Transceivers (100G QSFP28 + CFP)
The CFP (C Form-factor Pluggable, where C stands for Centum, hundred) MSA is the first industry standard for pluggable 40Gbps and 100Gbps optical transceivers for telecom and datacom application.
CFP transceivers support various protocols (such as 40GbE, 100GbE, OC-768/STM-256, OTU4), media types (multimode and single mode fiber optics and also DWDM). Link distances reach from a few metres to 40km (and beyond). While the electrical connection is based at 4 lanes at 10Gbps (for 40G), respectively 10 x 10 Gbps (for 100G) in each direction, the optical interfaces vary, from supporting duplex single-mode fibers to fiber-ribbons.
