Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1. Basis of Presentation The financial information for Viavi Solutions Inc. (“Viavi” also referred to as “the Company”, “we”, “our” and “us”) as of January 2, 2016 and for the three and six months ended January 2, 2016 and December 27, 2014 is unaudited, and includes all normal and recurring adjustments Company management (“Management”) considers necessary for a fair statement of the financial information set forth herein, in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, such information does not include all of the information and footnotes required by U.S. GAAP for annual financial statements. For further information, please refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 27, 2015 . The balance sheet as of June 27, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The results for the three and six months ended January 2, 2016 and December 27, 2014 may not be indicative of results for the year ending July 2, 2016 or any future periods. Fiscal Years The Company utilizes a 52 - 53 week fiscal year ending on the Saturday closest to June 30th. The Company’s fiscal 2016 is a 53 -week year ending on July 2, 2016 . The Company’s fiscal 2015 was a 52 -week year ending on June 27, 2015 . Lumentum Separation On August 1, 2015 (the “Separation Date”), Viavi, formerly known as JDS Uniphase Corporation (“JDSU”), completed the distribution of approximately 80.1% of the outstanding shares of Lumentum Holdings Inc. (“Lumentum”) common stock (the “Distribution”). Concurrent with the Distribution, JDSU was renamed Viavi Solutions Inc. and, at the time of the Distribution, retained ownership of approximately 19.9% of Lumentum’s outstanding shares. Lumentum was formed to hold Viavi’s communications and commercial optical products business segment (“CCOP”) and the WaveReady product line and, as a result of the Distribution, is now an independent public company trading under the symbol “LITE” on The Nasdaq Stock Market (“NASDAQ”). The Distribution was made to Viavi’s stockholders of record as of the close of business on July 27, 2015 (the “Record Date”), who received one share of Lumentum common stock for every five shares of Viavi common stock held as of the close of business on the Record Date and not sold prior to August 4, 2015, the ex-dividend date. The historical results of operations and the financial position have been recasted to present the Lumentum business as discontinued operations as described in “ Note 3. Discontinued Operations .” Unless noted otherwise, discussion in the Notes to Consolidated Financial Statements pertain to continuing operations. Principles of Consolidation The amounts presented in the consolidated financial statements have been prepared in accordance with U.S. GAAP and include the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, the reported amount of Net revenues and expenses and the disclosure of commitments and contingencies during the reporting periods. The Company bases estimates on historical experience and on various assumptions about the future believed to be reasonable based on available information. The Company’s reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Note 2. Recently Issued Accounting Pronouncements In January 2016, the FASB (“Financial Accounting Standards Board”) issued guidance that requires an entity to measure equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, it requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset. It also eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The guidance is effective for the company in the first quarter of fiscal 2019. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In November 2015, the FASB issued guidance requiring deferred tax assets and liabilities, and any related valuation allowance, to be classified as non-current on the balance sheet. This classification eliminates the need to separately identify the net current and net non-current deferred tax asset or liability in each jurisdiction. The Company elected to prospectively adopt the guidance in the beginning of the second quarter of fiscal 2016. Refer to “ Note 12. Income Taxes ” for more information regarding the impact of adopting this guidance. In July 2015, the FASB issued guidance to change the subsequent measurement of inventory from lower of cost or market to lower of cost and net realizable value. The guidance is effective for the Company in the first quarter of fiscal 2018. Earlier application is permitted as of the beginning of an interim or annual reporting period. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In May 2015, the FASB issued guidance to remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using net asset value per share practical expedient. The guidance is effective for the Company in the first quarter of fiscal 2017 and may apply to certain pension assets. The guidance will be applied retrospectively and earlier adoption is permitted. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In April 2015, the FASB issued new authoritative guidance to provide a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. Prospective application is required and early adoption is permitted. This guidance is effective for the Company in the first quarter of fiscal 2017 and may apply to the qualified and the non-qualified pension plans in certain countries. The Company will not early adopt and is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In April 2015, the FASB issued new authoritative guidance to simplify the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding liability, consistent with debt discounts or premiums. This guidance is effective for the Company in the first quarter of fiscal 2017 for its convertible debt, and will be applied retrospectively. The consolidated balance sheet of each individual period presented will be adjusted to reflect the period-specific effects of applying this new guidance. In May 2014, the FASB issued new authoritative guidance related to revenue recognition. This guidance will replace current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. The new revenue recognition guidance provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance allows for either full retrospective adoption or modified retrospective adoption. The FASB deferred the effective date for this guidance by one year to December 15, 2017 for annual reporting periods beginning after such date. Earlier application of this guidance is permitted but not before the original date of December 15, 2016. The guidance is effective for the company in the first quarter of fiscal 2019. The Company is evaluating the impact that this new accounting guidance will have on its consolidated financial statements and related disclosures.

