., as the (“Parent”), along with Oclaro Technology Limited, (“Borrower”), Oclaro Photonics, Inc. and Oclaro Technology, Inc., each a wholly-owned subsidiary, entered into a Credit Agreement with Wells Fargo Capital Finance, Inc. ("Wells Fargo") and certain other lenders.
	In connection with the Credit Agreement, we paid an arrangement fee of $0.2 million, a closing fee of $0.3 million and agreed to pay a monthly servicing fee of $4,000 and an unused line fee equal to 0.375 percentage points per annum, payable monthly on the unused amount of revolving credit commitments. Borrowings made under the Credit Agreement bear interest at a rate based on either the London Interbank Offered Rate plus 2.50 percentage points or the bank’s prime rate plus 1.25 percentage points. During fiscal year 2014 and 2013, we made interest payments of $0.3 million and $1.2 million, respectively, in connection with the Credit Agreement.
	From time to time, we amended and restated the Credit Agreement, before terminating the agreement on March 14, 2014.
	•	On November 2, 2012, Borrower and the Parent entered into a Second Amended and Restated Credit Agreement with Wells Fargo and the other lenders regarding the senior secured revolving credit facility, increasing the facility size from $45.0 million to $50.0 million and extending the term thereof to November 2, 2017.
	•	On January 23, 2013, Silicon Valley Bank ("SVB") and Wells Fargo ("Agent"), collectively the Lenders, entered into a Joinder Agreement (the "Joinder Agreement") pursuant to the Second Amended and Restated Credit Agreement among Parent, Borrower, the Lenders and the Agent, as administrative agent for the Lenders. Pursuant to the Joinder Agreement, SVB agreed to become an additional Lender under the Second Amended and Restated Credit Agreement, and the Lenders agreed to increase the revolving credit facility under the Credit Agreement from $50.0 million to $80.0 million. In connection with the Joinder Agreement, the Parent paid SVB a lender fee of $0.2 million.
	•	On January 23, 2013, Parent, Borrower, the Lenders and the Agent entered into Amendment Number One to the Credit Agreement and the associated security agreements (the "Amendment"), pursuant to which the parties agreed that (i) the senior secured second lien notes due 2018 issued by Oclaro Luxembourg S.A. in the original principal amount of $25.0 million shall be applied against the maximum dollar limit of senior unsecured convertible notes that Parent may issue without the consent of Agent, and (ii) the cash balances of Opnext, Pine Photonics Communications, Inc., and Opnext Subsystems Inc. would be subject to a required sweep to the Agent’s account upon the occurrence of certain triggering events. Under the Credit Agreement advances are available based on up to 85 percent of “eligible accounts receivable,” as defined in the Credit Agreement.
	•	On May 6, 2013, Parent, Borrower, the Lenders, the Agent and PECM Strategic Funding LP and Providence TMT Debt Opportunity Fund II LP (the “Term Lenders”) entered into Amendment Number Two to the Credit Agreement and the associated guaranties and security agreements (“Amendment Number Two”), which amended the Credit Agreement in pertinent part by: (i) adding a $25 million, one year term loan (the “Term Loan”) to be provided by the Term Lenders; (ii) reducing the revolving credit facility from $80.0 million to $50.0 million (to be further reduced on a dollar-for-dollar basis by an amount equal to the net proceeds of certain asset sale transactions that the Parent may undertake in the future), eliminating the Borrower’s option to increase the revolving credit facility to $100.0 million and implementing an availability block under the revolving credit facility of at least $10.0 million; (iii) removing the financial covenants so that Borrower is not required to maintain a minimum of $15.0 million of availability under the revolving credit facility or $15.0 million in qualified cash balances; (iv) adding an affirmative covenant that Borrower shall have consummated one or more asset sales by July 15, 2013 and with a minimum threshold of net proceeds as set forth in the Amendment, and (v) providing for payments and proceeds of asset sales to be applied to repay the credit facility and the Term Loan (with the first $20.0 million of such proceeds being applied to repay Wells Fargo and SVB, the next $25.0 million being applied to repay the Term Lenders and the remaining proceeds being used to repay Wells Fargo and SVB all amounts outstanding under the credit facility), and events of default relating thereto. During a continuing event of default, the Agent or Lenders can declare any amounts outstanding under the Credit Agreement immediately due and payable.
	Interest on the Term Loan obligations accrued at a per annum rate equal to the sum of: (i) the PIK Term Loan Interest Rate, with such accrued interest to be capitalized quarterly and added to the outstanding principal balance of the Term Loan, and (b) the Cash Term Loan Interest Rate. The PIK Term Loan Interest Rate is 2.0 percent beginning on the effective date of the Term Loan (the “Effective Date”) up to but excluding the date six months thereafter, then it is 4.0 percent until the date twelve months after the Effective Date and then it is 5.0 percent. The Cash Term Loan Interest Rate is 7.0 percent beginning on the Effective Date up to but excluding the date six months thereafter, then it is 8.5 percent until the date twelve months after the Effective Date and then it is 10.0 percent.
	In connection with Amendment Number Two, the Borrower paid the revolving lenders an amendment fee of $0.5 million and the Term Lenders a closing fee of $2.1 million. These costs were capitalized and scheduled to be amortized straight-line to expense over the one year term of the loan. In connection with the Term Loan, we also issued certain warrants. The Term Lenders exercised these warrants in May 2014, which is more fully discussed in Note 10, Stockholders’ Equity.
	•	On August 21, 2013, Parent, Borrower, the Lenders and the Agent entered into Waiver and Amendment Number Three to the Credit Agreement, which amended the Credit Agreement in pertinent part by: (i) extending the date by which the Borrower shall have consummated one or more asset sales with a minimum threshold of net proceeds to September 2, 2013; (ii) eliminating the mandatory reduction of the revolving credit facility upon the consummation of the asset sales described in (i) above; and (iii) adding a covenant that the Borrower is required to maintain a minimum liquidity of at least $45.0 million at all times (liquidity being the sum of the Borrower’s excess availability under the revolving credit facility plus the lesser of $25.0 million and qualified cash balances). The Borrower paid the lenders an amendment fee of $0.7 million.
	Under the Credit Agreement, as amended, we were required to complete certain asset sales on or by September 2, 2013. We completed the sale of the Zurich Business on September 12, 2013 and applied the net proceeds to repay all amounts outstanding under the Credit Agreement. The event of default resulting from not completing the transaction on September 2, 2013 was waived on September 26, 2013. This waiver eliminated the requirement for the Agent and Lenders to make any advances, issue any letters of credit or provide any other extension of credit until the Agent and Lenders agree otherwise and prevented us from exercising any right or action set forth in the applicable loan documents that is conditioned on the absence of any event of default.
	•On March 14, 2014, we terminated the Credit Agreement.
	At June 28, 2014, there were no amounts outstanding under the Credit Agreement or the Term Loan. All amounts owed under the Credit Agreement and Term Loan were repaid during the first quarter of fiscal year 2014. During the year ended June 28, 2014, we recorded the remaining unamortized debt discount and issuance costs of $4.8 million related to the Term Loan in discontinued operations within the consolidated statement of operations for the year ended June 28, 2014. At June 29, 2013, there was $40.0 million outstanding under the Credit Agreement at an average interest rate of 2.9 percent per annum and $24.6 million outstanding related to the Term Loan at an average interest rate of 9 percent per annum.
	7.50% Exchangeable Senior Secured Second Lien Notes (convertible notes)
	On December 14, 2012, we and our indirect, wholly owned subsidiary, Oclaro Luxembourg S.A., closed the private placement of $25.0 million aggregate principal amount 7.50% Exchangeable Senior Secured Second Lien Notes due 2018 ("convertible notes"). The sale of the convertible notes resulted in net proceeds of approximately $22.8 million. The private placement was completed pursuant to a purchase agreement, dated December 14, 2012 entered into by us, certain of our domestic and foreign subsidiaries (the "Guarantors") and Morgan Stanley & Co. LLC. The convertible notes are governed by an Indenture, entered into by us and the Guarantors with Wells Fargo Bank, National Association, as trustee and second lien collateral agent (the "Trustee"). The Indenture contains affirmative and negative covenants that, among other things, limit the ability of us and the Guarantors to incur, assume or guarantee additional indebtedness; make restricted payments including, without limitation, paying dividends, repurchasing capital stock and redeeming debt that is junior in right of payment to the convertible notes; create liens; sell or otherwise dispose of assets, including capital stock of subsidiaries; and enter into mergers and consolidations. The Indenture also contains customary events of default. Upon the occurrence of certain events of default, the Trustee or the holders of the convertible notes may declare all outstanding convertible notes to be due and payable immediately. The convertible notes are unconditionally guaranteed, jointly and severally, on a senior secured basis by us and all of the Guarantors.
	Under the terms of the convertible notes, on or after December 15, 2013, in the event that the last reported sale price of our common stock for 20 or more trading days (whether or not consecutive) in a period of 30 consecutive trading days ending within five trading days immediately prior to the date that we receive a notice of exchange exceeded the exchange price in effect on each such trading day, we were obliged, in addition to delivering shares upon exchange by the holder of convertible notes, together with cash in lieu of fractional shares, to make a “make-whole premium” payment in cash equal to the sum of the present value of the remaining scheduled payments of interest on the convertible notes to be exchanged through the maturity date computed using a discount rate equal to 0.50 percent. The initial exchange price was $1.846 per share of common stock. Any holder that exchanged its convertible notes after such holder’s convertible notes had been called for redemption by us would, in addition to receiving shares of common stock deliverable upon such exchange and cash in lieu of fractional shares, receive a payment (the “redemption exchange make-whole payment”) in cash equal to the sum of the remaining scheduled payments of interest that would have been made on the convertible notes to be exchanged had such convertible notes remained outstanding from the applicable exchange date to the maturity date. If the redemption exchange make-whole payment is payable upon exchange of a holder’s convertible notes, then such holder would not receive the “make-whole premium” payment described above.
	We considered the contingent obligation of having to make a make-whole payment in the event of an early conversion by the holders of the convertible notes as an embedded derivative. On December 19, 2013, the holders exercised their rights to exchange the convertible notes for our common stock. The exchange rate for the exchanges was 541.7118 shares of common stock per $1,000 in principal amount of convertible notes. We issued 13,542,791 shares of common stock in connection with the exchange, with cash payable in lieu of fractional shares. In addition, pursuant to the terms of the indenture governing the convertible notes, we made a redemption exchange make-whole payment of $8.3 million, which we recorded in interest (income) expense, net, in the consolidated statements of operations for the year ended June 28, 2014.
	During the year ended June 28, 2014 and June 29, 2013, we recorded and paid $0.9 million and $0.9 million, respectively, in routine interest payments related to these convertible notes. Interest on the convertible notes was payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2013.
	In connection with the private placement of the convertible notes, we incurred approximately $1.3 million in debt discount and $0.9 million in issuance costs. Upon exchange of the convertible notes during the second quarter of fiscal year 2014, we recorded the remaining unamortized debt discount and issuance costs of $1.8 million in additional paid-in capital within the consolidated balance sheet.
	The following table sets forth balance sheet information related to the convertible notes at June 28, 2014 and June 29, 2013:

