EXFO and CoreOptics To Demonstrate First 40G Coherent Transponder Module at OFC/NFOEC 2010

March 18, 2010 – CoreOptics Inc. and EXFO Inc. will jointly demonstrate the first 40G coherent transponder module from CoreOptics and EXFO’s FTB-8140 Transport Blazer test module at OFC/NFOEC 2010, says a company official. The live demonstration achieves 40G error-free traffic on a next-generation multihaul DWDM line card, using EXFO’s 40G Transport Blazer client-side test module with CoreOptics’ 40G CP-QPSK line-side transponder. The 40G CP-QPSK includes advanced dual polarization, DQPSK modulation, and coherent detection with digital signal processing (DSP) technologies.

The live demo will comprise a test setup of EXFO’s FTB-8140 Transport Blazer (40G/43G) generating an OC-768/STM-256 signal with PRBS (pseudo-random bit stream) test patterns into a next-generation multihaul DWDM platform’s line card with its integrated client 40G VSR module, FEC ASIC, and line-side 40G CP-QPSK DWDM module. The transmitted output from the CoreOptics module will connect to a line system with EDFAs and 2000 km of singlemode fiber, back to the receiver end.

EXFO’s FTB-8140 module offers 40G SONET/SDH and 43G OTN line rates as part of the Transport Blazer family of modules, which also includes the FTB-8130NGE 10G multiservice module. This combined 40G commissioning and service turn-up system offers a wide range of testing rates, applications, and technologies, meeting today’s 40G ROADM-based, converged network requirements. Supported technologies include DSn/PDH, SONET/SDH, OTN (optical transport network) with FEC testing as per ITU-T G.709, Ethernet, and Fibre Channel.

The CoreOptics 40 Gbit/s Coherent-Polarized QPSK (CP-QPSK) DWDM transponder CO40TDL40 supports dual polarization, DQPSK modulation, and coherent detection with DSP technologies. Coherent detection with polarization-multiplexed DQPSK technology improves receiver sensitivity and compensates for optical dispersion, resulting in cost savings and optical performance when migrating 40G and 100G networks.
