	Organization and Summary of significant accounting policies
	Organization and nature of operations
	MRV Communications, Inc. (“MRV”, "we", "our", the “Company”, and "us") and its wholly-owned subsidiaries supply communications equipment and services to carriers, governments and enterprise customers worldwide. We conduct our business along two principal segments: (a) Network Equipment; and (b) Network Integration. Our Network Equipment segment provides communications equipment that facilitates access, transport, aggregation and management of voice, data and video traffic in networks, data centers and laboratories used by telecommunications service providers, cable operators, enterprise customers and governments worldwide. Our Network Integration segment operates primarily in Italy, servicing Tier One carriers, regional carriers, large enterprises, and government institutions. Network Integration provides network system design, integration and distribution services that include products manufactured by third-party vendors. We market and sell our products worldwide, through a variety of channels, which include a dedicated direct sales force, manufacturers' representatives, value-added-resellers, distributors and systems integrators.
	Basis of Presentation
	The consolidated financial statements include the accounts of MRV and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. MRV consolidates the financial results of less than majority-owned subsidiaries when it has effective control, voting control, or has provided the entity's working capital. When investment by others in these enterprises reduces the Company's voting control below 50%, MRV discontinues consolidation and uses the cost or equity method of accounting for these investments, unless otherwise required.
	The consolidated financial statements included herein have been prepared by MRV, and are unaudited, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations although MRV believes that the disclosures are adequate to make the information presented not misleading. The information included in this Quarterly Report on Form 10-Q for the quarter ended September 30, 2013 (this “Form 10-Q”) should be read in conjunction with “Selected Financial Data,” “Management's Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Form 10-K”) filed with the SEC.
	Restricted time deposits represent investments that are restricted as to withdrawal. Restricted time deposits generally secure standby letters of credit, bank lines of credit, or bank loans. Investments in and releases of restricted time deposits are included in investing activities on the Company's Statement of Cash Flows unless the time deposits relate to an underlying bank loan and will be used to repay the loan, in which case the related cash flows are treated as financing activities.
	In the opinion of MRV's management, these unaudited statements contain all adjustments, which include normal recurring adjustments, necessary to present fairly the financial position of MRV as of September 30, 2013, and the results of its operations and comprehensive income (loss) for the three and nine months ended September 30, 2013 and 2012 and its cash flows for the nine months ended September 30, 2013 and 2012. The results reported in these financial statements should not be regarded as necessarily indicative of results that may be expected for the full year or any future periods.
	On March 29, 2012, we sold all of the issued and outstanding capital stock of CES Electronic Systems SA (“CES”). On October 12, 2012, the Company completed the sale of all of the shares of its subsidiary Alcadon - MRV AB ("Alcadon"). On October 16, 2012, the Company completed the sale of its subsidiary Pedrena Enterprises B.V., a Dutch company ("Pedrena"). Pedrena is the parent company of Interdata, which is in turn, the parent company of J3TEL. The Company has reclassified the historical results of CES, Alcadon and Pedrena as discontinued operations in this Form 10-Q for all periods presented. Accordingly, upon completion of the terms of the related sales agreements, the related assets and liabilities of these three entities have been removed from the Company's balance sheets. Cash flows from discontinued operations of these three entities are presented combined with the cash flows from continuing operations in the accompanying Statement of Cash Flows for the nine months ended September 30, 2012. See Note 13 "Discontinued Operations" to the Financial Statements in Item 1 of this Form 10-Q for further discussion.

	Cash and Cash Equivalents and Restricted Time Deposits
	MRV treats highly liquid investments with an original maturity of 90 days or less as cash equivalents. Investments with maturities of less than one year are considered short-term, and are included on the balance sheet in restricted time deposits. MRV maintains cash balances and investments in qualified financial institutions, and at various times such amounts are in excess of federal insured limits.