	Sumitomo Note
	In connection with the acquisition of Opnext, we assumed a 1.5 billion Japanese yen note payable (approximately $19.2 million at July 23, 2012) to The Sumitomo Trust Bank ("Sumitomo"). The note was due monthly unless renewed by Sumitomo. During the fourth quarter of fiscal year 2013, we repaid the entire $14.7 million note payable. As of June 29, 2013, we had no outstanding loan balance with Sumitomo. Interest expense for the year ended June 29, 2013 was $0.3 million. Interest accrued and was paid monthly at the Tokyo Interbank Offered Rate plus a premium, which for our fiscal year 2013 was 1.7 percent per annum.

	401(k) Plan
	In the U.S., we sponsor a 401(k) plan that allows voluntary contributions by eligible employees, who may elect to contribute up to the maximum allowed under the U.S. Internal Revenue Service regulations. We generally make 100 percent matching contributions on the first 3 percent and 50 percent matching contributions on the following 2 percent (up to a maximum of $10,400 per eligible employee for calendar year 2014) and we recorded related expenses of $0.8 million, $1.4 million and $1.0 million in fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, respectively, including amounts related to our discontinued operations.
	Defined Contribution Plan
	We contribute to a U.K. based defined contribution pension scheme for employees. Contributions under this plan and the related expenses were $1.4 million, $1.3 million and $1.4 million in the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, respectively.
	Switzerland Defined Benefit Plan
	During the first quarter of fiscal year 2014, we sold our Zurich Business, and as part of the sale transferred our pension plan covering employees of our Swiss subsidiary (the “Swiss Plan”) to II-VI. At the end of our first quarter of fiscal year 2014, we had no remaining obligations under the Swiss Plan.
	Net periodic pension costs associated with our Swiss Plan are recorded in discontinued operations and included the following components in fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012:

	Prior to transferring our pension plan to II-VI in the first quarter of fiscal year 2014, we contributed $0.5 million to our Swiss Plan. During the fiscal years ended June 29, 2013 and June 30, 2012, we contributed $2.3 million and $2.4 million, respectively, to our Swiss Plan.
	Japan Defined Contribution and Benefit Plan
	In connection with our acquisition of Opnext, we assumed a defined contribution plan and a defined benefit plan that provides retirement benefits to our employees in Japan.
	Under the defined contribution plan, contributions are provided based on grade level and totaled $0.8 million and $0.9 million for the year ended June 28, 2014 and June 29, 2013, respectively. Employees can elect to receive the benefit as additional salary or contribute the benefit to the plan on a tax-deferred basis. Under the defined benefit plan in Japan (the "Japan Plan"), we calculate benefits based on an employee’s individual grade level and years of service. Employees are entitled to a lump sum benefit upon retirement or upon certain instances of termination. As of June 28, 2014, there were no plan assets.
	The reconciliation of the actuarial present value of the projected benefit obligations for the defined benefit plan for the year ended June 28, 2014 and June 29, 2013 was as follows:

	COMMITMENTS AND CONTINGENCIES
	Loss Contingencies
	We are involved in various lawsuits, claims, and proceedings that arise in the ordinary course of business. We record a loss provision when we believe it is both probable that a liability has been incurred and the amount can be reasonably estimated.
	Guarantees
	We indemnify our directors and certain employees as permitted by law, and have entered into indemnification agreements with our directors and executive officers. We have not recorded a liability associated with these indemnification arrangements, as we historically have not incurred any material costs associated with such indemnification obligations. Costs associated with such indemnification obligations may be mitigated by insurance coverage that we maintain, however, such insurance may not cover any, or may cover only a portion of, the amounts we may be required to pay. In addition, we may not be able to maintain such insurance coverage in the future.
	We also have indemnification clauses in various contracts that we enter into in the normal course of business, such as indemnifications in favor of customers in respect of liabilities they may incur as a result of purchasing our products should such products infringe the intellectual property rights of a third party. We have not historically paid out any material amounts related to these indemnifications; therefore, no accrual has been made for these indemnifications.
	Warranty Accrual
	We generally provide a warranty for our products for twelve to thirty-six months from the date of sale, although warranties for certain of our products may be longer. We accrue for the estimated costs to provide warranty services at the time revenue is recognized. Our estimate of costs to service our warranty obligations is based on historical experience and expectation of future conditions. To the extent we experience increased warranty claim activity or increased costs associated with servicing those claims, our warranty costs would increase, resulting in a decrease in gross profit.
	The following table summarizes movements in the warranty accrual for the periods indicated:

	Capital Leases
	In connection with our acquisition of Opnext, we assumed certain capital leases with Hitachi Capital Corporation, a related party, for certain equipment. The terms of the leases generally range from one to five years and the equipment can be purchased at the residual value upon expiration. We can terminate the leases at our discretion in return for a penalty payment as stated in the lease contracts.