Discontinued Operations

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Note 3. Discontinued Operations On August 1, 2015, the Company completed the separation of the Lumentum business (the “Separation”) and made a tax-free distribution of approximately 80.1% of the outstanding shares of Lumentum common stock to Viavi shareholders who received one share of Lumentum common stock for every five shares of Viavi common stock held as of the close of business on July 27, 2015 (the “Record Date”) and not sold prior to August 4, 2015 (the “ex-dividend date”). In connection with the Separation Viavi agreed to contribute $137.6 million of total cash, of which $0.9 million remains to be contributed as of January 2, 2016 . As of the Distribution, Viavi retained ownership of approximately 19.9% , or 11.7 million shares, of Lumentum’s outstanding shares. Lumentum was formed to hold Viavi’s CCOP business and the Waveready product line. As a result of the Distribution, Lumentum is now an independent public company. In connection with the Separation, the Company entered into a Contribution Agreement, Separation and Distribution Agreement, a Tax Matters Agreement, Employee Matters Agreement, Securities Purchase Agreement, a Supply Agreement, and an Intellectual Property Matters Agreement with Lumentum and others. The Contribution Agreement identifies the assets to be transferred, the liabilities to be assumed and the contracts to be assigned and it provides for when and how these transfers, assumptions and assignments will occur. The Separation and Distribution Agreement governs the separation of the CCOP and Waveready business, the transfer of assets and other matters related to Viavi’s relationship with Lumentum. The Tax Matters Agreement governs the respective rights, responsibilities and obligations of Lumentum and Viavi with respect to tax liabilities and benefits, tax attributes, tax contests, tax returns, and certain other tax matters. The Employee Matters Agreement governs the compensation and employee benefit obligations with respect to the current and former employees and non-employee directors of Lumentum and Viavi, and generally allocates liabilities and responsibilities relating to employee compensation, benefit plans and programs. The Employee Matters Agreement provides that employees of Lumentum will no longer participate in benefit plans sponsored or maintained by Viavi. The Securities Purchase Agreement with the Company, Lumentum and Amada Holdings Co., Ltd. (“Amada”) set forth terms whereby the Company received 40,000 shares of Lumentum’s Series A Preferred Stock (“Series A Preferred Stock”) pursuant to a binding commitment to sell the Series A Preferred Stock to Amada following the Separation. Upon Separation, in connection with the agreement, during the first quarter of fiscal 2016 the Company sold 35,805 shares of the Series A Preferred Stock to Amada for $35.8 million and the remaining 4,195 shares of the Series A Preferred Stock were canceled. The $35.8 million is included as a part of financing activities in the Statement of Cash Flows. The Supply Agreement outlines that Viavi will supply test equipment to Lumentum and Lumentum will supply components related to the Company’s metro, fiber and optical product lines and development services related to smart transceivers. The most significant component of the Supply Agreement is $15 million related to the sale of certain optical test equipment to Lumentum during the 12 month period from the date of the agreement through July 31, 2016, of which the company recorded $3.8 million and $8.3 million of net revenue during the three and six months ended January 2, 2016 , respectively. The Intellectual Property Matters Agreement outlines the intellectual property rights and technology transferred to Lumentum upon the Separation, as well as the intellectual property and technology both companies can license from each other. In addition it outlines non-compete restrictions between Viavi and Lumentum. As the separation of the Lumentum business represents a strategic shift that has and will have a major effect on the Company’s operations and financial results, the results of operations and net assets of the Lumentum business are presented separately as discontinued operations for the three and six months ended January 2, 2016 and December 27, 2014 and as of June 27, 2015, in accordance with the authoritative guidance. Lumentum is now a stand-alone public company that separately reports it financial results. Due to the difference between the basis of presentation for discontinued operations and the basis of presentation as a stand-alone company, the financial results of Lumentum included within discontinued operations for the Company may not be indicative of actual financial results of Lumentum as a stand-alone company. The following table presents the carrying amounts of the major classes of the assets and liabilities of the Lumentum business which are presented as discontinued operation on the Consolidated Balance Sheets (in millions) . June 27, 2015 Assets: Cash and cash equivalents $ 13.4 Accounts receivable, net 150.2 Inventories, net 100.0 Prepayments and other current assets 46.6 Current assets of discontinued operations 310.2 Property, plant and equipment, net 145.4 Goodwill 5.6 Intangibles, net 21.8 Other non-current assets 31.4 Non-current assets of discontinued operations 204.2 Total assets of discontinued operations $ 514.4 Liabilities: Accounts payable $ 79.1 Accrued payroll and related expenses 18.3 Income taxes payable 3.7 Accrued expenses 17.5 Other current liabilities 11.4 Current liabilities of discontinued operations 130.0 Non-current liabilities of discontinued operations 10.9 Total liabilities of discontinued operations $ 140.9 In connection with the Separation, $7.8 million of accumulated other comprehensive loss, net of income taxes, related to foreign currency translation adjustments and the pension plan obligation was transferred to Lumentum on the Separation Date. Refer to “ Note 5. Accumulated Other Comprehensive (Loss) Income ” for more information. The Company also transferred deferred tax assets of $29.5 million , deferred tax liabilities of $1.0 million , current income tax payables of $3.3 million , an income tax receivable of $1.3 million and other long-term liabilities related to uncertain tax positions totaling $0.1 million on the Separation date. The Company utilized approximately $1.0 billion of federal net operating losses to offset income recognized as a result of the Separation and the license of Lumentum’s intellectual property to a foreign subsidiary. The removal of Lumentum’s net assets and equity related adjustments upon the Separation are presented as an increase of Viavi's accumulated deficit and represents a non-cash financing activity, excluding the cash transferred. Refer to “ Note 14. Stock-Based Compensation ” for information on modifications to stock-based compensation awards as a result of the Distribution. The following table summarizes results from discontinued operations of the Lumentum business included in the condensed Consolidated Statement of Operations (in millions) : Three Months Ended (1) Six Months Ended December 27, 2014 January 2, 2016 December 27, 2014 Net revenues $ 210.7 $ 66.5 $ 429.0 Cost of revenues 141.4 49.7 287.4 Amortization of acquired technologies 1.9 0.6 3.8 Gross profit 67.4 16.2 137.8 Operating expenses: Research and development 35.0 12.5 69.8 Selling, general and administrative 18.8 24.0 36.0 Restructuring charges 0.6 0.1 2.4 Total operating expenses 54.4 36.6 108.2 (Loss) income from operations 13.0 (20.4 ) 29.6 Interest and other income (expense), net (0.1 ) 0.5 (0.3 ) (Loss) income before income taxes 12.9 (19.9 ) 29.3 Income tax provision 0.3 30.5 0.6 Net (loss) income from discontinued operations $ 12.6 $ (50.4 ) $ 28.7 (1) Net income from discontinued operations for the three months ended January 2, 2016 of $3.0 million is comprised of costs to complete the separation offset by a benefit from income taxes from discontinued operations of $4.5 million . No income or expense relating to the Lumentum business has been recorded after the separation from Viavi on August 1, 2015. During the six months ended January 2, 2016 , the income tax provision for discontinued operation of $30.5 million , included approximately $5.6 million of cash taxes that are due to federal and state authorities as a result of the Separation. In addition, approximately $25.2 million of the income tax provision for discontinued operations related to the income tax intraperiod tax allocation rules in relation to continuing operations and other comprehensive income. Net (loss) income from discontinued operations also includes costs incurred by the Company to separate Lumentum such as transaction charges, advisory and consulting fees. Net income (loss) from discontinued operations for the three and six months ended January 2, 2016 included $1.5 million and $15.5 million of costs to complete the separation, respectively.

Investments and Fair Value Measurements
Investments and Fair Value Measurements	Note 7. Investments and Fair Value Measurements The Company’s investments in marketable debt and equity securities were primarily classified as available-for-sale securities. As of January 2, 2016 , the Company’s available-for-sale securities were as follows ( in millions ): Amortized Cost/Carrying Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Debt securities: U.S. treasuries $ 46.3 $ — $ — $ 46.3 U.S. agencies 59.7 — (0.1 ) 59.6 Municipal bonds and sovereign debt instruments 2.3 — — 2.3 Asset-backed securities 49.8 — (0.4 ) 49.4 Corporate securities 183.8 — (0.2 ) 183.6 Total debt securities 341.9 — (0.7 ) 341.2 Marketable equity securities 100.3 157.2 — 257.5 Total available-for-sale securities $ 442.2 $ 157.2 $ (0.7 ) $ 598.7 The Company generally classifies debt securities as cash equivalents, short-term investments or other non-current assets based on the stated maturities; however, certain securities with stated maturities of longer than twelve months which are highly liquid and available to support current operations are also classified as short-term investments. As of January 2, 2016 , of the total fair value, $15.8 million was classified as cash equivalents, $324.7 million was classified as short-term investments and $0.7 million was classified as other non-current assets. Marketable equity securities consist of the Company’s ownership of 11.7 million shares of Lumentum common stock retained in connection with the Separation. These securities are stated at fair value, with unrealized gains and losses reported in other comprehensive income, net of tax and are classified as short-term investments on the Consolidated Balance Sheet as of January 2, 2016 at $257.5 million . The Company has not recognized any realized gains or losses related to these securities.

Trading securities are reported at fair value, with the unrealized gains or losses resulting from changes in fair value recognized in Interest and other income (expense), net. During the three and six months ended January 2, 2016 and December 27, 2014 , the Company recorded no other-than-temporary impairment charges in each respective period. As of January 2, 2016 , contractual maturities of the Company’s debt securities classified as available-for-sale securities were as follows ( in millions ): Amortized Cost/Carrying Cost Estimated Fair Value Amounts maturing in less than 1 year $ 233.9 $ 233.8 Amounts maturing in 1 - 5 years 105.5 105.3 Amounts maturing in more than 5 years 2.5 2.1 Total debt available-for-sale securities $ 341.9 $ 341.2 As of June 27, 2015 , the Company’s available-for-sale securities were as follows ( in millions ): Amortized Cost/Carrying Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Debt securities: U.S. treasuries $ 51.9 $ — $ — $ 51.9 U.S. agencies 96.0 — — 96.0 Municipal bonds and sovereign debt instruments 4.0 — — 4.0 Asset-backed securities 70.6 — (0.2 ) 70.4 Corporate securities 274.1 0.1 (0.1 ) 274.1 Total debt available-for-sale securities $ 496.6 $ 0.1 $ (0.3 ) $ 496.4 As of June 27, 2015 , of the total fair value, $33.7 million was classified as cash equivalents, $461.9 million was classified as short-term investments and $0.8 million was classified as other non-current assets.