Fair Value Measurement	'
	Fair Value Measurement
	MRV's financial instruments, including cash and cash equivalents, restricted time deposits, accounts receivable, other receivables, other assets, accounts payable, accrued liabilities and short-term debt obligations, are carried at cost, which approximates their fair market value.
	ASC 820-10 Fair Value Measurements defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820-10 establishes a three-level hierarchy that prioritizes the use of observable inputs. The fair value hierarchy is divided into three levels based on the source of inputs as follows: Level 1 -Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access; Level 2 - Valuations for which all significant inputs are observable, either directly or indirectly, other than level 1 inputs; Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
	All of MRV's assets and a majority of its liabilities that are measured at fair value are measured using the unadjusted quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. Under this standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date.
	During 2013 the Company updated the estimated fair value as of September 30, 2013 of 250,000 warrants that will be issued to plaintiffs' counsel in a litigation matter originally recorded as a liability in 2012. In calculating the fair value, the Company used the Black Scholes option pricing model with level 2 inputs including a volatility of 45% based on the Company's historical quoted prices and peer company data, the risk free interest rate of 1.4% and the 5 years expected term of the warrants. Volatility based on both the Company's historical quoted prices and peer company data was used as the Company's stock is thinly traded. The resulting fair value was $4.27 per warrant. In relation to this revaluation, the Company recorded expense of $0.2 million for the three months ended September 30, 2013 and income of $0.01 million for the nine months ended September 30, 2013.

Receivables [Abstract]	'
Credit Risk	'
	Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents placed with high credit quality institutions and accounts receivable due from customers. MRV evaluates the collectability of accounts receivable based on a combination of factors. If the Company becomes aware of a customer's inability to meet its financial obligations after a sale has occurred, the Company records an allowance to reduce the net receivable to the amount that it reasonably believes to be collectable from the customer. For all other customers, the Company records allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment, and historical experience. If the financial conditions of MRV's customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future.
	The following table summarizes the changes in the allowance for doubtful accounts during the nine months ended September 30, 2013 (in thousands):
		Nine months ended

This asset, which represents a software license agreement, was not placed in service as of September 30, 2013, therefore amortization of intangible assets was zero for the nine months ended September 30, 2013 and September 30, 2012. The term of the license agreement is indefinite and once placed in service, the Company plans to amortize the cost over the estimated useful life, which is approximately 5 years.

	Net Income (Loss) Per Share
	Basic net income (loss) per share is computed using the weighted average number of shares of common stock ("Common Stock") outstanding, including restricted shares which, although they are legally outstanding and have voting rights, are subject to vesting and are treated as common stock equivalents in calculating basic income (loss) per share. Diluted net income per share is computed using the weighted average number of shares of Common Stock outstanding and dilutive potential shares of Common Stock from stock options outstanding during the period. Diluted shares outstanding also include the dilutive effect of in-the-money options, which is calculated based on the average share price for each period using the treasury stock method.
	Outstanding stock options to purchase 0.4 million shares were excluded from the computation of dilutive shares for the three months ended September 30, 2013 because of the net loss. Outstanding stock options to purchase 0.5 million shares were excluded in the computation of dilutive shares for the three months ended September 30, 2012 because they were anti-dilutive. Treasury shares are excluded from the number of shares outstanding.
	Outstanding stock options to purchase 0.4 million shares were excluded from the computation of dilutive shares for the nine months ended September 30, 2013 because of the net loss. Outstanding stock options to purchase 5,903 shares were excluded from the computation of dilutive shares for the nine months ended September 30, 2012 because of the net loss. In addition, for the nine months ended September 30, 2012 there were 0.5 million potentially dilutive shares excluded from the calculation of diluted net loss per share because they were anti-dilutive. Treasury shares are excluded from the number of shares outstanding.

	-1	Income tax benefits realized from stock option exercises and similar awards were immaterial in both periods.
	The Company granted 80,242 stock options during the nine months ended September 30, 2013 and the related weighted average fair value was $4.89 per share. The average fair value of 91,388 restricted shares granted during the nine months ended September 30, 2013 was $9.98 per share. The Company granted 17,736 stock options during the nine months ended September 30, 2012 and the related weighted average fair value was $9.60 per share. The average fair value of 39,325 restricted shares granted during the nine months ended September 30, 2012 was $16.20 per share. As of September 30, 2013, the total unrecorded deferred share-based compensation balance for unvested securities, net of expected forfeitures, was $0.9 million, which is expected to be amortized over a weighted-average period of 1.7 years.
	Valuation Assumptions
	MRV uses the Black-Scholes option pricing model to estimate the fair value of stock option awards or related modifications. The Black-Scholes model requires the use of subjective and complex assumptions including the option's expected life and the underlying stock price volatility. In 2012 MRV assumed volatility to approximate historical volatility. In 2013, MRV based volatility on the Company's historical quoted prices and peer company data. The following weighted average assumptions were used for estimating the fair value of options modified during the nine months ended September 30, 2013 and 2012, respectively:
	Nine months ended September 30,	2013		2012
	Risk-free interest rate	1.2	%	0.8	%
	Dividend yield (1)	—		—
	Volatility	51.9	%	89	%
	Expected life (in years)	5.7		5.5
	(1) As the Company does not pay a dividend on a regular basis, and dividends paid in the past have been special in nature, a dividend rate of zero was used.