	Operating Leases
	We lease certain facilities under non-cancelable operating lease agreements that expire at various dates through 2033. Our future fiscal year minimum lease payments under non-cancelable operating leases and related sublease income, including the sale-leaseback of our Caswell and Shenzhen facilities, are as follows:
		Operating			Sublease
		Lease Payments			Income
		(Thousands)

	2019	7,408			—
	Thereafter	64,202			—
		$	106,733		$	(453	)
	Rent expense for these leases was $8.6 million, $12.6 million and $7.3 million during the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, respectively, including our discontinued operations.
	We continue to lease one building in Acton, Massachusetts, which we previously used to house the manufacturing and research and development related to certain of our products which was considered redundant, following the acquisition of Opnext and its product lines. The lease for the building is scheduled to expire on January 31, 2016, with a current rental cost of approximately $0.5 million annually. In determining our facility lease loss liability, various assumptions were made, including the time period over which the buildings will be vacant, expected sublease terms and expected sublease rates. During the fourth quarter of fiscal year 2014, we recorded a lease loss liability of $0.8 million related to this facility. Adjustments to this accrual will be made in future periods, if events and circumstances change.
	Taxes
	It is our policy to classify accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. For fiscal years 2014, 2013 and 2012, we recognized an insignificant amount of interest and penalties related to unrecognized tax benefits. As of June 28, 2014 and June 29, 2013, we accrued $0.9 million and $0.7 million, respectively, of interest and penalties related to unrecognized tax benefits. At this time, we are unable to reasonably estimate the timing of the long-term payments or the amount by which the liability will increase or decrease over time.
	Purchase Commitments
	We purchase components from a variety of suppliers and use contract manufacturers to provide manufacturing services for our products. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, we enter into agreements with suppliers and contract manufacturers that either allow them to procure inventory based upon criteria as defined by us or establish the parameters defining our requirements. A significant portion of our reported purchase commitments arising from these agreements consist of firm, non-cancelable and unconditional commitments. As of June 28, 2014, we had total purchase commitments of $81.7 million.
	We record a liability for firm, non-cancelable and unconditional purchase commitments for quantities in excess of its future demand forecasts consistent with the valuation of our excess and obsolete inventory. As of June 28, 2014, the liability for these purchase commitments was $0.7 million and was included in other non-current liabilities.
	Litigation
	Overview
	In the ordinary course of business, we are involved in various legal proceedings, and we anticipate that additional actions will be brought against us in the future. The most significant of these proceedings are described below. These legal proceedings, as well as other matters, involve various aspects of our business and a variety of claims in various jurisdictions. Complex legal proceedings frequently extend for several years, and a number of the matters pending against us are at very early stages of the legal process. As a result, some pending matters have not yet progressed sufficiently through discovery and/or development of important factual information and legal issues to enable us to determine whether the proceeding is material to us or to estimate a range of possible loss, if any. Unless otherwise disclosed, we are unable to estimate the possible loss or range of loss for the legal proceedings described below. While it is not possible to accurately predict or determine the eventual outcomes of these items, an adverse determination in one or more of these items currently pending could have a material adverse effect on our results of operations, financial position or cash flows.
	Raysung Commercial Litigation
	On October 23, 2013, Xi’an Raysung Photonics Inc., or Raysung, filed a civil suit against our wholly-owned subsidiary, Oclaro Technology (Shenzhen) Co., Ltd. (formerly known as Bookham Technology (Shenzhen) Co., Ltd.), or Oclaro Shenzhen, in the Xi’an Intermediate People’s Court in Shaanxi Province of the People’s Republic of China, or the Xi’an Court. The complaint filed by Raysung alleges that Oclaro Shenzhen terminated its purchase order pursuant to which Raysung had supplied certain products and was to supply certain products to Oclaro Shenzhen.
	Raysung has requested the court award damages of approximately $0.8 million (equivalent to RMB 4,796,531), and requested that Oclaro Shenzhen take the finished products that are now stored in Raysung’s warehouse (the value of the finished product is approximately $2.2 million, (equivalent to RMB 13,505,162) and requested that Oclaro Shenzhen pay its court fees in connection with this suit.
	The Xi’an Court delivered an Asset Preservation Order which was served on Oclaro Shenzhen and the local Customs office. According to the Asset Preservation Order, Oclaro Shenzhen was ordered to maintain approximately $2.4 million (equivalent to RMB 15,000,000) or assets equivalent to the said amount during the litigation process, and the Customs office was ordered to restrict Oclaro Shenzhen's equipment from being exported before the Asset Preservation Order is lifted. On November 11, 2013, Oclaro Shenzhen entered into a settlement agreement. Under the terms of this settlement agreement, Oclaro Shenzhen agreed to pay $500,000 in payment of invoices for certain materials to Raysung and to work with Raysung to requalify it as a vendor for certain Oclaro Shenzhen manufacturing requirements, in consideration of which Raysung agreed to submit the settlement agreement to the Xi’an Court so it could issue a civil mediation agreement, apply for a discharge of the Asset Preservation Order and waive the right to bring any legal actions against Oclaro Shenzhen relating to these matters. Oclaro Shenzhen performed its obligations under the settlement agreement, however, on January 15, 2014, Raysung applied to the Xi’an Court to terminate the settlement agreement and add Oclaro, Inc. as a co-defendant in the original civil suit.
	On March 26, 2014, the Xi’an Court froze approximately $2.4 million (equivalent to RMB 15 million) of cash held in Oclaro Shenzhen’s bank account in China. On April 30, 2014, Oclaro Shenzhen submitted a challenge to the jurisdiction of the Xi'an Court. On May 26, 2014, the Xi'an Court overruled the jurisdictional challenge. On June 4, 2014, Oclaro Shenzhen filed an appeal with the Shaanxi High Court to revoke the civil order of the Xi'an Court overruling Oclaro Shenzhen's jurisdictional challenge. The Shaanxi High Court held hearings on July 15, 2014 and July 30, 2014, and on August 20, 2014 sustained the Xi'an Court's civil order on jurisdiction and transferred the case back to the Xi'an Court for substantive proceedings. Oclaro, Inc. and Oclaro Shenzhen believe that they have meritorious defenses to the claims made by Raysung and intend to defend this litigation vigorously.
Class Action and Derivative Litigation
On May 19, 2011, Curtis and Charlotte Westley filed a purported class action complaint in the United States District Court for the Northern District of California, against us and certain of our officers and directors. The Court subsequently appointed the Connecticut Laborers’ Pension Fund (“Pension Fund”) as lead plaintiff for the putative class. On April 26, 2012, the Pension Fund filed a second amended complaint, captioned as Westley v. Oclaro, Inc., No. 11 Civ. 2448 EMC, allegedly on behalf of persons who purchased our common stock between May 6 and October 28, 2010, alleging that we and certain of our officers and directors issued materially false and misleading statements during this time period regarding our current business and financial condition, including projections for demand for our products, as well as our revenues, earnings, and gross margins, for the first quarter of fiscal year 2011 as well as the full fiscal year. The complaint alleged violations of section 10(b) of the Securities Exchange Act and Securities and Exchange Commission Rule 10b-5, as well as section 20(a) of the Securities Exchange Act. The complaint sought damages and costs of an unspecified amount. On September 21, 2012, the Court dismissed the second amended complaint with leave to amend. After the Pension Fund moved for reconsideration, on January 10, 2013, the Court allowed plaintiffs to take discovery regarding statements made in May and June 2010. On March 1, 2013 the Pension Fund filed a third amended complaint, attempting to cure pleading deficiencies with regard to statements allegedly made in July and August 2010. On April 1, 2013, defendants moved to dismiss the third amended complaint with respect to the statements made in July and August 2010. On May 30, 2013, the Court granted Defendants’ motion to dismiss the complaint’s claims based on statements made in July and August 2010. Although discovery has commenced, no trial was ever scheduled in this action.
On June 10, 2011, a purported shareholder, Stanley Moskal, filed a purported derivative action in the Superior Court for the State of California, County of Santa Clara, against us, as nominal defendant, and certain of our current and former officers and directors, as defendants. The case is styled Moskal v. Couder, No. 1:11 CV 202880 (Santa Clara County Super. Ct., filed June 10, 2011). Four other purported shareholders, Matteo Guindani, Jermaine Coney, Jefferson Braman and Toby Aguilar, separately filed substantially similar lawsuits in the United States District Court for the Northern District of California on June 27, June 28, July 7 and July 26, 2011, respectively. By Order dated September 14, 2011, the Guindani, Coney, and Braman actions were consolidated under In re Oclaro, Inc. Derivative Litigation, Lead Case No. 11 Civ. 3176 EMC. On October 5, 2011, the Aguilar action was voluntarily dismissed. Each remaining purported derivative complaint alleged that Oclaro has been, or will be, damaged by the actions alleged in the Westley complaint, and the litigation of the Westley action, and any damages or settlement paid in the Westley action. Each purported derivative complaint alleged counts for breaches of fiduciary duty, waste, and unjust enrichment. Each purported derivative complaint sought damages and costs of an unspecified amount, as well as injunctive relief. By Order dated March 6, 2012, the parties in the Moskal action agreed that defendants shall not be required to respond to the original complaint. By Order dated February 27, 2013, the parties in the Moskal action agreed that plaintiff would serve an amended complaint no later than 30 days after the Court in the Westley action rules on defendants’ motion to dismiss the third amended complaint in the Westley action and the stay of discovery would remain in effect until further order of the Court or agreement by the parties, provided, however, that they obtain discovery produced in the Westley Action. By Order dated March 12, 2013, the parties to In re Oclaro, Inc. Derivative Litigation agreed to stay all proceedings until such time as (a) the defendants file an answer to any complaint in the Westley action; or (b) the Westley action is dismissed in its entirety with prejudice, provided, however, that they obtain discovery produced in the Westley Action. No trial has been scheduled in any of these actions.
On September 3, 2013, the parties agreed to settle the Westley, Moskal, and In re Oclaro Derivative matters for a total of $3.95 million, plus certain corporate governance changes. The money will be paid entirely by our directors and officers liability insurance carriers. Any fees awarded to the plaintiffs in these actions, or their respective counsel, are included in this amount. By Order dated August 13, 2014, the Court in the Westley matter gave its final approval to the settlement. Motions for final approval of the other settlements are pending.
Furukawa Patent Litigation
On May 27, 2011, Opnext Japan filed a complaint against Furukawa in the Tokyo District Court alleging that certain laser diode modules sold by Furukawa infringe Opnext Japan’s Japanese patent No. 3,887,174. Opnext Japan was seeking an injunction as well as damages in the amount of 100.0 million Japanese yen.
On August 5, 2011, Opnext Japan filed a complaint against Furukawa in the Tokyo District Court alleging that certain integratable tunable laser assemblies sold by Furukawa infringe Opnext Japan’s Japanese patent No. 4,124,845. Opnext Japan had sought an injunction as well as damages in the amount of 200.0 million Japanese yen.
On March 25, 2014, the outstanding patent litigation between Opnext Japan and Furukawa was settled by court recorded settlement before the Tokyo District Court on terms agreed to by both parties. In addition, Oclaro, Inc. and Furukawa entered into a separate out of court settlement agreement dated March 30, 2014.
Sale-Leasebacks
In May 2012, our Oclaro Technology (Shenzhen) Co., Ltd. subsidiary entered into an agreement with Shenzhen Fangdao Technology Co., Ltd. for the sale and leaseback of our manufacturing facility located in Shenzhen, China. On June 7, 2012, we completed the sale transaction for 136.0 million Chinese yuan (approximately $21.5 million at the exchange rate in effect on the date of the transaction). We received approximately $18.7 million in net proceeds after transfer taxes of approximately $2.5 million and transaction costs of approximately $0.4 million. This agreement also provides for Oclaro Technology (Shenzhen) Co., Ltd. to lease back the facility for a term of four years, provided that we may terminate the lease after the second or third year of the term upon written notice. Rental payments in fiscal years ended June 28, 2014 and June 29, 2013 were $1.2 million and $1.3 million, respectively. Annual rent for year three and year four of the lease is scheduled to increase 8 percent and 17 percent, respectively, from the rental rate during the first two years of the lease.
As a result of this transaction, we recorded a $13.6 million gain on the sale of this facility, recognizing $11.3 million of this amount in gain (loss) on sale of property and equipment in our consolidated statement of operations in fiscal year 2012, and amortizing $2.3 million of the gain against rent expense over the initial two year non-cancelable lease term. As of June 28, 2014, we had fully amortized the deferred gain.
In March 2006, our Oclaro Technology Ltd. subsidiary entered into multiple agreements with a subsidiary of Scarborough Development (Scarborough) for the sale and leaseback of the land and buildings located at our Caswell, U.K., manufacturing site. The sale transaction, which closed on March 30, 2006, resulted in proceeds to Oclaro Technology Ltd. of £13.75 million (approximately $24.0 million on the date of the transaction). Under these agreements, Oclaro Technology Ltd. leases back the Caswell site for an initial term of 20 years, with options to renew the lease term for 5 years following the initial term and for rolling 2-year terms thereafter. Based on the exchange rate on June 28, 2014, annual rent for the next 2 years of the lease is approximately £1.2 million, or $2.1 million per year; annual rent for the subsequent 5 years of the lease is approximately £1.4 million, or $2.4 million per year; and annual rent for the last 5 years of the lease is approximately £1.6 million, or $2.7 million per year. Rent during the optional renewal terms will be determined according to the then market rent for the site. The obligations of Oclaro Technology Ltd under these agreements are guaranteed by us. In addition, Scarborough and us entered into a pre-emption agreement with the buyer under which Oclaro Technology Ltd, within the initial 20-year term, has a right to purchase the Caswell site in whole or in part on terms acceptable to Scarborough if Scarborough agrees to terms with or receives an offer from a third party to purchase the Caswell facility. As a result of these agreements, we deferred a related gain of $20.4 million, which is being amortized ratably against rent expense over the initial 20-year term of the lease. As of June 28, 2014, the unamortized balance of this deferred gain is $11.7 million.
At the inception of the Caswell lease, we determined the total minimum lease payments which were to be paid over the lease term, and we are recognizing the effects of scheduled rent increases, which are included in the total minimum lease payments, on a straight-line basis over the lease term.

