ClariPhy announces Bookham design win

MARCH 26, 2009 -- ClariPhy says its IC enables the first MLSE-based 10-Gbps SFF 300-pin transponder.

MARCH 26, 2009 -- ClariPhy Communications Inc. (search Lightwave for ClariPhy), a fabless semiconductor company specializing in high-speed communications ICs, has announced that Bookham Inc. (search Lightwave for Bookham), a provider of optical components and modules to the telecom industry, has incorporated ClariPhy's CL1012 clock and data recovery (CDR) IC with maximum likelihood sequence estimation (MLSE) into its new TL9000M small-form-factor (SFF) 300-pin transponder. Bookham announced the launch of its new product at OFC/NFOEC 2009 in San Diego, CA. ClariPhy says its CL1012 IC is the first and only 10-Gbps MLSE product available in single-chip CMOS technology, and provides electronic dispersion compensation (EDC) of impairments inherent to optical fiber in telecom networks.

"The significant performance, cost, size and power dissipation advantages this solution offers have been enabled by the combination of the Bookham indium phosphide building blocks and the MLSE technology provided by ClariPhy. We look forward to delivering significant cost savings to network equipment manufacturers and seeing widespread deployment of this application over a greater percentage of installed fiber routes," says Chris Clarke, vice president of strategy and chief engineer at Bookham.

"We are very excited to contribute to Bookham's milestone product," says Paul Voois, PhD, co-founder and chief executive officer of ClariPhy. "By delivering the proven benefits of MLSE in a small-form-factor 300-pin transponder, Bookham has established a new benchmark in power and performance for dispersion-tolerant modules, and has presented a significant value proposition to telecom equipment providers and carriers. We commend Bookham on its achievement."

The CL1012 IC delivers improved tolerance to chromatic dispersion (CD), polarization mode dispersion (PMD), and nonlinear distortion in a 10x10-mm2 package that dissipates less than 2 W of power. ClariPhy says carriers deploying the CL1012 in their optical modules will realize both opex and capex savings by reducing or eliminating expensive and bulky optical dispersion compensation equipment, avoiding the need for fiber characterization, and enabling the use of a greater percentage of their installed fiber.

ClariPhy will demonstrate its MLSE ICs in a private suite at OFC/NFOEC in San Diego, CA on March 22-26.
