==Supported signals==

===Digital===

CFP transceivers can support a single 100 Gbit/s signal like [[100 Gigabit Ethernet|100GbE]] or [[Optical Transport Network|OTU4]] or one or more 40 Gbit/s signals like 40GbE, [[OTU3]], or [[STM-256]]/[[OC-768]].

===Analog===

The [[Optical Internetworking Forum]] in 2016 published the CFP2-ACO or CFP2 - Analog Coherent Optics Module Interoperability Agreement (IA). This IA supports a configuration where the [[digital signal processor]] (DSP) is on the main board and analog optical components are on the module. This IA is useful in the case when the DSP exceeds the module power envelope.<ref>{{Cite web|url=http://www.oiforum.com/wp-content/uploads/OIF-CFP2-ACO-01.0.pdf |title=OIF-CFP2-ACO-01.0 |date=2016-01-22 |accessdate=2017-05-08}}</ref>

The ACO interface can be used in coherent optics applications when the link delivers a flexible amount of bandwidth to the system, for example when combined with [[FlexE]]. The initial ACO IA is for the CFP2 module.
