Exhibit 99.1

MRV Communications, Inc. Agrees to Sell Creative Electronic Systems SA Business Unit to Consortium of Private Equity Firms

CHATSWORTH, Calif., December 7, 2011 — MRV Communications, Inc. (OTCQB: MRVC) (“MRV” or the “Company”), a leading provider of optical communications network infrastructure equipment and integration and managed services, today announced that it executed a definitive agreement with a consortium of European private equity firms led by Vinci Capital SA for their acquisition of Creative Electronic Systems SA (CES), a wholly owned subsidiary of MRV. Based in Geneva, Switzerland, CES is a designer and manufacturer of complex high-performance avionics, defense and communications boards, sub-systems and complete systems. Headwaters MB was the exclusive financial advisor to MRV for the transaction.

The transaction is valued at approximately $24.6 million (net of approximately $3.2 million of operating cash to be retained by CES), payable on closing, less certain deductions and escrows set forth in the purchase agreement. It is conditioned upon receiving MRV stockholder approval, completion of senior debt financing and certain due diligence items by the purchasers, and other customary closing conditions. Deductions of retention and other employee cash bonuses are approximately $0.6 million, and two escrows have been created to withhold approximately $4.1 million of the proceeds in connection with certain restricted cash amounts and for indemnification purposes. The closing is expected to occur by the end of January 2012.

Commenting on the transaction, MRV’s CFO and Interim CEO, Chris King stated, “This sale is reflective of our commitment to conduct divestitures when we can sell a business unit at a premium to the value we can realize through its ongoing operations. Further, if completed, the proceeds from this sale increase the cash available for return to our stockholders.”

MRV remains a leading provider of network infrastructure equipment and network management products, as well as network integration and managed services. These products and services include optical transport and WDM solutions, optical carrier Ethernet access, and infrastructure management and services for high-speed carrier and enterprise networks.

King concluded, “We believe that we achieved an attractive sale price for CES, and that CES will continue to grow under the stewardship of its new owners. On behalf of MRV, I would like to thank all of the employees who contributed to the growth of CES and I wish them future success.”