Network Equipment designs, manufactures, distributes and services optical networking solutions and Internet infrastructure products, and Network Integration distributes network solutions and Internet infrastructure products and provides value-added integration and support services for customers' networks.
	The accounting policies of the segments are the same as those described in the summary of significant accounting polices disclosed in MRV's 2012 Form 10-K. MRV evaluates segment performance based on revenues, gross profit and operating income (loss) of each segment. As such, there are no separately identifiable Statements of Operations data below operating income (loss).
	The following table summarizes revenues by segment, including intersegment revenues (in thousands):
		Three Months Ended						Nine Months Ended

	Total		$38,385			$34,666			$115,465			$105,707
	Network Equipment revenue primarily consists of optical communication systems that include Metro Ethernet equipment, optical transport equipment, lab automation equipment, out-of-band network equipment, and the related service revenue and fiber optic components sold as part of system solutions. Network Integration revenue primarily consists of value-added integration and support service revenue, related third-party product sales (including third-party product sales through distribution) and fiber optic components sold as part of system solutions. All Network Integration's sales are within Italy.
	One customer accounted for $32.5 million and $25.6 million of revenue in Network Integration revenue, or 28% and 24% of total revenue, for the nine months ended September 30, 2013 and 2012, respectively. Another customer accounted for $12.9 million and $11.7 million of revenue in Network Integration revenue, or 11% of total revenue, for both the nine months ended September 30, 2013 and 2012, respectively.
	The same customer in Network Integration accounted for 12% and 21% of net accounts receivable as of September 30, 2013, and December 31, 2012, respectively.

	Indemnification Obligations
	In connection with the sale by MRV of Source Photonics, Inc. and related entities in October 2010, MRV agreed to indemnify the buyer against certain claims brought after the closing for prior-occurring events.  Certain of the indemnification obligations have expired. However, indemnification obligations related to intellectual property extend until the third anniversary of the closing, indemnification obligations related to employee benefits, environmental liabilities and taxes extend until their applicable statute of limitations has expired plus 90 days, and indemnification obligations are not time limited for title and ownership representations.  These indemnification obligations are subject to a $1.0 million deductible and a $20.0 million cap and we have purchased an insurance policy to protect against such obligations. In connection with the sale by MRV of CES in March 2012, MRV agreed to indemnify the buyer for the representations and warranties made in the sale purchase agreement, and we have purchased an insurance policy to protect us against any claims of indemnification related to the representations and warranties. Our sale purchase agreements for the sale of Pedrena and Alcadon include customary indemnification obligations. In addition, in connection with the sale of Pedrena the Company and the buyer entered into a Representations and Warranties Agreement that contains an arrangement whereby if the Company does not obtain a representations and warranties insurance policy within 90 days of close of the sale transaction, and if the Company's cash falls below $20 million prior to December 31, 2013, the Company will deposit 1.5 million euros (or $2.0 million U.S. equivalent as of December 31, 2012) in an escrow account to secure its indemnification obligations under the Representations and Warranties Agreement. The Company has elected not to obtain the insurance policy and expects to maintain cash balances sufficient to avoid making a deposit.

