	Organization and Summary of significant accounting policies
	Organization and nature of operations
	MRV Communications, Inc. ("MRV" or the "Company"), a Delaware corporation, is a global supplier of communications solutions to telecommunications service providers, enterprises and governments throughout the world. MRV's products enable customers to provide high-bandwidth data and video services and mobile communications services more efficiently and cost effectively. MRV markets and sells its products worldwide, through a variety of channels, which include a dedicated direct sales force, manufacturers' representatives, value-added-resellers, distributors and systems integrators. MRV conducts its business along two principal segments: the Network Equipment segment and the Network Integration segment. MRV's Network Equipment segment designs, manufactures, sells, and services equipment used by commercial customers, governments, and telecommunications service providers. Products include switches, optical transport platforms, physical layer products and out-of-band management products, and specialized networking products. The Italian Network Integration segment provides network system design, integration and distribution services that include products manufactured by third-party vendors.
	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 March 31, 2014 (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, 2013 (the “2013 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 March 31, 2014, and the results of its operations and comprehensive income (loss) for the three months ended March 31, 2014 and 2013 and its cash flows for the three months ended March 31, 2014 and 2013. 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.

	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.
	As of March 31, 2014 and December 31, 2013 , the Company had cash equivalents consisting of money market funds of $14.0 million and $14.0 million, respectively that were classified as Level 1 investments and were quoted at market price. Cash equivalents are included in the consolidated balance sheets as follows (in thousands):
		Cost		Fair Value
	31-Dec-13	$	14,001	$	14,001
	31-Mar-14	$	14,003	$	14,003
	During 2014 the Company updated the estimated fair value as of the issuance date of 250,000 warrants that were issued to plaintiffs' counsel on February 18, 2014 in a litigation matter originally recorded as a liability in 2013. In calculating the fair value, the Company used the Black Scholes option pricing model with level 2 inputs including a volatility of 41% based on the Company's historical quoted prices and peer company data, the risk free interest rate of 1.5% 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 $6.59 per warrant. In relation to this revaluation, the Company recorded expense of $0.4 million for the three months ended March 31, 2014. Upon issuance and revaluation, the warrants were removed from liabilities and recorded as a component of additional paid in capital. As the criteria was met under ASU 480 and ASU 815.

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. Accounts receivable are charged off at the point they are considered uncollectible.
	The following table summarizes the changes in the allowance for doubtful accounts during the three months ended March 31, 2014 (in thousands):
		Three months ended
		March 31, 2014
	Balance at beginning of period		$2,183

	The balance of the intangible asset was $0.8 million as of March 31, 2014 and $0.9 million as of December 31, 2013. This asset, which represents software license agreements, was not placed in service as of March 31, 2014, therefore amortization of intangible assets was zero for the three months ended March 31, 2014 and March 31, 2013. The terms of the license agreements are indefinite and once placed in service, the Company plans to amortize the cost over the estimated useful life, which is approximately 5 years.

Earnings Per Share [Abstract]	'
Net Income (Loss) Per Share	'
	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 0.3 million shares were excluded from the computation of dilutive shares for the three months ended March 31, 2014 because of the net loss. Outstanding stock options to purchase 0.4 million shares were excluded in the computation of dilutive shares for the three months ended March 31, 2013 because of the net loss. In addition, for the three months ended March 31, 2014, there were 9.3 thousand potentially dilutive shares excluded from the calculation of diluted net loss per share because they were anti-dilutive, and there were no potentially dilutive shares to be excluded from the calculation of diluted net loss per share for the three months ended March 31, 2013. Treasury shares are excluded from the number of shares outstanding.

	Total share-based compensation expense (1)		$147		$219
	-1	Income tax benefits realized from stock option exercises and similar awards were immaterial in both periods.
	The Company granted no stock options and no restricted shares during the three months ended March 31, 2014 and the three months ended March 31, 2013. As of March 31, 2014, the total unrecorded deferred share-based compensation balance for unvested securities, net of expected forfeitures, was $0.5 million, which is expected to be amortized over a weighted-average period of 1.1 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. MRV bases volatility on the Company's historical quoted prices and peer company data. There were no options modified during the three months ended March 31, 2014 and 2013, respectively.

Indemnification Obligations	'
	Indemnification Obligations
	Our agreements for the sale of our Source Photonics, CES, Interdata and Alcadon businesses include customary indemnification obligations running to the respective buyers.
	We have agreements whereby our officers and directors are indemnified for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we retain directors and officers insurance that reduces our exposure and enables us to recover portions of amounts paid. As a result of our insurance coverage, we believe the estimated fair value of these indemnification agreements is minimal. Accordingly, no liabilities have been recorded for these agreements as of March 31, 2014 and December 31, 2013.

The outcome of any such matters is currently not determinable. In addition, we were party to the litigation set forth below.
	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 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 $10.0 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 included, among other things, (a) a release of all claims relating to the derivative litigation 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) payment of attorneys' fees to plaintiffs' counsel including $500,000 in cash and 250,000 warrants to purchase the Company's Common Stock, with a five-year term and strike price of the closing price of the Company's Common Stock on the date an order of the federal District Court approving the settlement becomes final; (d) the 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 Stipulation 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 was also required to undertake certain corporate governance reform actions,all of which are either in process of implementation or have 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 December 31, 2013 above the insured amount.
	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 our business, operating results and financial condition.

Accounts Receivable Factoring	'
	Accounts Receivable Factoring
	The Company's Italian subsidiary 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. At March 31, 2014, Tecnonet's factoring facility agreements permitted the factoring of up to €10.0 million, or $13.8 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. The Company has no retained interests or servicing liabilities related to the accounts receivable that have been sold in Italy.
	At March 31, 2014, and December 31, 2013, the face amount of total outstanding accounts receivable pursuant to these agreements was $13.8 million and $17.2 million, respectively. Receivables transferred to the factor are derecognized at the date of sale and the proceeds are recorded at fair value. Proceeds consist of a receivable due from the factor. Cash received from the factor is recorded as a reduction of the receivable due from the factor. The related outstanding balances due from the factor were $6.0 million and $7.7 million as of March 31, 2014 and December 31, 2013, respectively, and are included in other receivables on the accompanying balance sheets The related losses on sale were $0.04 million and $0.1 million for the three months ended March 31, 2014 and March 31, 2013, and is included in interest expense on the accompanying consolidated statements of operations.

Since August 15, 2013 the Company has purchased 127,510 shares at a total cost of approximately $1.3 million during the year ended December 31, 2013, leaving $5.7 million for future purchase.

	Provision for income taxes	251			306
	Effective tax rate	(6		)%	(7		)%
	The effective tax rate for the three months ended March 31, 2014 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, 2013, we had net operating losses ("NOLs") of $172.3 million, $93.1 million, and $95.8 million for federal, state, and foreign income tax purposes, respectively. Additionally, the Company had capital loss carryforwards of $110.5 million and $24.0 million for federal and state tax purposes, respectively. The capital loss carry forwards, which were generated by the sale of Source Photonics, expire in 2015. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carry forwards 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 carry forwards existing at that time could be limited. As of March 31, 2014, the US federal and state NOLs had a full valuation allowance.

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 March 31, 2014 (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, 2013 (the “2013 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. Accounts receivable are charged off at the point they are considered uncollectible.