Equity [Abstract]	'
Stockholders' Equity	'
	STOCKHOLDERS’ EQUITY
	Common Stock
	On July 23, 2012, in connection with the Opnext acquisition, our stockholders approved an amendment to our restated certificate of incorporation to increase the number of authorized shares of Oclaro to 176.0 million, consisting of 175.0 million shares of common stock and 1.0 million shares of preferred stock.
	On May 2, 2014, PECM Strategic Funding L.P. and Providence TMT Debt Opportunity Fund L.P., holders of warrants (the “Warrants”) to purchase shares of our common stock, exercised the Warrants in full. We delivered 978,457 shares of our common stock in connection with the cashless exercise of the Warrants.
	On December 19, 2013, the holders of our convertible notes exercised their rights to exchange the convertible notes for our common stock. The exchange rate for the exchanges was 541.7118 shares of common stock per $1,000 in principal amount of convertible notes. We issued 13,542,791 shares of common stock in connection with the exchange, with cash payable in lieu of fractional shares.
	During fiscal year 2013, we issued approximately 38.4 million shares of our common stock for all of the outstanding shares of Opnext common stock. We also issued approximately 4.3 million stock options and 0.2 million SARs in exchange for Opnext stock options and SARs. The fair value of the stock options and SARs was determined to be approximately $1.9 million as of the acquisition date, July 23, 2012. See Note 3, Business Combinations and Dispositions.
	During the year ended June 29, 2013, we also issued 1.1 million shares of common stock under our 2011 Employee Stock Purchase Plan (ESPP) prior to suspending the ESPP program in the third quarter of fiscal year 2013, for total proceeds of $1.7 million. The ESPP is more fully discussed in Note 11, Employee Stock Plans.
	In connection with our acquisition of Mintera, during fiscal year 2012 we issued 0.8 million shares of our common stock valued at $2.8 million to settle our 12 months earnout obligation. The transfer of these shares resulted in a $2.8 million increase to our additional paid-in capital and a corresponding decrease to our accrued expenses and other liabilities.
	In connection with our acquisition of Xtellus Inc., during the first quarter of fiscal year 2012 we released 0.9 million shares of our common stock related to the settlement of our Xtellus escrow liability. The transfer of these shares resulted in a $7.0 million increase to our additional paid-in capital.
	Preferred Stock
	Our restated certificate of incorporation authorizes us to issue up to 1.0 million shares of preferred stock with designations, rights and preferences determined from time-to-time by our board of directors. To date, we have not issued any preferred stock.
	Warrants
	On May 6, 2013, we entered into Amendment Number Two to the Credit Agreement (refer to Note 7, Credit Line and Notes for further details), pursuant to which we issued warrants to purchase, in the aggregate, 1,836,000 shares of our common stock at an exercise price of $1.50 per share (subject to adjustment from time to time, as provided in the Warrants). The Warrants were issued by us in consideration of the Term Lenders entering into the Amendment and providing the Term Loan. The offer and sale of the Warrants was not registered under the Securities Act of 1933 in reliance upon the exemption from registration under Section 4(2) of the Securities Act as such transaction did not involve a public offering of securities. We also granted to the Term Lenders certain registration rights with respect to the Warrants.
	The warrants were valued using the Black-Scholes pricing model, which were determined to have a value of $0.7 million as of the date of grant. On May 2, 2014, the Term Lenders exercised their Warrants. We delivered 978,457 shares of our common stock in connection with the cashless exercise of the Warrants.

