EMCORE Announces Successful Telcordia® Qualification of Tunable XFP Transceiver

ALBUQUERQUE, NM — June 29th, 2011 - EMCORE Corporation (NASDAQ:EMKR), a leading provider of compound semiconductor-based components, subsystems and systems for the fiber optics and solar power markets, today announced the successful Telcordia® qualification and production release of its Tunable XFP (TXFP) transceiver.

“Our successful Telcordia ® GR-468 qualification and production release of the TXFP represents a major milestone for EMCORE. We have demonstrated that our technology exceeds the mandated industry robustness and reliability standards,” stated Rob Stone, Director of EMCORE’s Telecom Business Unit. “We have been successful in our goal of enabling customers to replace their legacy 10Gb/s long-haul tunable interfaces with a more power and size efficient module, which improves both their operational and capital expenses.”

The Tunable XFP incorporates the latest “ClearLight” generation of the EMCORE patented External Cavity Laser (ECL) technology, which has been deployed in worldwide fiber networks by multiple carriers since 2004. All active optical subcomponents are manufactured in-house, leveraging the EMCORE core capability in wafer growth and fabrication. In addition to our current volume manufacturing location, EMCORE will be adding additional capacity at our contract manufacturer over the second half of 2011.