Trading securities are reported at fair value, with the unrealized gains or losses resulting from changes in fair value recognized in Interest and other income (expense), net. Fair Value Measurements Assets measured at fair value as of January 2, 2016 are summarized below ( in millions ): Fair value measurement as of January 2, 2016 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Assets: Debt available-for-sale securities U.S. treasuries $ 46.3 $ 46.3 $ — U.S. agencies 59.6 — 59.6 Municipal bonds and sovereign debt instruments 2.3 — 2.3 Asset-backed securities 49.4 — 49.4 Corporate securities 183.6 — 183.6 Total debt available-for-sale securities 341.2 46.3 294.9 Marketable equity securities 257.5 257.5 — Money market funds 203.0 203.0 — Trading securities 3.3 3.3 — Total assets (1) $ 805.0 $ 510.1 $ 294.9 (1) $ 204.5 million in cash and cash equivalents, $585.5 million in short-term investments, $10.5 million in restricted cash, and $4.5 million in other non-current assets on the Company’s Consolidated Balance Sheets. Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. There is an established hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the assumptions about the factors that market participants would use in valuing the asset or liability. The Company’s cash and investment instruments are classified within Level 1 or Level 2 of the fair value hierarchy based on quoted prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. • Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets. Level 1 assets of the Company include money market funds, U.S. Treasury securities and marketable equity securities as they are traded with sufficient volume and frequency of transactions. • Level 2 includes financial instruments for which the valuations are based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities. Level 2 instruments of the Company generally include certain U.S. and foreign government and agency securities, commercial paper, corporate and municipal bonds and notes, asset-backed securities, and foreign currency forward contracts. To estimate their fair value, the Company utilizes pricing models based on market data. The significant inputs for the valuation model usually include benchmark yields, reported trades, broker and dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, and industry and economic events. • Level 3 includes financial instruments for which fair value is derived from valuation based on inputs that are unobservable and significant to the overall fair value measurement. As of June 27, 2015 and during the three and six months ended January 2, 2016 and December 27, 2014 the Company did not hold any Level 3 investment securities. Foreign Currency Forward Contracts The Company has foreign subsidiaries that operate and sell the Company’s products in various markets around the world. As a result, the Company is exposed to foreign exchange risks. The Company utilizes foreign exchange forward contracts and other instruments to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily certain short-term intercompany receivables and payables, and to reduce the volatility of earnings and cash flows related to foreign-currency transactions. The forward contracts, most with a term of less than 120 days, were transacted near quarter end; therefore, the fair value of the contracts as of both January 2, 2016 and June 27, 2015 is not material. The change in the fair value of these foreign currency forward contracts is recorded as gain or loss in the Company’s Consolidated Statements of Operations as a component of Interest and other income (expense), net.

Debts and Letters of Credit	Note 10. Debts and Letters of Credit As of January 2, 2016 and June 27, 2015 , the Company’s long-term debt on the Consolidated Balance Sheets represented the carrying amount of the liability component of the 0.625% Senior Convertible Notes as discussed below. The following table presents the carrying amounts of the liability and equity components ( in millions ): January 2, 2016 June 27, 2015 Principal amount of 0.625% Senior Convertible Notes $ 650.0 $ 650.0 Unamortized discount of liability component (75.2 ) (88.4 ) Carrying amount of liability component $ 574.8 $ 561.6 Carrying amount of equity component (1) $ 134.4 $ 134.4 (1) Included in Accumulated paid-in-capital on the Consolidated Balance Sheets. The Company was in compliance with all debt covenants and held no short term debt as of January 2, 2016 and June 27, 2015 . 0.625% Senior Convertible Notes On August 21, 2013, the Company issued $650.0 million aggregate principal amount of 0.625% Senior Convertible Notes due 2033 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The proceeds from the 2033 Notes amounted to $636.3 million after issuance costs. The 2033 Notes are an unsecured obligation of the Company and bear interest at an annual rate of 0.625% payable in cash semi-annually in arrears on February 15 and August 15 of each year. The 2033 Notes mature on August 15, 2033 unless earlier converted, redeemed or repurchased. The 2033 Notes and its terms are described in “Note 10. Debts and Letters of Credit” of the Company’s Annual Report on Form 10-K for the year ended June 27, 2015. Following the separation of the Lumentum business on August 1, 2015, the conversion price per share was adjusted pursuant to the terms of the 2033 Notes relating to the occurrence of a spin-off event. Effective as of the end of the business day on August 17, 2015, the initial conversion price per share was adjusted to $11.28 per share of the Company’s common stock traded on NASDAQ under the ticker symbol “VIAV.” In accordance with the authoritative accounting guidance, the Company separated the 2033 Notes into liability and equity components. The carrying value of the liability component at issuance was calculated as the present value of its cash flows using a discount rate of 5.4% based on the 5 -year swap rate plus credit spread as of the issuance date. The credit spread for the Company is based on the historical average “yield to worst” rate for BB rated issuers. The difference between the 2033 Notes principal and the carrying value of the liability component, representing