	EMPLOYEE STOCK PLANS
	Stock Incentive Plans
	In connection with our acquisition of Opnext, we assumed Opnext’s Third Amended and Restated 2001 Long-Term Stock Incentive Plan and the shares reserved for issuance thereunder. After giving effect to the exchange ratio, the unused and converted share reserve thereunder consisted of 6.3 million shares of common stock as of the acquisition date. Subject to compliance with applicable NASDAQ rules, we can only make grants to legacy Opnext employees and employees hired after the close of the merger unless stockholder approval was obtained to permit awards to all our employees. On July 23, 2013, our board of directors approved the Fourth Amended and Restated 2001 Long-Term Stock Incentive Plan (the "Plan") and on January 14, 2014, our shareholders ratified this plan, establishing it as our primary equity incentive plan. The Plan (i) revises the eligibility section to allow us to make grants to all our employees, non-employee directors and consultants, (ii) allows us to grant incentive stock options and awards which may be able to qualify as qualified performance-based compensation under Section 162(m) of the Internal Revenue Code, (iii) extends the term of the Plan to ten years from the effective date of the Plan (the Plan expires in July 2023), and (iv) conforms the share counting provisions of the Plan to provide that full value awards count as 1.25 shares for purposes of the Plan.
	We also maintain the Amended and Restated 2004 Stock Incentive Plan (“2004 Plan”). Under the 2004 Plan, there are a total of 7.8 million shares of common stock authorized for issuance, with full value awards being counted as 1.25 shares of common stock for purposes of the share limit. The 2004 Plan expires in October 2020.
	As of June 28, 2014, there were in aggregate 5.7 million shares of our common stock available for grant under the Fourth Amended and Restated 2001 Long-Term Incentive Plan and the Amended and Restated 2004 Stock Incentive Plan.
	We generally grant stock options that vest over a two to four year service period, and restricted stock awards and units that vest over a one to four year service period, and in certain cases each may vest earlier based upon the achievement of specific performance-based objectives as set by our board of directors or the compensation committee of our board of directors. We also have approximately 0.2 million SARs outstanding as of June 28, 2014, which we assumed in connection with our acquisition of Opnext. The SARs have an average remaining life of 1.2 years.
	In July 2011, our board of directors approved the grant of 0.2 million performance stock units (“PSUs”) to certain executive officers with an aggregate estimated grant date fair value of $0.9 million. These PSUs vest, up to 150 percent of the target PSUs, upon the achievement of certain revenue growth targets through June 30, 2013, relative to certain comparable companies. In October 2013, the board of directors determined that achievement of the performance conditions was reached at the 100 percent target level. Approximately 0.1 million of the grants outstanding, or 50 percent, vested on October 22, 2013, with the remaining 50 percent scheduled to vest upon a two-year service condition through August 2015. As of June 28, 2014, there were less than 0.1 million PSUs outstanding, after adjustments for forfeitures due to terminations, related to this grant, with an aggregate estimated grant date fair value of $0.2 million.
	In July 2012, our board of directors approved a grant of 0.6 million PSUs to certain executive officers, subject to shareholder approval of an amendment to our Plan. Prior to shareholder approval, approximately 0.4 million of the PSUs were forfeited as a result of certain executive officer departures. On January 14, 2014, shareholder approval was obtained at our annual general meeting of stockholders. In the third quarter of fiscal year 2014, the grant of 0.2 million PSUs became effective, with an aggregate estimated grant date fair value of $0.6 million. These PSUs vest upon the achievement of certain adjusted earnings before interest, taxes, depreciation and amortization targets through June 30, 2014. Vesting is also contingent upon service conditions being met through August 2016. If the performance conditions are not achieved, then the corresponding PSUs will be forfeited in the first quarter of fiscal year 2015. As of June 28, 2014, there were 0.2 million PSUs outstanding, after adjustments for forfeitures due to terminations, related to this grant, with an aggregate estimated grant date fair value of $0.4 million.
	In February 2014, our board of directors granted our chief executive officer 0.8 million restricted stock units ("RSUs") in satisfaction of the terms set forth in his employment agreement dated September 11, 2013. The RSUs vested in full on the date of grant, and settled on August 15, 2014. The RSUs have an aggregate grant date fair value of $2.0 million, which was recorded during fiscal year 2014.
	In March 2014, our board of directors approved a grant of 0.2 million PSUs to certain executive officers with an aggregate estimated grant date fair value of $0.5 million. These PSUs vest upon the achievement of non-GAAP operating income break-even for calendar year 2015. Vesting is also contingent upon service conditions being met through February 2018. If the performance condition is not achieved, then the corresponding PSUs will be forfeited in the third quarter of fiscal year 2016. As of June 28, 2014, there were 0.1 million PSUs outstanding, after adjustments for forfeitures due to terminations, related to this grant, with an aggregate estimated grant date fair value of $0.4 million.

	On October 26, 2011, our ESPP was approved by our stockholders. Under the ESPP, we reserved 1.7 million shares of our common stock for issuance. In the third quarter of fiscal 2013, prior to commencing our third six-month offering period on February 16, 2013, we suspended the ESPP program because of the limited number of shares available for future issuance. At June 28, 2014, we had 0.6 million shares available for future issuance under our ESPP.

Stock-Based Compensation	'
	STOCK-BASED COMPENSATION
	We recognize compensation expense in our statement of operations related to all share-based awards, including grants of stock options and purchase rights under our ESPP, based on the grant date fair value of such share-based awards. Estimating the grant date fair value of such share-based awards requires us to make judgments in the determination of inputs into the Black-Scholes stock option pricing model which we use to arrive at an estimate of the grant date fair value for such awards. This model requires assumptions to be made related to expected stock price volatility, expected option life, risk-free interest rate and dividend yield. While the risk-free interest rate is a less subjective assumption, typically based on factual data derived from public sources, the expected stock price volatility and option life assumptions require a greater level of judgment, which makes them critical accounting estimates. We have not issued and do not anticipate issuing dividends to stockholders and accordingly use a zero percent dividend yield assumption for all Black-Scholes stock option pricing calculations. We use an expected stock-price volatility assumption that is based on an implied and historical realized volatility of our underlying common stock during a period of time. With regard to the weighted-average option life assumption, we evaluate the exercise behavior of past grants and comparison to industry peer companies as a basis to predict future activity.
	The weighted-average assumptions used in this model to value stock option grants and purchase rights under the ESPP for the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012 were as follows:
		Year Ended
		June 28, 2014			June 29, 2013			June 30, 2012

	The amounts included in cost of revenues, operating expenses and net loss for stock-based compensation expenses for the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012 were as follows:

	As of June 28, 2014 and June 29, 2013, we capitalized $0.4 million and $0.4 million, respectively, of stock-based compensation in inventory.
	Included in stock-based compensation for the year ended June 28, 2014, is approximately $2.0 million in compensation cost related to the grant of 0.8 million RSUs to our chief executive officer on February 10, 2014, which vested in full on the grant date. Also included in stock-based compensation for the years ended June 28, 2014 and June 29, 2013, is approximately $0.1 million and $0.3 million, respectively, in compensation cost related to the issuance of PSUs from July 2011 and March 2014. The amount of stock-based compensation expense recognized in any one period related to PSUs can vary based on the achievement or anticipated achievement of the performance conditions. If the performance conditions are not met or not expected to be met, no compensation cost would be recognized on the underlying PSUs, and any previously recognized compensation expense related to those PSUs would be reversed. As of June 28, 2014, we determined that the achievement of the performance conditions associated with the PSUs issued in July 2012 are improbable. We have not recorded any compensation cost associated with these PSUs.
	As of June 28, 2014, we had $1.4 million in unrecognized stock-based compensation expense related to unvested stock options, net of estimated forfeitures, that will be recognized over a weighted-average period of 1.9 years, and $8.5 million in unrecognized stock-based compensation expense related to unvested restricted stock awards, net of estimated forfeitures, that will be recognized over a weighted-average period of 2.0 years.

