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.
