The 4WDM MSA (4-wavelength Wavelength Division Multiplexing Multi-Source Agreement) Group has been formed as an industry consortium dedicated to defining optical specifications and promoting adoption of interoperable 100G (4x25G) optical transceivers for 10 km distances, based on the CWDM4 wavelength grid, and for 20 km and 40 km distances, based on the LAN-WDM wavelength grid, over duplex single-mode fibre (SMF).
The Group says these extended reaches are important for modern data centre interconnects and mobile backhaul applications. The 4WDM MSA participants are responding to previously unmet industry needs for longer reaches, lower costs, and lower power consumption, as compared to previously available standards, in small form factors.
“The CWDM4 MSA defined the first duplex low cost 100G specification for 2 km reaches based on a CWDM grid and using RS (528,514) FEC. Now the 4WDM MSA is extending the value proposition of the CWDM4 MSA and RS-FEC to define an even more cost-effective set of specifications for reaches from 10 to 40 km. Customers, particularly hyperscale cloud service providers and carriers, are looking for optimised solutions for up to 40 km,” commented Dale Murray, Principal Analyst, LightCounting Market Research.
Founding members of the 4WDM MSA include Broadcom Limited, Brocade, Ciena, ColourChip, Dell Inc., Finisar Corporation, Foxconn Interconnect Technology, Huawei Technology Co., Ltd., Intel Corporation, Juniper Networks, Kaiam Corp., Lumentum, MACOM Technology, Oclaro Inc., Skorpios Technologies Inc., Source Photonics, and Sumitomo Electric Industries Ltd.