	We have not provided for U.S. federal and state income taxes on non-U.S. subsidiaries’ undistributed earnings as of June 28, 2014 because we plan to indefinitely reinvest the unremitted earnings of our non-U.S. subsidiaries, except for our Shanghai, China; Korean; and Japanese entities, where closure will eventually follow our decision to exit certain businesses in fiscal year 2014. We recorded a tax liability of $0.3 million for the withholding taxes that would be owed upon distribution of these entities' earnings. Determination of the amount of unrecognized deferred U.S. income tax liability on unremitted earnings is not practicable due to the complexities associated with its hypothetical calculation.
	Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred tax assets are as follows:
		June 28, 2014			June 29, 2013

	Deferred tax assets:

	Total deferred tax liabilities	(4,416		)	(4,499		)
	Net deferred tax assets	$	(339	)	$	3,012
	Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. In evaluating our ability to recover deferred tax assets, we consider all available positive and negative evidence including past operating results, the existence of cumulative losses and our forecast of future taxable income. In determining future taxable income, we are responsible for assumptions utilized including the amount of state, federal and international pre-tax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we use to manage the underlying businesses.
	Recognition of deferred tax assets is appropriate when realization of these assets is more likely than not. Based upon the weight of available evidence, which includes our historical operating performance, the recorded cumulative net losses in prior fiscal periods and the uncertainty of the timing of future profits, we have provided a full valuation allowance against our U.S. and foreign deferred tax assets. Our valuation allowance decreased by $97.2 million, increased by $177.4 million and increased by $3.4 million for fiscal years 2014, 2013 and 2012, respectively.
	We have elected to derecognize both the gross deferred income tax assets and the offsetting valuation allowance pertaining to net operating loss and tax credit carryforwards that represent excess tax benefits from stock-based awards. Recognition of a deferred tax asset for excess tax benefits due to stock-based compensation deductions that have not yet been realized through a reduction in income taxes payable is prohibited. Such unrecognized deferred tax benefits totaled $3.3 million for federal and state as of June 28, 2014, and if and when realized through a reduction in income taxes payable, will be accounted for as a credit to additional paid-in capital.
	As of June 28, 2014, we had foreign net operating loss carry forwards of approximately $548.8 million, $168.6 million and $1.7 million in the United Kingdom, Japan and Israel, respectively. The United Kingdom and Israel net operating losses do not expire. The Japan net operating loss will expire at various times from 2018 through 2023. We also have U.S. federal and California net operating losses of approximately $205.8 million and $161.0 million, respectively, which will expire in various years from 2015 through 2034 if unused. As of June 28, 2014, we had U.S. federal, California and foreign research and development credits of approximately $0.1 million, $0.8 million and $1.5 million, respectively. The U.S. federal research credits will expire from 2019 through 2034. The California research credit may be carried forward indefinitely and the foreign credit will expire at various times from 2027 through 2032 if unused. In addition, we have foreign tax credits of approximately $1.4 million, which will expire from 2018 through 2024.
	Utilization of net operating loss carryforwards and credit carryforwards are subject to annual limitations due to ownership changes as provided in the Internal Revenue Code of 1986, as amended, as well as similar state and foreign tax laws. This annual limitation may result in the expiration of a significant portion of the net operating loss carry forwards and tax credits before utilization.
	Our total amount of unrecognized tax benefits as of June 28, 2014 was approximately $4.2 million. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $3.6 million as of June 28, 2014. While it is often difficult to predict the final outcome of any particular uncertain tax position, management believes unrecognized tax benefits could decrease by approximately $1.7 million in the next twelve months.
	A reconciliation of the beginning balance and the ending balance of gross unrecognized tax benefits, net of interest and penalties, for fiscal year ended June 28, 2014, June 29, 2013 and June 30, 2012 is as follows:
		Year Ended

Lapse of the applicable statute of limitations	(4,239		)	(158		)	—
Balance at end of period	$	4,164		$	8,016		$	7,248
We include interest and penalties related to unrecognized tax benefits within the provision for income taxes on our consolidated statements of operations. For fiscal years 2014, 2013 and 2012, we recognized $0.2 million, $0.3 million and $0.1 million, respectively, in interest and penalties related to unrecognized tax benefits. As of June 28, 2014 and June 29, 2013, we have accrued approximately $0.9 million and $0.7 million for payment of interest and penalties related to unrecognized tax benefits, respectively.
We file U.S. federal, U.S. state and foreign tax returns and have determined that our major tax jurisdictions are the United States, the United Kingdom, Italy, Japan and China. Certain jurisdictions remain open to examination by the appropriate governmental agencies; U.S. federal, Italy, Japan and China tax years 2008 to 2014, various U.S. states for tax years 2007 through 2014, and the United Kingdom tax years 2007 to 2014. In addition, in the U.S., any net operating loss and credit carryforwards may be subject to examination in the years they are utilized on the tax returns. We have currently been contacted for examination in Korea and Israel and we believe that our tax returns are supportable as filed. However, we cannot predict the outcome of the examination. We are not currently under any U.S., state, or other foreign examinations.

Earnings Per Share [Abstract]	'
Net Loss Per Share	'
	NET LOSS PER SHARE
	Basic net loss per share is computed using only the weighted-average number of shares of common stock outstanding for the applicable period, while diluted net income (loss) per share is computed assuming conversion of all potentially dilutive securities, such as stock options, stock appreciation rights, unvested restricted stock awards, warrants, shares issuable in connection with convertible notes and obligations under escrow agreements during such period. For fiscal years 2014, 2013 and 2012, we excluded such dilutive securities from the computation of diluted shares outstanding since we incurred a net loss from continuing operations in these periods which would have resulted in their inclusion having an anti-dilutive effect.
	For fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, we excluded 16.5 million, 17.5 million and 4.4 million, respectively, of outstanding stock options, stock appreciation rights, warrants, unvested restricted stock units or shares issuable in connection with convertible notes from the calculation of diluted net income (loss) per share because their effect would have been anti-dilutive.

(“Ushio Opto”) and Ushio, Inc. (“Ushio”), whereby Ushio Opto agreed to acquire the industrial and consumer business of Oclaro Japan located at its Komoro, Japan facility (the “Komoro Business”), by means of an absorption-type demerger under the Japanese Companies Act (such transaction, the “Transaction”). Consideration for the Transaction will consist of 1.85 billion Japanese yen (approximately $18.0 million based on the exchange rate on August 5, 2014) in cash, of which 1.6 billion Japanese yen (approximately $15.6 million based on the exchange rate on August 5, 2014) will be paid at the closing and 250 million Japanese yen (approximately $2.4 million) will be paid into escrow and released to Oclaro Japan upon the earlier of six months after the closing or the completion by Oclaro Japan of certain transition services, subject to a net asset valuation adjustment post-closing and after deduction for any indemnification amounts determined to be owed to Ushio Opto prior to release of the funds from escrow.
	At the closing of the Transaction, Oclaro Japan and Ushio Opto are expected to enter into certain transition services and reciprocal services agreements to allow the Komoro Business to continue operations during the ownership transition, as well as an intellectual property agreement. Consummation of the Transaction is subject to customary closing conditions. The closing of the Transaction is expected to occur during our second fiscal quarter of 2015 ending December 27, 2014. Ushio has guaranteed the performance of Ushio Opto’s obligations under the MSA.
	Oclaro Japan, Ushio Opto and Ushio each provided customary and reciprocal representations, warranties and covenants in the MSA.

