CWDM8 MSA targets compact lower power optics for 400G

The CWDM8 multi-source agreement (MSA) Group has been formed to define optical specifications for 400G singlemode optics using 50G per wavelength and non-return-to-zero (NRZ) optical modulation.

The consortium aims to address what they see as a near-term need for lower power and more cost-effective options for distances of 2km and 10km within data centre and campus networks. This will support the deployment of 12.8Tb/s Ethernet switches and other advanced networking equipment with 50G electrical I/O.

Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
