LONDON, UNITED KINGDOM -- (Marketwired) -- 09/23/13 --
ClariPhy Communications, Inc., a leading developer of ultra-high speed systems-on-chip (SoCs) for coherent optical networks, announced today the availability of a reference design for coherent optical transmission supporting 200 gigabit per second (200G) 16QAM modulation. The reference design -- developed in close collaboration with ClariPhy's ecosystem partners Fujitsu Optical Components, Inphi, NeoPhotonics, and u2t Photonics -- performs electrical-to-optical (E2O) and optical-to-electrical (O2E) conversion and is intended for use with ClariPhy's Lightspeed™ family of coherent SoCs. ClariPhy's next generation 28nm CMOS Lightspeed coherent SoC will support both 100G and 200G data rates. ClariPhy and its ecosystem partners are working together to optimize performance of the optical reference design when coupled with this SoC, offering OEMs a highly integrated, fast time to market solution that addresses rapidly growing demand for 200G and 400G coherent transmission.
100G coherent has become the technology of choice for dense wavelength division multiplexing (DWDM) transmission in long haul optical networks. As carriers seek to deploy coherent technology in cost-sensitive metro networks as well, they require cost-effective solutions. The use of 200G 16QAM modulation enables such a solution, delivering double the bandwidth over the same coherent optics used for 100G and effectively cutting cost per bit in half. Furthermore, future 400G Ethernet router deployments will drive the need for 400G DWDM transport, which can be achieved using two wavelengths of 200G 16QAM in a superchannel configuration.
ClariPhy's optical reference design includes the following best in class components: Fujitsu Optical Components' FTM7977HQA lithium niobate modulator; Inphi's IN3214SZ quad linear modulator driver; two NeoPhotonics' ITLA3100 integrated tunable laser assemblies (ITLAs), one for the transmitter and one for the local oscillator; and u2t Photonics' CPRV1222A integrated coherent receiver (ICR). Together these components meet the exacting bandwidth, linearity and phase noise specifications required to support 200G 16QAM modulation. A high performance GPPO interface provides connectivity to a separate coherent electrical transmitter and receiver, such as ClariPhy's 28nm digital-to-analog converter (DAC) and analog-to-digital converter (ADC) evaluation board, which is currently shipping to OEMs. ClariPhy's ADC and DAC deliver the ENOB, bandwidth and jitter performance necessary for 100G QPSK and 200G 16QAM modulation, which will both be supported in its next-generation Lightspeed SoC. This modular solution comprising both electrical and optical coherent reference boards will enable ClariPhy and its ecosystem partners to tune the programmable parameters of the Lightspeed SoC and optical components for optimum transmission performance, minimizing integration time and accelerating time to market for OEMs and module suppliers who incorporate the solution into their systems.