Basis of Preparation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jun. 28, 2014
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Preparation
	The consolidated financial statements include the accounts of Oclaro and our subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), which contemplate the continuation of a company as a going concern. As of June 28, 2014, we held $104.1 million in cash and short-term investments, comprised of $99.0 million in cash and cash equivalents, $5.1 million in restricted cash and $0.1 million of short-term investments; and we had working capital of $175.2 million. We have incurred significant operating losses from continuing operations and generated negative cash flows from operations for fiscal year 2014. Recoverability of a major portion of the recorded asset amounts shown in the accompanying balance sheet is dependent upon us having sufficient resources to operate our business. In addition to the availability of our cash resources as of June 28, 2014, the continued operation of our business is dependent upon our achieving cash flows expected to be generated from the execution of our current operating plan, including anticipated restructuring plans, together with amounts expected to be available under our Credit Agreement and from the sale of our Komoro, Japan industrial and consumer business. See Note 17, Subsequent Events for further details on the sale of our Komoro, Japan industrial and consumer business. We can make no assurances that we will be successful concluding the sale of our Komoro, Japan industrial and consumer business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should we be unable to continue in existence.
	In the event that any of the sources of liquidity described in the preceding paragraph are, for any reason, not available to us in a timely manner or in the event that we need additional liquidity beyond our current expectations, such as to fund future growth or strengthen our balance sheet or to fund the cost of restructuring activities, we may find it necessary to lower our operating income break-even level and undertake additional cost cutting measures. We will continue to explore other sources of additional liquidity. These additional sources of liquidity could include one, or a combination, of the following: (i) issuing equity securities, (ii) incurring indebtedness secured by our assets, (iii) issuing debt and/or convertible debt securities, or (iv) selling product lines, other assets and/or portions of our business. There can be no guarantee that we will be able to raise additional funds on terms acceptable to us, or at all.
Reclassifications	'
	Reclassifications
	For presentation purposes, we have reclassified certain prior period amounts to conform to the current period financial statement presentation. These reclassifications did not affect our consolidated net income (loss), cash flows, cash and cash equivalents or stockholders’ equity as previously reported.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reported periods. Examples of significant estimates and assumptions made by management involve the fair value of goodwill and long-lived assets, the fair value of purchase consideration paid, assets acquired and liabilities assumed in business combinations, valuation allowances for deferred tax assets, the fair value of stock-based compensation, estimates used to determine facility lease loss liabilities, estimates for allowances for doubtful accounts, the evaluation of insurance recoveries, and valuation of excess and obsolete inventories. These judgments can be subjective and complex and consequently actual results could differ materially from those estimates and assumptions.
Fiscal Years	'
	Fiscal Years
	We operate on a 52/53 week year ending on the Saturday closest to June 30. Our fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012 were each 52 week years.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents are carried at market value. We consider all liquid investment securities with an original maturity date of three months or less to be cash equivalents. Any realized gains and losses on liquid investment securities are included in other income (expense) in our consolidated statements of operations.
	The following table provides details regarding our cash and cash equivalents at the dates indicated:
		June 28, 2014			June 29, 2013
		(Thousands)
	Cash and cash equivalents:
	Cash-in-bank	$	97,759		$	82,634
	Money market funds	1,214			2,001
		$	98,973		$	84,635
	As of June 28, 2014, $74.7 million of the $99.0 million of our cash and cash equivalents was held by our foreign subsidiaries. If these funds are needed for our operations in the United States, we could be required to accrue and pay U.S. taxes to repatriate these funds (subject to an adjustment for foreign tax credits).
	As of June 28, 2014, we also had restricted cash of $5.1 million, consisting of approximately $2.6 million which serves as collateral for the performance of our obligations under certain facility lease agreements and $2.4 million (equivalent to RMB 15 million) of cash held in Oclaro Shenzhen’s bank account in China that was frozen by the Xi'an Court in connection with our litigation with Xi’an Raysung Photonics Inc. (see Note 9, Commitments and Contingencies, for additional details regarding this litigation.)
Concentration of Credit Risks	'
	Concentration of Credit Risks
	We place our cash and cash equivalents with and in the custody of financial institutions, which at times, are in excess of amounts insured. Management monitors the ongoing creditworthiness of these institutions. Our investment policy limits the amounts invested with any one institution, type of security and issuer. To date, we have not experienced significant losses on these investments.
	Our trade accounts receivable are concentrated with companies in the telecom industry. At June 28, 2014, three customers accounted for a total of 42 percent of our gross accounts receivable. At June 29, 2013, three customers accounted for a total of 33 percent of our gross accounts receivable.
Allowance for Doubtful Accounts and Sales Return Allowance	'
	Allowance for Doubtful Accounts and Sales Return Allowance
	We perform ongoing credit evaluations of our customers and record specific allowances for doubtful accounts when a customer is unable to meet its financial obligations, as in the case of bankruptcy filings or deteriorated financial position. Estimates are used in determining allowances for customers based on factors such as current trends, the length of time the receivables are past due and historical collection experience. We write-off a receivable account when all rights, remedies and recourses against the account and its principals are exhausted and record a benefit when previously reserved accounts are collected. We recorded minimal provisions as allowances for doubtful accounts in fiscal year 2014 and $0.7 million and $0.1 million as allowances for doubtful accounts in fiscal years 2013 and 2012, respectively.
	We record a provision for estimated sales returns, which is netted against revenues, in the same period as the related revenues are recorded. These estimates are based on historical sales returns, other known factors and our return policy. In fiscal year 2014, 2013 and 2012, we recorded a provision of zero, $3.1 million and zero as sales return allowances, respectively.
Inventories	'
	Inventories
	Inventories, consisting of raw materials, work-in-process and finished goods are stated at the lower of cost (first in, first out basis) or market. We plan production based on orders received and a forecast demand. These production estimates are dependent on assessment of current and expected orders from our customers, including consideration that orders are subject to cancellation with limited advance notice prior to shipment. We assess the valuation of our inventory, including significant inventories held by contract manufacturers on our behalf, on a quarterly basis. Products may be unsalable because they are technically obsolete due to substitute products, specification changes or excess inventory relative to customer forecasts. We adjust the carrying value of inventory using methods that take these factors into account. If we find that the cost basis of our inventory is greater than the current market value, we write the inventory down to the estimated selling price, less the estimated costs to complete and sell the product.
Property and Equipment	'
	Property and Equipment
	Property and equipment are stated at cost. Depreciation is computed using the straight-line method based upon the estimated useful lives of the assets, which generally range from three to seven years. Leasehold improvements are amortized using the straight-line method over the estimated useful lives or the term of the related lease, whichever is shorter. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are removed from the accounts. Gains or losses resulting from asset dispositions are included in (gain) loss on sale of property and equipment in the accompanying consolidated statements of operations. Repair and maintenance costs are expensed as incurred.
	The following table provides details regarding our property and equipment, net at the dates indicated:
		June 28, 2014			June 29, 2013
		(Thousands)
	Property and equipment, net:
	Buildings and improvements	$	12,989		$	10,271
	Plant and machinery	47,247			72,144
	Fixtures, fittings and equipment	9,701			4,295
	Computer equipment	13,723			13,940
		83,660			100,650
	Less: accumulated depreciation	(32,892		)	(28,622		)
		$	50,768		$	72,028
	Depreciation expense was $25.3 million, $30.0 million and $12.9 million for the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, respectively. In fiscal year 2014, we recorded an impairment charge of $0.6 million related to the write-off of certain machinery that was not being utilized.
	Property and equipment includes assets under capital leases of $9.9 million and $18.2 million at June 28, 2014 and June 29, 2013, respectively, the majority of which were assumed in connection with the Opnext acquisition. Amortization associated with assets under capital leases is recorded in depreciation expense.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	We review our goodwill and other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable and also review goodwill annually. The values assigned to goodwill and other intangible assets are based on estimates and judgments regarding expectations for the success and life cycle of products and technologies acquired.
	In fiscal year 2013, our goodwill was tested for impairment using a two-step process. In the first step, the estimated fair value of a reporting unit is compared to its carrying value. If the fair value of a reporting unit exceeds the carrying value of the net assets assigned to a reporting unit, goodwill is considered not impaired and no further testing is required. If the carrying value of the net assets assigned to a reporting unit exceeds the fair value of a reporting unit, a second step of the impairment test is performed whereby we hypothetically apply purchase accounting to the reporting unit using the fair value from the first step in order to determine the implied fair value of a reporting unit’s goodwill. We estimate the fair value of the reporting unit using the expected present value of future cash flows and also compare our market capitalization plus a control premium for reasonableness. See Note 4. Goodwill and Other Intangible Assets.
	In fiscal year 2013, we adopted the Financial Accounting Standard Board's ("FASB") Accounting Standards Update ("ASU") 2012-2, Intangibles—Goodwill and Other (Topic 350)—Testing Indefinite-Lived Intangible Assets for Impairment, which established an optional two-step analysis for impairment testing of indefinite-lived intangibles other than goodwill. The two-step analysis establishes an optional qualitative assessment to precede our quantitative assessment, if necessary. In the qualitative assessment, we must evaluate the totality of qualitative factors, including any recent fair value measurements, that impact whether our indefinite-lived intangibles other than goodwill have a carrying amount that more likely than not exceeds their fair value.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	We review property and equipment and certain identifiable intangibles, excluding goodwill, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparing their carrying amounts to market prices or the future undiscounted cash flows the assets are expected to generate. If property and equipment or certain identifiable intangibles are considered to be impaired, the impairment to be recognized would equal the amount by which the carrying value of the asset exceeds its fair value based on market prices or future discounted cash flows.
	Intangible assets with definite lives are amortized over their estimated useful lives, which is generally from 1 to 11.5 years and 15 years as to one specific customer contract.
Non-Marketable Cost Method Investments	'
	Non-Marketable Cost Method Investments
