ClariPhy Enables Terabit Line Cards with World’s First Integrated CFP2-ACO Coherent Reference Platform

News Highlights:

  • World’s first reference design for high-density (up to 1 Terabit per second or 1T) coherent optical line cards using compact CFP2-ACO pluggable transceivers
  • Based on ClariPhy’s world’s first 28nm 100/200G coherent DSP, only product shipping in production
  • Plug and play support for new high density, low power CFP2-ACO modules from industry leading suppliers Finisar and Oclaro
  • Superior performance for line card designs for long haul, metro, cloud and datacenter interconnects; fast time-to-market, reducing cost of development and design complexity

IRVINE, Calif. — (BUSINESS WIRE) — March 24, 2015OFC 2015 ClariPhy Communications, a leading developer of ultra-high-speed systems-on-chip (SoCs) for data networking, today announced it will demonstrate at this week’s Optical Fiber Conference (OFC) the world’s first integrated CFP2-ACO coherent single-board reference design, containing its CL20010 200 gigabit per second (200G) SoC and a CFP2-ACO slot supporting pluggable transceivers from leading ecosystem partners. Supporting both 100G and 200G line rates, the CL20010 enables high density (up to 1T) optical transport infrastructure line cards that can be used to accelerate Internet bandwidth for data centers, transport infrastructure and cloud-based networks.

The arrival of solutions supporting the small CFP2-ACO form factor is expected to greatly increase density and performance for applications such as data center interconnects and metro/regional packet optical transport networks, while delivering the proven advantages of pluggable transceivers such as cost, scalability and interchangeability. The complexities of the linear interface between the coherent DSPs and pluggable optical modules have presented a challenge to the industry, requiring considerable attention to design limits and performance. ClariPhy’s integrated 100G/200G CFP2-ACO reference platform solves that challenge and will stimulate next generation designs with proven schematics and layout files allowing faster time-to-market and lower risk for its customers.

ClariPhy has worked closely with the industry’s top module suppliers on reference design development to ensure compatibility while optimizing performance in full support of the Optical Internetworking Forum’s (OIF’s) CFP2-ACO Implementation Agreement. The design migrates two boards into a single PCB reference platform for companies to easily design their own line cards while enabling CFP2-ACO skew control, preemphasis and calibration to streamline the manufacturing of optical line cards.

ClariPhy is delivering to customers a proven design integrating the CL20010 and CFP2-ACO module. By providing the reference design schematic, Gerber layout files and other pertinent line card development documentation, it significantly reduces time to market, development cost and engineering guess work.

Product Details

ClariPhy’s LightSpeed-II CL20010 28nm multimode SoC offers unprecedented levels of integration, performance and software defined networking (SDN) capabilities that allow the network to adapt in changes in traffic growth and reach automatically. Its innovative design includes support for 100G/200G 16QAM modulation on a single wavelength, which enables 400G dual-carrier super channels in 75GHz of DWDM spectrum, increasing fiber capacity by 170% and reducing cost per bit by 50% versus today’s 100G coherent systems. The advanced equalization algorithms enable both devices to overcome the impairments of the channel, including chromatic dispersion, polarization mode dispersion and non-linearities. Support for standard 100G QPSK modulation with the industry’s best OSNR performance provides carriers the flexibility of using a single, software programmable line card for 100G, 200G and 400G transmission at distances exceeding 3500 kilometers.


ClariPhy will demonstrate and will make available its CFP2-ACO coherent reference platform at OFC in Los Angeles, March 24-26, 2015. The 28nm CL20010 is shipping in production to multiple OEM customers, and has undergone successful trials at several Tier-1 carriers.
