Commitments and Contingencies Disclosure [Abstract]
Indemnification Obligations	Indemnification Obligations In connection with the sale by MRV of Source Photonics, Inc. ("SPI") in October 2010, MRV agreed to indemnify the buyer against certain claims brought after the closing for prior-occurring events. Most of the indemnification obligations have expired; however, indemnification related to employee benefits, environmental liabilities and taxes extend until their applicable statute of limitations has run 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. The Company has received a notice from SPI, advising the Company of a tax audit for periods including tax returns filed prior to the acquisition of SPI by the buyer. In April 2017 this matter was resolved. MRV does not anticipate any further material impacts upon its business, operating results or financial condition related to this matter. (See Note 17, Subsequent Events) Our agreements for the sale of certain business (CES in March 2012, Alcadon and Interdata in October 2012, and Tecnonet in December 2015) include customary indemnification obligations to the respective buyers. In connection with the sale of CES, MRV agreed to indemnify the buyer for the representations and warranties made in the sale purchase agreement and purchased an insurance policy to protect against any claims of indemnification related to the representations and warranties. In addition, the Company has indemnification obligations to its current and former officers and directors as set forth in the Company's bylaws. 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. No liabilities have been recorded for these indemnification agreements as of March 31, 2017 and December 31, 2016. In the normal course of business to facilitate sales of its products, MRV indemnifies other parties, including customers, lessors and parties to other transactions with us, with respect to certain matters. The Company has agreed to hold the other parties harmless against losses arising from a breach of representation or covenants, for intellectual property infringement, or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. We cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these obligations. Over the last decade, the Company has not incurred any significant expense as a result of obligations of this type. Accordingly, the Company has not accrued any amounts for such indemnification obligations. However, there can be no assurances that expenses will not be incurred under these indemnification provisions in the future.
