EMCORE Corporation Announces New Tunable TOSA 10 Gb/s Optical Component Platform

ALBUQUERQUE, NM, Mar 24 (MARKET WIRE) --
EMCORE Corporation (NASDAQ: EMKR), a leading provider of compound
semiconductor-based components and subsystems for the fiber optic and
solar power markets, today announced its plans to release a new full-band
tunable TOSA (transmit optical sub-assembly) product line.

The Tunable TOSA product line combines EMCORE's field proven tunable
External Cavity Laser technology with a co-packaged Mach-Zehnder
modulator, empowering the next generation of ultra-high-density 10 Gb/s
tunable interfaces. The Tunable TOSA provides excellent optical
performance while tuning across more than 90 channels on the 50GHz ITU
grid. With its low power consumption, the EMCORE Tunable TOSA is
compatible with existing XFP module and line-card requirements. The
Tunable TOSA also boasts optical performance similar to existing
solutions using discrete tunable laser and external lithium-niobate
modulator. EMCORE believes this will allow for the migration of existing
300-pin MSA modules to new smaller and pluggable form-factors.

Stephen Krasulick, Vice President and General Manager of EMCORE's Fiber
Optics Division, stated, "Increased density and flexibility are key
requirements all the way up the value-chain, translating to reductions in
both capital and operation expenditures at the carrier level. The EMCORE
Tunable TOSA will be the optical engine that delivers these benefits into
the 10 Gb/s DWDM market."

EMCORE is conducting private demonstrations of its new Tunable TOSA
technology at the Optical Fiber Communication Conference and Exposition
(OFC) in San Diego on March 24-26. EMCORE plans to begin early sampling to
lead customers within the first half of 2009.