the value of conversion premium assigned to the equity component, was recorded as a debt discount on the issuance date and is being accreted using the effective interest rate of 5.4% over the period from the issuance date through August 15, 2018 as a non-cash charge to interest expense. The carrying value of the liability component was determined to be $515.6 million , and the equity component, or debt discount, of the 2033 Notes was determined to be $134.4 million . As of January 2, 2016 , the expected remaining term of the 2033 Notes is 2.6 years. In connection with the issuance of the 2033 Notes, the Company incurred $13.7 million of issuance costs, which were bifurcated into the debt issuance costs, attributable to the liability component of $10.9 million and the equity issuance costs, attributable to the equity component of $2.8 million based on their relative values. The debt issuance costs were capitalized and are being amortized to interest expense using the effective interest rate method from issuance date through August 15, 2018. The equity issuance costs were netted against the equity component in additional paid-in capital at the issuance date. As of January 2, 2016 , the unamortized portion of the debt issuance costs related to the 2033 Notes was $6.1 million , which was included in Other non-current assets on the Consolidated Balance Sheets. Based on quoted market prices as of January 2, 2016 and June 27, 2015 , the fair value of the 2033 Notes was approximately $610.1 million and $644.0 million . The 2033 Notes are classified within Level 2 as they are not actively traded in markets. The following table presents the effective interest rate and the interest expense for the contractual interest and the accretion of debt discount ( in millions, except for the effective interest rate ): Three Months Ended Six Months Ended January 2, 2016 December 27, 2014 January 2, 2016 December 27, 2014 Effective interest rate 5.4 % 5.4 % 5.4 % 5.4 % Interest expense-contractual interest $ 1.0 $ 1.0 $ 2.0 $ 2.0 Accretion of debt discount 6.6 6.3 13.2 12.5 Outstanding Letters of Credit As of January 2, 2016 , the Company had 10 standby letters of credit totaling $14.3 million .

Payments related to the Germantown lease costs are expected to be paid by the end of the second quarter of fiscal 2019. Central Finance and Information Technology (“IT”) Restructuring Plan During the second quarter of fiscal 2014, Management approved a plan to eliminate positions and re-define roles and responsibilities in the Finance and IT organization to align with the future state of the organizations under new executive management and move positions to lower-cost locations where appropriate. As a result, approximately 20 employees primarily in SG&A functions located in North America, Asia and Europe were impacted. Payments related to the remaining severance and benefits accrual are expected to be paid by the end of the fourth quarter of fiscal 2019. Plans Prior to Fiscal 2014 The restructuring accrual for plans that commenced prior to fiscal year 2014 was $2.0 million , which consists of immaterial accruals from various restructuring plans.

Income Tax Disclosure [Abstract]
Income Taxes	Note 12. Income Taxes The Company recorded an income tax benefit of $1.2 million and $0.4 million related to the income (loss) from continuing operations for the three and six months ended months ended January 2, 2016 , respectively. The Company recorded an income tax expense of $ 8.5 million and $ 14.3 million related to the loss from continuing operations for the three and six months ended December 27, 2014 , respectively. The income tax benefit related to the income (loss) from continuing operations recorded for the three and six months ended January 2, 2016 and December 27, 2014 primarily relates to income tax in certain foreign and state jurisdictions based on the Company’s forecasted pre-tax income or loss for the respective year. In addition, for the three and six months ended January 2, 2016 the Company’s income tax provision includes a tax benefit of $8.8 million and $22.2 million , respectively, related to the income tax intraperiod tax allocation rules for discontinued operations and other comprehensive income. The income tax benefit related to the loss from continuing operations for the six months ended January 2, 2016 also includes a tax expense of $8.9 million related to a one-time increase in valuation allowance associated with deferred tax assets transferred to Lumentum in connection with the Separation. The income tax expense (benefit) related to the income (loss) from continuing operations recorded differs from the expected tax expense (benefit) that would be calculated by applying the federal statutory rate to the Company’s income (loss) from continuing operations before taxes primarily due to the increases in valuation allowance for deferred tax assets attributable to the Company’s domestic and foreign losses from continuing operations, the income tax benefit recorded in continuing operations under the income tax intraperiod tax allocation rules, and the increase in valuation allowance associated with deferred tax assets transferred to Lumentum in connection with the separation. At the beginning of the second quarter of fiscal 2016, the Company prospectively adopted the authoritative guidance on balance sheet classification of deferred taxes, which requires deferred tax assets and liabilities, and any related valuation allowance, to be classified as non-current on the balance sheet. The adoption resulted in a reclass of $3.1 million of current net deferred tax assets and $0.7 million of current net deferred tax liabilities to non-current deferred assets and liabilities netted on a jurisdiction by jurisdiction basis. As of January 2, 2016 and June 27, 2015 , the Company’s unrecognized tax benefits totaled $37.0 million and $37.4 million , respectively, and are included in deferred taxes and other non-current tax liabilities, net. The Company had $1.6 million accrued for the payment of interest and penalties at January 2, 2016 . The unrecognized tax benefits that may be recognized during the next twelve months are approximately $0.1 million .

