The Optical Internetworking Forum has started specification of a new analogue coherent optics specification that will fit within a CFP8 pluggable module. The CFP8 is the latest is a series of optical modules specified by the CFP Multi-Source Agreement and will support the emerging 400 Gigabit Ethernet standard.

The analogue coherent optics (ACO) module is used for optical transport. The CFP module integrates the optics and driver electronics while the accompanying coherent DSP-ASIC resides on the line card. This enables systems vendors to use their own DSP-ASICs while choosing the coherent optics from the various module makers.