Litigation	'
	Litigation
	We are subject to legal claims and litigation in the ordinary course of business, including but not limited to product liability, employment and intellectual property claims. The outcome of any such matters is currently not determinable. In addition, we are party to the litigation set forth below, and if one or more of the matters listed below or otherwise is ultimately determined not in our favor, it could have a material adverse effect on our consolidated financial position or results of operations in the period in which they occur.
	In connection with the Company's past stock option grant practices, MRV and certain of its former directors and officers have been subjected to a number of stockholder lawsuits. In June 2008, the Company announced that our Board of Directors, based on information provided by management, and in consultation with management, concluded that the financial statements and the related reports of our independent public accountants should not be relied upon due to the Company's intention to restate its financial results from 2002 through 2008 to correct its accounting for option grants and other issues and a restatement of the Company's financial statements was filed in its Annual Report on Form 10-K for the year ended December 31, 2008 in October 2009.
	From June to August 2008, five purported stockholder derivative and securities class action lawsuits were filed in the U.S. District Court in the Central District of California and one derivative lawsuit was filed in the Superior Court of the State of California against the Company and certain of our former officers and directors. The five lawsuits filed in the Central District of California were consolidated. Claims were asserted under Section 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5 promulgated thereunder. In November 2010, the judge overseeing the securities class action lawsuits gave final approval to a stipulated $10 million settlement agreement, which was covered by our director and officer insurance policies. The federal and state derivative lawsuits were not settled and continued to be litigated.
	As of January 4, 2013, all pending litigation in the federal and state derivative actions was stayed by agreement of the parties pending final Federal Court approval of a settlement between derivative plaintiffs, individual defendants and the Company. On April 8, 2013 the Federal Court preliminarily approved a Stipulation of Settlement (the "Settlement Stipulation"), which includes, among other things, (a) a release of all claims relating to the derivative lawsuits for the Company, the individual defendants and the plaintiffs; (b) a provision that $2.5 million in cash be paid to the Company by the Company's insurance carriers; (c) a payment of attorney's fees to plaintiffs' counsel of up to $500,000 in cash and 250,000 five-year term warrants to purchase the Company's Common Stock at a strike price equal to the closing price of the Company's Common Stock on the day the Court's judgment approving the settlement becomes final (as defined in the Settlement Stipulation); and (d) continued payment by the Company of applicable reasonable attorneys' fees for the individual defendants. On June 6, 2013, the Federal Court granted final approval of the Settlement and on June 13, 2013 entered Judgment dismissing the federal derivative action with prejudice. On June 24, 2013, the State Court entered a dismissal with prejudice of the state derivative action. The Company is now required to undertake certain corporate governance reform actions within 120 days, many of which have already been implemented.
	A majority of the costs related to the Company's and defendants' defense of these actions was paid by the Company's insurance carriers under its director and officer insurance policies, including the securities class action settlement. Insurance proceeds paid to the Company upon settlement of the derivative litigation were $1.0 million. However, MRV has paid and accrued $1.9 million in payment for services of defense counsel and other parties through September 30, 2013 above the insured amount. We have agreed to pay reasonable attorney fees and expenses for the individual defendants in the Stipulation, and will continue to incur our own legal expenses until this matter is finally resolved and non-appealable. Any such future obligations are not determinable at this time.
	From time to time, MRV has received notices from third parties alleging possible infringement of patents with respect to product features or manufacturing processes. Management believes such notices are common in the communications industry because of the large number of patents that have been filed on these subjects. The Company's policy is to discuss these notices with the parties in an effort to demonstrate that MRV's products and/or processes do not violate any patents. The Company has been involved in such discussions with Alcatel-Lucent SA, Apcon, Inc., Finisar Corporation, International Business Machines, Mediacom Broadband LLC, Ortel Communications, Ltd., Nortel Networks Corporation, Rockwell Automation, Inc. and The Lemelson Foundation in the past.
	MRV and its subsidiaries have been named as a defendant in other lawsuits involving matters that the Company considers routine to the nature of its business. Management is of the opinion that the ultimate resolution of such matters will not have a material adverse effect on the business, operating results and financial condition of the Company.

	Accounts Receivable Factoring
	The Company has agreements with unrelated third parties for the factoring of specific accounts receivable in Italy in order to reduce the amount of working capital required to fund such receivables. As of September 30, 2013, the Company's credit facility agreements permit the factoring of up to €15.0 million, or $20.3 million, worth of receivables in operations outside of the United States. The factoring of accounts receivable under these agreements is accounted for as a sale in accordance with ASC 860 Transfers and Servicing. Proceeds on the transfer reflect the face value of the account less a discount. The discount is recorded as a charge in "interest" in the consolidated statement of income in the period of the sale. Net funds received reduced accounts receivable outstanding while increasing cash. The Company has no significant retained interests or servicing liabilities related to the accounts receivable that have been sold in Italy.
	At September 30, 2013, and December 31, 2012, the face amount of total outstanding accounts receivable pursuant to these agreements was $21.2 million and $29.5 million, respectively. The related outstanding balances due from the factor were $15.0 million and $13.3 million as of September 30, 2013 and December 31, 2012, respectively, and are included on the balance sheet as part of other receivables. The related losses on sale were $0.1 million and $0.04 million for the three months ended September 30, 2013 and September 30, 2012, and $0.2 million and $0.1 million for the nine months ended September 30, 2013 and September 30, 2012.

