Nine companies have joined forces to create a 40Gbit/s optical transceiver standard. Dubbed the x40 multi-source agreement group, the firms are targeting the interface at telecom and datacom applications, supporting distances up to 10km.
By integrating four 10Gbit/s transmit and four receive channels, multiplexed over a fibre pair, the standard exploits components for the high-volume 10Gbit/s transceiver market to address 40Gbit/s applications.
"This MSA enables 40G. It will spur others to develop the 40G serial products," says Daryl Inniss, vice president of Ovum-RHK's Communication Components research. "As more 40G gets out there, albeit in the form of parallel muxing, the market will demand more 40G."
Equipment vendors supporting the x40 MSA include Infinera and Juniper. Infinera is interested in 40Gbit/s and has already demonstrated in the lab a 40 x 40Gbit/s photonic integrated circuit. However, the current MSA only has a 10km reach. Juniper is interested in the x40 MSA as a high-speed router interface.
Both Juniper's and Cisco's routers already have 40Gbit/s interfaces but these are serial 40G and will not be compatible with the new MSA.
