Seeking a path beyond pluggable modules

Enabling on-board and co-packaged optics requires photonic integrated circuits and silicon photonics, but the exact format is yet to be established, finds Andy Extance

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.
