CFP8 400Gbps Transceiver Module

CFP8 400Gbps Transceiver Module

This is a proposal for a new 400G Form Factor: CFP8
The proposed CFP8 form factor is ~CFP2 size but supports 4x100G and 400G, i.e. 4x the CFP2’s 1x100G
The CFP8 name follows the CFP2 and CFP4 naming convention of suffix designating relative bandwidth density
The CFP8 uses a new 16x25G electrical I/O connector
CFP8 Electrical I/O and Optical specifications are deferred to other standards organizations like IEEE and ITU-T
Example IEEE specifications supported by CFP8:

400GBASE-SR16 parallel MMF (16x25G NRZ)
400GBASE-FR8/LR8 duplex SMF (8x50G PAM4 WDM)
400GBASE-DR4 parallel SMF (4x100G PAM4)
