MRV Communications, Inc. (“MRV” or the “Company”) (OTC Pink Sheets: MRVC), a leading provider of optical communications systems and services to service providers and enterprises around the world, today announced that it will demonstrate Carrier Ethernet Global Interconnect interoperability for its Optical Carrier Ethernet Access product series at the Ethernet Expo Americas Conference & Exhibition, in New York, November 2-3, 2010. Ethernet Expo 2010 will assemble dozens of experts from the service provider, supplier, and analyst communities to explore the latest market trends in Carrier Ethernet network technologies and services. MRV will be exhibiting in booth #217 at the conference.

The OptiSwitch® Carrier Ethernet Access series is part of the interoperability showcase conducted by the European Advanced Networking Test Center (EANTC) at the show. The demonstration will conclude the 3 rd phase of the EANTC’s test program and focus on expanding interconnect footprint from Europe into North America, adding tests of Ethernet Services OAM and end-to-end performance monitoring of a wholesale Global Carrier Ethernet Network-to-Network service. Results from the tests will be detailed in a white paper available via EANTC's website at

"MRV’s participation at Ethernet Expo Americas further highlights our commitment and proactive pursuit of interoperable solutions for delivering Carrier Ethernet networks that spans over multiple service providers worldwide," said Barry R. Gorsun, President of the Optical Communications Systems division at MRV. “MRV’s exceptional and innovative OptiSwitch solution provides a comprehensive set of hardware-based OAM and Performance Monitoring tools that enable service providers to roll out end-to-end Ethernet Services with SLA assurance and verification across Global Ethernet Interconnection facilities.”

MRV’s OptiSwitch 900 Carrier Ethernet Access series will participate as NIDs (Network Interface Devices) that are deployed at customer locations terminating end-to-end Ethernet MEF specified Ethernet Network-to-Network Service. The solution will enable end-to-end service visibility for global Ethernet interconnects spanning multiple operators’ networks across Europe, and expanding over transatlantic link to USA.

“Global Ethernet Interconnect service is one of the most important topics of today in the booming Carrier Ethernet market--the success of this interoperability testing will give service providers another measure of confidence needed to expand their Ethernet investments,” stated Michael Howard, principal analyst, carrier and data center networks for Infonetics Research. “MRV’s participation in this demonstration shows the company’s dedication to Carrier Ethernet and positions the company as a key player in this growing market.”

"We are delighted that MRV has taken a leading role in providing the NID functionality to the Service Provider Interoperability Test – Phase 3,” said Carsten Rossenhoevel, Managing Director of EANTC. “MRV’s OptiSwitch® 900 carrier-grade Carrier Ethernet demarcation device enabled us to validate Ethernet Fault Management and Performance Monitoring. Using OptiSwitch units in seven service provider POP locations allowed us to monitor the availability of Ethernet services spanning over exchange points in Europe and North America.”

Also at the event, Zeev Draer, Vice President of Strategic Marketing for the Optical Communications Systems division of MRV, will participate in a panel debate entitled “Carrier Ethernet Solutions for Cellular & WiMAX Backhaul” that explores the business and technology barriers that need to be overcome to accelerate Ethernet backhaul deployments along with business cases for different deployment models.