Equity [Abstract]
Stockholders' Equity	Note 13. Stockholders' Equity Repurchase of Common Stock In May 2014, the Company's Board of Directors authorized a stock repurchase program under which the Company may purchase shares of its common stock worth up to an aggregate purchase price of $100.0 million through open market or private transactions. In October 2015, the Board extended the previously authorized repurchase program to utilize the remaining unused dollar amount from the program of approximately $40 million . In November 2015, the Company entered into a $40.0 million accelerated share repurchase agreement (the “ASR”) with a financial institution that was completed during the third quarter of fiscal 2016. Upon making the upfront payment of $40.0 million , the Company received an initial delivery of 5.3 million shares from the financial institution during the second quarter of fiscal 2016, which were retired and recorded as a $32.0 million reduction to stockholder’s equity on the Consolidated Balance Sheet. As of January 2, 2016, the ASR was evaluated as an unsettled forward contract indexed to the Company’s own stock, with $8.0 million classified within stockholders’ equity. The Company reflects the repurchase of common stock under the ASR in the period the shares are delivered for the purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The ASR met all of the applicable criteria for equity classification and therefore was not accounted for as a derivative instrument. During the third quarter of fiscal 2016, the ASR was completed and a final delivery of 1.3 million shares was delivered based on the final settlement price of $6.05 per share. All common shares repurchased under this program have been canceled and retired.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Note 14. Stock-Based Compensation Overview The impact on the Company’s results of operations of recording stock-based compensation by function for the three and six months ended January 2, 2016 and December 27, 2014 was as follows (in millions): Three Months Ended Six Months Ended January 2, 2016 December 27, 2014 January 2, 2016 December 27, 2014 Cost of sales $ 1.4 $ 1.0 $ 2.6 $ 2.0 Research and development 1.9 2.0 4.7 3.9 Selling, general and administrative 5.6 7.5 17.6 15.1 Stock-based compensation $ 8.9 $ 10.5 $ 24.9 $ 21.0 Approximately $0.9 million of stock-based compensation was capitalized to inventory at January 2, 2016 . Full Value Awards Full Value Awards refer to RSUs and Performance Units that are granted with the exercise price equal to zero and are converted to shares immediately upon vesting. These Full Value Awards are performance-based, time-based or a combination of both and expected to vest over one to four years. The fair value of the time-based Full Value Awards is based on the closing market price of the Company’s common stock on the date of award. During the six months ended January 2, 2016 and December 27, 2014 , the Company granted 5.3 million and 5.2 million RSUs, of which 0.5 million and 0.7 million , respectively, are performance-based RSUs with market conditions (“MSUs”). These MSU shares represent the target amount of grants, and the actual number of shares awarded upon vesting of the MSUs may be higher or lower depending upon the achievement of the relevant market conditions. The majority of MSUs vest in equal annual installments over three years based on the attainment of certain total shareholder return performance measures and the employee’s continued service through the vest date. The aggregate grant-date fair value of MSUs granted during the first quarter of fiscal 2016 and fiscal 2015 was estimated to be $2.9 million and $8.5 million , respectively, and was calculated using a Monte Carlo simulation. The remaining 4.8 million and 4.5 million granted during the six months ended January 2, 2016 and December 27, 2014 are mainly time-based RSUs. The majority of these time-based RSUs vest over three years , with 33% vesting after one year and the balance vesting quarterly over the remaining two years . The grant amounts and grant-date fair values during the three and six months ended December 27, 2014 represent the Company’s historical grant information and have not been adjusted to remove grants made to employees who transferred to Lumentum as part of the Separation. As of January 2, 2016 , $52.3 million of unrecognized stock-based compensation cost related to Full Value Awards remains to be amortized. That cost is expected to be recognized over an estimated amortization period of 2.2 years . Full Value Awards are converted into shares upon vesting. Shares equivalent in value to the minimum withholding taxes liability on the vested shares are withheld by the Company for the payment of such taxes. During the six months ended January 2, 2016 and December 27, 2014 , the Company paid $7.8 million and $11.9 million , respectively, and classified the payments as operating cash outflows in the Consolidated Statement of Cash Flows. Impact on Stock-based Compensation Due to Separation In connection with the separation of the Lumentum business on August 1, 2015 and in accordance with the Employee Matters Agreement, the Company made certain adjustments to the exercise price and number of shares underlying stock-based compensation awards with the intention of preserving the economic value of the awards for Viavi employees. These adjustments resulted in a modification of equity awards with total incremental stock-based compensation of $13.6 million , of which $8.3 million was expensed in the first two quarters of fiscal 2016. The remaining $5.3 million will be amortized over the remaining requisite service period from Separation Date to the end of the vesting term. Valuation Assumptions The Company estimates the fair value of the new MSUs granted using a Monte Carlo simulation based on the assumptions described below for the following periods: Six Months Ended January 2, 2016 December 27, 2014 Volatility of common stock 33.0 % 40.8 % Average volatility of peer companies 52.6 % 53.4 % Average correlation coefficient of peer companies 0.0887 0.2156 Risk-free interest rate 0.8 % 0.6 %

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
