NEC Selects ClariPhy's LightSpeed 40G coherent SoC

ClariPhy Communications, Inc., a developer of high-speed mixed signal, digital signal processing (MXSP) chips for coherent optical networks, says its LightSpeed coherent system-on-chip (SoC) has been selected for integration into NEC Corp.'s optical transceiver modules.

ClariPhy Communications, Inc., a developer of high-speed mixed signal, digital signal processing (MXSP) chips for coherent optical networks, says its LightSpeed coherent system-on-chip (SoC) has been selected for integration into NEC Corp.'s optical transceiver modules.

ClariPhy's LightSpeed CL4010 is an application specific standard product (ASSP) for coherent optical transmission, which enables module suppliers like NEC to address demand for 40G coherent deployments.

This is the third announced customer for ClariPhy's 40G chip technology, following Oclaro and, most recently, JDSU (see "JDSU offers 8500 series 40-Gbps coherent transponder").

The LightSpeed CL4010 SoC is the industry's first single-chip CMOS solution targeting the deployment of 40G coherent optical networks, according to ClariPhy. The company says it offers industry leading integration and lower power consumption compared to alternative products, enabling module makers to use standard multi-source agreement (MSA) form factors. The chip also supports ultra-long haul transmission of more than 3,000 km, while providing a high degree of spectral efficiency for metro and long-haul networks.

"The single-chip integration of the LightSpeed SoC enables us to build standard form-factor optical transceiver modules with digital coherent technology," said Tomokazu Ito, general manager, fiber optics devices division, NEC Corporation. "The superior performance delivered by the LightSpeed SoC coupled with compatibility with widely deployed enhanced forward error correction solutions helps us significantly increase optical reach compared to current products."

ClariPhy and NEC will demonstrate NEC's optical transceiver modules based on LightSpeed CL4010 SoC at the OFC/NFOEC event in Los Angeles from March 5—8, 2012. The demonstration will be accessible by invitation only.