	On May 1, 2012, the Company's Board of Directors (the "Board") declared a dividend and payment to option holders totaling approximately $47.3 million, or $0.30 per share of the Company's Issued Common Stock. The dividend was paid on May 25, 2012 to holders of record as of the close of business on May 16, 2012. The Board also approved a staggered cash payment to option holders equal to the loss in the Black-Scholes fair value of their options as a result of the dividend. Restricted stockholders received per share payments in the same amount as the Company's stock holders promptly following payment of the dividend. Option holders who provided service to the Company at the time of the payment of the dividend received 50 percent of the payment amount in respect of their vested options promptly following payment of the dividend, and received 50 percent of the payment amount 12 months following, conditioned upon continuous service to MRV, subject to certain acceleration conditions such as involuntary termination without cause, death or disability, change of control, or a sale of the business unit in which the option holder is employed. Option holders with unvested options received the cash payment 12 months following as well, subject to the same conditions described above.

	Effective tax rate	(9		)%	40		%	(8		)%	41		%
	The effective tax rate for the three and nine months ended September 30, 2013 fluctuates based on the amount of pre-tax income or loss generated in the various jurisdictions where we conduct operations and pay income tax. In addition, various jurisdictions that generate losses do not benefit from the losses generated due to a valuation allowance placed on those benefits
	As of December 31, 2012, we had net operating losses ("NOLs") of $173.7 million, $112.0 million, and $90.8 million for federal, state, and foreign income tax purposes, respectively. Additionally, the Company had capital loss carryforwards of $110.3 million and $47.1 million for federal and state tax purposes, respectively. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. We may experience an ownership change in the future as a result of subsequent shifts in our stock ownership. If we were to trigger an ownership change in the future, our ability to use any NOLs and capital loss carryforwards existing at that time could be limited. As of September 30, 2013, the U.S. federal and state NOLs continued to carry a full valuation allowance.

	In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). ASU 2013-11 is effective for the first interim or annual period beginning on or after December 15, 2013 with early adoption permitted. ASU 2013-11 amends ASC Topic 740, Income Taxes, to provide guidance and reduce diversity in practice on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. We do not believe that the application of this standard will impact our company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Basis of Presentation	'
	The consolidated financial statements include the accounts of MRV and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. MRV consolidates the financial results of less than majority-owned subsidiaries when it has effective control, voting control, or has provided the entity's working capital. When investment by others in these enterprises reduces the Company's voting control below 50%, MRV discontinues consolidation and uses the cost or equity method of accounting for these investments, unless otherwise required.
	The consolidated financial statements included herein have been prepared by MRV, and are unaudited, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations although MRV believes that the disclosures are adequate to make the information presented not misleading. The information included in this Quarterly Report on Form 10-Q for the quarter ended September 30, 2013 (this “Form 10-Q”) should be read in conjunction with “Selected Financial Data,” “Management's Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Form 10-K”) filed with the SEC.
Restricted Time Deposits	'
	Restricted time deposits represent investments that are restricted as to withdrawal. Restricted time deposits generally secure standby letters of credit, bank lines of credit, or bank loans. Investments in and releases of restricted time deposits are included in investing activities on the Company's Statement of Cash Flows unless the time deposits relate to an underlying bank loan and will be used to repay the loan, in which case the related cash flows are treated as financing activities.
Allowance for Doubtful Accounts Policy	'
	Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents placed with high credit quality institutions and accounts receivable due from customers. MRV evaluates the collectability of accounts receivable based on a combination of factors. If the Company becomes aware of a customer's inability to meet its financial obligations after a sale has occurred, the Company records an allowance to reduce the net receivable to the amount that it reasonably believes to be collectable from the customer. For all other customers, the Company records allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment, and historical experience. If the financial conditions of MRV's customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future.