Employee Benefit Plans	Note 15. Employee Pension and Other Benefit Plans In connection with the separation of Lumentum on August 1, 2015, the Company transferred the liabilities and assets of the Switzerland defined benefit pension plans to Lumentum in the amount of $6.7 million and $4.6 million , respectively. The Company sponsors significant qualified and non-qualified pension plans for certain past and present employees in the United Kingdom (“U.K.”) and Germany. The Company also is responsible for the non-pension post-retirement benefit obligation assumed from a past acquisition. Most of the plans have been closed to new participants and no additional service costs are being accrued, except for certain plans in Germany assumed in connection with acquisitions during fiscal 2010. Benefits are generally based upon years of service and compensation or stated amounts for each year of service. As of January 2, 2016 the U.K. plan was partially funded while the other plans were unfunded. The Company’s policy for funded plans is to make contributions equal to or greater than the requirements prescribed by law or regulation. For unfunded plans, the Company pays the post-retirement benefits when due. During the six months ended January 2, 2016 , the Company contributed $0.7 million to the U.K. plan. The funded plans assets consist primarily of managed investments. The following table presents the components of the net periodic cost for the pension and benefits plans ( in millions ): Three Months Ended Six Months Ended Pension Benefits January 2, 2016 December 27, 2014 January 2, 2016 December 27, 2014 Service cost $ 0.1 $ — $ 0.2 $ 0.1 Interest cost 0.7 1.0 1.5 2.0 Expected return on plan assets (0.4 ) (0.4 ) (0.8 ) (0.8 ) Recognized net actuarial losses 0.1 0.1 0.3 0.2 Net periodic benefit cost $ 0.5 $ 0.7 $ 1.2 $ 1.5 Both the calculation of the projected benefit obligation and net periodic cost are based upon actuarial valuations. These valuations use participant-specific information such as salary, age, years of service, and assumptions about interest rates, pension increases and other factors. At a minimum, the Company evaluates these assumptions annually and makes changes as necessary. The Company expects to incur cash outlays of approximately $5.9 million related to its defined benefit pension plans during fiscal 2016 to make current benefit payments and fund future obligations. As of January 2, 2016 , approximately $2.3 million had been incurred. These payments have been estimated based on the same assumptions used to measure the Company’s projected benefit obligation at June 27, 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 16. Commitments and Contingencies Legal Proceedings The Company is subject to a variety of claims and suits that arise from time to time in the ordinary course of our business. While management currently believes that resolving claims against the Company, individually or in aggregate, will not have a material adverse impact on its financial position, results of operations or statement of cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. Were an unfavorable final outcome to occur, there exists the possibility of a material adverse impact on the Company’s financial position, results of operations or cash flows for the period in which the effect becomes reasonably estimable. Guarantees In accordance with authoritative guidance which requires that upon issuance of a guarantee, the guarantor must recognize a liability for the fair value of the obligation it assumes under that guarantee. In addition, disclosures about the guarantees that an entity has issued, including a tabular reconciliation of the changes of the entity’s product warranty liabilities, are required. The Company from time to time enters into certain types of contracts that contingently require the Company to indemnify parties against third-party claims. These contracts primarily relate to: (i) divestiture agreements, under which the Company may provide customary indemnifications to purchasers of the Company’s businesses or assets; (ii) certain real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company’s use of the applicable premises; and (iii) certain agreements with the Company’s officers, directors and employees, under which the Company may be required to indemnify such persons for liabilities arising out of their employment relationship. The terms of such obligations vary. Generally, a maximum obligation is not explicitly stated. Because the obligated amounts of these types of agreements often are not explicitly stated, the overall maximum amount of the obligations cannot be reasonably estimated. Historically, the Company has not been obligated to make significant payments for these obligations, and no liabilities have been recorded for these obligations on the consolidated balance sheet as of January 2, 2016 and June 27, 2015 . Product Warranties In general, the Company offers a three -year warranty for most of its products. The Company provides reserves for the estimated costs of product warranties at the time revenue is recognized. The Company estimates the costs of its warranty obligations based on its historical experience of known product failure rates, use of materials to repair or replace defective products and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise with specific products. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. The following table presents the changes in the Company’s warranty reserve during fiscal 2016 and fiscal 2015 ( in millions ): Three Months Ended Six Months Ended January 2, 2016 December 27, 2014 January 2, 2016 December 27, 2014 Balance as of beginning of period $ 4.0 $ 3.6 $ 3.7 $ 3.6 Provision for warranty 0.8 1.0 1.7 1.9 Utilization of reserve (0.7 ) (1.2 ) (1.5 ) (2.1 ) Adjustments related to pre-existing warranties (including changes in estimates) 0.2 0.1 0.4 0.1 Balance as of end of period $ 4.3 $ 3.5 $ 4.3 $ 3.5

Segment Reporting [Abstract]
Operating Segments and Geographic Information	Note 17. Operating Segments The Company evaluates its reportable segments in accordance with the authoritative guidance on segment reporting. The Company’s Interim Chief Executive Officer, Richard Belluzzo, is the Company’s Chief Operating Decision Maker (“CODM”) pursuant to the guidance. The CODM allocates resources to the segments based on their business prospects, competitive factors, net revenue and operating results. The Company provides software and hardware platforms and instruments that deliver end-to-end visibility across physical, virtual and hybrid networks. Viavi’s solutions provide intelligence and insight across the network ecosystem to optimize networks and support more profitable, higher-performing networks for our customers. Viavi is also a leader in anti-counterfeiting solutions for currency authentication and high-value optical components and instruments for diverse government and commercial applications. The Company’s reportable segments are: (i) Network Enablement (“NE”): NE provides testing solutions that access the network to perform build out and maintenance tasks. These solutions include instruments and software to design, build, turn-up, certify, troubleshoot, and optimize networks. (ii) Service Enablement (“SE”): SE solutions are embedded systems that yield network, service and application performance data. These solutions—including microprobes and software—monitor, collect and analyze network data to reveal the actual customer experience and to identify opportunities for new revenue streams and network optimization. (iii) Optical Security and Performance Products (“OSP”): OSP provides innovative optical security solutions, with a strategic focus on serving the