EMCORE reveals tunable TOSA 10G optical component platform

MARCH 26, 2009 -- The company believes its technology will deliver density, flexibility, and cost benefits into the 10-Gbps DWDM market.

MARCH 26, 2009 -- EMCORE Corp. (search Lightwave for EMCORE), a provider of compound semiconductor-based components and subsystems for the fiber-optic and solar power markets, plans to release a new full-band tunable transmit optical subassembly (TOSA) product line.

The tunable TOSA product line combines EMCORE's tunable external-cavity laser technology with a co-packaged Mach-Zehnder modulator. The TOSA tunes across more than 90 channels on the 50-GHz ITU grid. With low power consumption, it is compatible with existing XFP module and line-card requirements. The company also says its product boasts optical performance similar to existing technologies using discrete tunable laser and external lithium-niobate modulator. EMCORE believes this new TOSA will allow for the migration of existing 300-pin MSA modules to smaller and pluggable form factors.

Stephen Krasulick, vice president and general manager of EMCORE's Fiber Optics Division, says, "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-Gbps DWDM market."

EMCORE is conducting private demonstrations of its new tunable TOSA technology at OFC/NFOEC 2009 in San Diego on March 24-26. It plans to begin early sampling to lead customers within the first half of 2009.
