The Optical Internetworking Forum (OIF) has completed defining the CFP2-ACO (analogue coherent optics) module, used for coherent-based optical transmission. The industry body's CFP2-ACO Implementation Agreement document has been developed to help optical component vendors bring innovative line-side products to market more quickly.

The pluggable CFP2-ACO houses the coherent optics, known as the analogue front end. The components include the tuneable lasers, modulation, coherent receiver, and the associated electronics - the drivers and the trans-impedance amplifier. The Implementation Agreement also includes the CFP2-ACO's high-speed electrical interface connecting the optics to the coherent DSP chip that sits on the line card.