anti-counterfeiting market through advanced security pigments, thread substrates and printed features for the currency, pharmaceutical and consumer electronic segments. OSP also provides thin-film coating solutions for 3D sensing applications. Changes to Segment Reporting Following the Separation in the first quarter of fiscal 2016, the Company made changes to its segment measures to reflect how the CODM manages the business post-separation as described below. The CODM manages the Company in two broad business categories: Network and Service Enablement ("NSE") and OSP. NSE operates in two segments, NE and SE, whereas OSP operates as a single segment. The CODM evaluates segment performance of the NSE business based on NE and SE segment gross margin and NSE operating margin as a whole. Operating expenses associated with the NSE business are not allocated to the NE and SE segments within NSE, as they are managed centrally at the business unit level. The CODM evaluates segment performance of the OSP business based on OSP segment operating margin. In addition, prior to the first quarter of fiscal 2016 the Company did not allocate certain corporate-level operating expenses associated with its shared-service function to its segment results. Beginning in the first quarter of fiscal 2016, the Company has allocated these corporate-level operating expenses to its segment results, with the exception of certain non-recurring activities and other items as discussed below. The Company does not allocate stock-based compensation, acquisition-related charges and amortization of intangibles, restructuring and related charges, non-operating income and expenses, or other non-recurring charges to our segments because Management does not include this information in its measurement of the performance of the operating segments. These items are presented as “Reconciling Items” in the table below. As a result of the Separation, the Company excluded the results of the Lumentum business which historically consisted of the CCOP segment and the WaveReady product line within the NE segment for all periods presented. Refer to “ Note 3. Discontinued Operations ” for more information on the Separation. Additionally, the Company’s Video Assurance product line was moved out of its NE segment and into its SE segment during the first quarter of fiscal 2016. The segment information for all periods presented has been revised to be comparable with the changes in the Company’s segment reporting measures.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal Years	Fiscal Years The Company utilizes a 52 - 53 week fiscal year ending on the Saturday closest to June 30th. The Company’s fiscal 2016 is a 53 -week year ending on July 2, 2016 . The Company’s fiscal 2015 was a 52 -week year ending on June 27, 2015 .
Principles of Consolidation	Principles of Consolidation The amounts presented in the consolidated financial statements have been prepared in accordance with U.S. GAAP and include the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements, the reported amount of Net revenues and expenses and the disclosure of commitments and contingencies during the reporting periods. The Company bases estimates on historical experience and on various assumptions about the future believed to be reasonable based on available information. The Company’s reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information.
Recently Issued Accounting Pronouncements	In January 2016, the FASB (“Financial Accounting Standards Board”) issued guidance that requires an entity to measure equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, it requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset. It also eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The guidance is effective for the company in the first quarter of fiscal 2019. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In November 2015, the FASB issued guidance requiring deferred tax assets and liabilities, and any related valuation allowance, to be classified as non-current on the balance sheet. This classification eliminates the need to separately identify the net current and net non-current deferred tax asset or liability in each jurisdiction. The Company elected to prospectively adopt the guidance in the beginning of the second quarter of fiscal 2016. Refer to “ Note 12. Income Taxes ” for more information regarding the impact of adopting this guidance. In July 2015, the FASB issued guidance to change the subsequent measurement of inventory from lower of cost or market to lower of cost and net realizable value. The guidance is effective for the Company in the first quarter of fiscal 2018. Earlier application is permitted as of the beginning of an interim or annual reporting period. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In May 2015, the FASB issued guidance to remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using net asset value per share practical expedient. The guidance is effective for the Company in the first quarter of fiscal 2017 and may apply to certain pension assets. The guidance will be applied retrospectively and earlier adoption is permitted. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In April 2015, the FASB issued new authoritative guidance to provide a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. Prospective application is required and early adoption is permitted. This guidance is effective for the Company in the first quarter of fiscal 2017 and may apply to the qualified and the non-qualified pension plans in certain countries. The Company will not early adopt and is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements. In April 2015, the FASB issued new authoritative guidance to simplify the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding liability, consistent with debt discounts or premiums. This guidance is effective for the Company in the first quarter of fiscal 2017 for its convertible debt, and will be applied retrospectively. The consolidated balance sheet of each individual period presented will be adjusted to reflect the period-specific effects of applying this new guidance. In May 2014, the FASB issued new authoritative guidance related to revenue recognition. This guidance will replace current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. The new revenue recognition guidance provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance allows for either full retrospective adoption or modified retrospective adoption. The FASB deferred the effective date for this guidance by one year to December 15, 2017 for annual reporting periods beginning after such date. Earlier application of this guidance is permitted but not before the original date of December 15, 2016. The guidance is effective for the company in the first quarter of fiscal 2019. The Company is evaluating the impact that this new accounting guidance will have on its consolidated financial statements and related disclosures.
