LightSpeed-II CL20010 offers programmable modulation critical in deployment of software defined networks supporting 200G, and 100G transport.

Irvine, CA– ClariPhy Communications has announced that it is sampling its LightSpeed-II CL20010 SoC to customers for 200G and 400G dense wavelength division multiplexing (DWDM) transport applications. The CL20010 supports single-carrier 200G transmission using 16QAM modulation, which when combined with its integrated transmit filtering capabilities, enables dual-carrier 400G superchannels on 75GHz DWDM spacing. This represents a fiber capacity increase of 170% versus today’s 100G coherent systems while reducing cost per bit by nearly half, presenting a compelling value proposition to carriers who are increasingly gearing up for 200G and 400G deployments. As a standard product that is generally available to the industry, the 28nm CMOS SoC will expand carriers’ choice of 200G and 400G suppliers beyond the few OEMs who have developed the technology internally, while redefining the state of the art in performance and power efficiency.

The CL20010 acts as a single chip OTN muxponder, multiplexing two independent 100G client signals (either OTU4 or 100G Ethernet) onto a single DWDM wavelength over the same optics that are used for 100G coherent transmission. The SoC offers additional advanced features like high-gain soft decision forward error correction (SDFEC), digital transmit filtering supporting flexible grid DWDM, and high-performance carrier recovery that provides the robustness to phase noise that is required with 16QAM modulation. Furthermore the CL20010 supports standard 100G QSPK modulation, providing carriers with the flexibility of using a single, software programmable line card for 200G and 400G transmission at reaches exceeding 600km and 100G transmission exceeding 3500km.

ClariPhy is shipping a 200G coherent reference design based on the CL20010 and optical components from its ecosystem partners. (See "ClariPhy Announces 200G Coherent Optical Reference Design in Collaboration with Ecosystem Partners at ECOC 2013".)  Additionally, ClariPhy is collaborating with leading pluggable optical module suppliers and with the Optical Interworking Forum (OIF) to ensure compatibility and highest performance with the coherent CFP2 implementation agreement that is under development in the OIF.