	We account for our non-marketable cost method investments, which consist of less than 20 percent equity ownership interests of common stock and/or preferred stock in privately-held companies, under the cost method of accounting. As of June 28, 2014 and June 29, 2013, we no longer held any investments in privately-held companies. During fiscal year 2013, we sold our remaining cost method investment for $3.9 million of cash proceeds. We had previously acquired this investment in fiscal year 2010 for a purchase price of $7.5 million. We recorded a $3.6 million impairment charge during fiscal year 2013 in other income (expense) in our consolidated statement of operations.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	Our operating results are subject to fluctuations based upon changes in the exchange rates between the currencies in which we collect revenues and pay expenses. A majority of our revenues are denominated in U.S. dollars, while a significant portion of our expenses are denominated in United Kingdom (U.K.) pounds sterling, Japanese yen, Chinese yuan and euros, in which we pay expenses in connection with operating our facilities in the United Kingdom, Japan, China and Italy. Prior to our sale of our Zurich Business, we also incurred a significant portion of our expenses in Swiss francs. Historically, we have entered into foreign currency forward exchange contracts in an effort to mitigate a portion of our exposure to exchange rate fluctuations between the U.S. dollar and the U.K. pound sterling.
	We recognize all derivatives, such as foreign currency forward exchange contracts, on our consolidated balance sheets at fair value regardless of the purpose for holding the instrument. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through operating results or recognized in accumulated other comprehensive income until the hedged item is recognized in operating results in our consolidated statements of operations.
	At June 28, 2014 and June 29, 2013, we had no outstanding foreign currency forward exchange contracts.
Warranty	'
	Warranty
	We generally provide a warranty for our products ranging from 12 months to 36 months from the date of sale, although warranties for certain of our products may be longer. We accrue for the estimated costs to provide warranty services at the time revenue is recognized. Our estimate of costs to service our warranty obligations is based on historical experience and expectation of future conditions. To the extent we experience increased warranty claim activity or increased costs associated with servicing those claims, our warranty costs would increase, resulting in a decrease in gross profit.
Revenue Recognition	'
	Revenue Recognition
	We recognize product revenue when (i) persuasive evidence of an arrangement exists, (ii) the product has been shipped and title has transferred, (iii) collectability is reasonably assured, (iv) the fees are fixed or determinable and (v) there are no uncertainties with respect to customer acceptance. We record a provision for estimated sales returns in the same period as the related revenues are recorded, which is netted against revenue. These estimates are based on historical sales returns, other known factors and our return policy.
Research and Development Costs	'
	Research and Development Costs
	Research and development costs are expensed as incurred.
Advertising Costs	'
	Advertising Costs
	Advertising costs are expensed as incurred. Our advertising costs for the years ended June 28, 2014, June 29, 2013 and June 30, 2012 were not significant.
Restructuring Expenses	'
	Restructuring Expenses
	We record costs associated with employee terminations and other exit activities when the liability is incurred. Employee termination benefits are recorded when the benefit arrangement is communicated to the employee and no significant future services are required. If employees are required to render service until they are terminated in order to receive the termination benefits, the fair value of the termination date liability is recognized ratably over the future service period. Lease cancellation and commitment costs are recorded when we cease using the facility. Lease cancellation and commitment costs are calculated using estimated future lease commitments less estimated sublease income, based on current market conditions. See Note 5, Restructuring Liabilities.
Insurance Recoveries	'
	Insurance Recoveries
	Insurance recoveries related to impairment losses previously recorded and other recoverable expenses will be recognized up to the amount of our related loss or expense in the period that recoveries become realizable. Insurance recoveries under business interruption coverage and insurance recovery gains in excess of amounts previously written off related to impaired inventory and equipment or in excess of other recoverable expenses previously recognized will be recognized when they become realizable and all contingencies have been resolved.
	During the year ended June 28, 2014 and June 29, 2013, we received $3.7 million and $30.8 million in settlement payments, respectively, relating to losses we incurred due to flooding at our contract manufacturer in Thailand. As there were no contingencies associated with these payments, we recorded these payments within flood-related (income) expense, net in our consolidated statements of operations for the year ended June 28, 2014 and June 29, 2013, respectively.
	The evaluation of insurance recoveries requires estimates and judgments about future results which affect reported amounts and certain disclosures. Actual results could differ from those estimates.
Stock-Based Compensation	'
	Stock-Based Compensation
	We use the Black-Scholes option pricing model to value the fair value of stock options, purchase rights under our employee stock purchase program and stock appreciation rights. We use grant date fair value to value restricted stock awards, restricted stock units and performance shares.
	We record compensation expense using the straight-line method and estimate forfeitures when recognizing compensation expense, and we adjust our estimate of forfeitures over the requisite service period based on the extent to which actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of compensation expense to be recognized in future periods. The amount of stock-based compensation expense recognized in any one period related to performance shares can vary based on the achievement or anticipated achievement of the performance conditions. If the performance conditions are not met or not expected to be met, no compensation cost would be recognized on the underlying performance shares, and any previously recognized compensation expense related to those performance shares would be reversed.
	Stock options have a term of seven to ten years and generally vest over a two to four year service period, and restricted stock awards generally vest over a one to four year service period, and in certain cases each may vest earlier based upon the achievement of specific performance-based objectives as set by our board of directors or may be subject to additional vesting conditions based upon achievement of such performance-based objectives.
Foreign Currency Transactions and Translation Gains and Losses	'
	Foreign Currency Transactions and Translation Gains and Losses
	The assets and liabilities of our foreign operations are translated from their respective functional (local) currencies into U.S. dollars at the rates in effect at the consolidated balance sheet dates, and revenue and expense amounts are translated at the average rate during the applicable periods reflected on the consolidated statements of operations. Foreign currency translation adjustments are recorded as accumulated other comprehensive income, except for the translation adjustment of short-term intercompany loans or payables which are recorded as gain (loss) on foreign currency transactions in our consolidated statements of operations. Gains and losses from foreign currency transactions, realized and unrealized in the event of foreign currency transactions not designated as hedges, and those transactions denominated in currencies other than our functional currency, are recorded as gain (loss) on foreign currency transactions in our consolidated statements of operations.
Income Taxes	'
	Income Taxes
	We account for income taxes using an asset and liability based approach. Deferred income tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. Valuation allowances are provided against deferred income tax assets which are not likely to be realized.
Net Income (Loss) Per Share	'
	Net Income (Loss) Per Share
	Basic net income (loss) per share is computed using only the weighted-average number of shares of common stock outstanding for the applicable period, while diluted net income (loss) per share is computed assuming conversion of all potentially dilutive securities, such as stock options, stock appreciation rights, unvested restricted stock awards, warrants, shares issuable in connection with convertible notes and obligations under escrow agreements during such period. For the fiscal years ended June 28, 2014, June 29, 2013 and June 30, 2012, we excluded such dilutive securities from the computation of diluted shares outstanding since we incurred a net loss from continuing operations in these periods and their inclusion would have an anti-dilutive effect.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In March 2013, the FASB issued ASU No. 2013-5, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. This guidance amends a parent company’s accounting for the cumulative translation adjustment recorded in accumulated other comprehensive income associated with a foreign entity. The amendment requires a parent to release into net income the cumulative translation adjustment related to its investment in a foreign entity when it either sells a part or all of its investment, or no longer holds a controlling financial interest in a subsidiary or group of assets within a foreign entity. We elected to early adopt this guidance during our first quarter of fiscal year 2014. Accordingly, we treated our sale of our Zurich Business in the first quarter of fiscal year 2014 in accordance with this guidance and recorded $3.1 million in income from discontinued operations related to the cumulative translation adjustment from deconsolidating our Swiss subsidiary during the year ended June 28, 2014 within the consolidated statement of operations. This guidance will continue to impact our financial position and results of operations prospectively in the instance of an event or transaction described above.
	In July 2013, the FASB issued amended guidance that resolves the diversity in practice for the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This new accounting guidance requires the netting of unrecognized tax benefits ("UTBs") against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. Under the new standard, UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. The new standard requires prospective adoption but allows retrospective adoption for all periods presented. We have adopted this guidance during our second quarter of fiscal year 2014. The adoption of the guidance did not have a significant impact on our financial position, results of operations or cash flows.
	In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This update requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity's financial results or a business activity classified as held for sale should be reported as discontinued operations. The standard also expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not meet the definition of a discontinued operation. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2014. This guidance is effective for us prospectively in the third quarter of fiscal year 2015. We do not expect these changes to have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The FASB issued ASU 2014-09 to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016. This guidance is effective for us prospectively in the first quarter of fiscal year 2018. We are currently evaluating the impact that the implementation of this standard will have on our financial statements.

Quarterly Financial Information Disclosure [Abstract]	'
Quarterly Consolidated Financial Data	'
	The following tables set forth our unaudited condensed consolidated statements of operations data for each of the eight quarterly periods ended June 28, 2014. We have prepared this unaudited information on a basis consistent with our audited consolidated financial statements, reflecting all normal recurring adjustments that we consider necessary for a fair presentation of our financial position and operating results for the fiscal quarters presented. Basic and diluted net loss per share is computed independently for each of the quarters presented. Therefore, the sum of quarterly basic and diluted per share information may not equal annual basic and diluted net income (loss) per share.
	On September 12, 2013 and November 1, 2013, we sold our Zurich and Amplifier Businesses, respectively. These sales are reported as discontinued operations, which require retrospective restatement of prior periods to classify the results of operations as discontinued operations.
