C Form-factor Pluggable
Encyclopedia
The C form-factor pluggable (CFP) is a multi-source agreement to produce a common form-factor for the transmission high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum), as the standard was primarily developed for 100 Gigabit Ethernet
systems.
In March 2009, Santur demonstrated a 100 Gigabit pluggable CFP Transceiver prototype, Santur 100G CFP Transceiver
or one or more 40 Gbit/s signals like 40GbE, OTU3, or STM-256/OC-768.
100 Gigabit Ethernet
40 Gigabit Ethernet, or 40GbE, and 100 Gigabit Ethernet, or 100GbE, are high-speed computer network standards developed by the Institute of Electrical and Electronics Engineers . They support sending Ethernet frames at 40 and 100 gigabits per second over multiple 10 Gbit/s or 25 Gbit/s lanes...
systems.
CFP standardization
The CFP transceiver is specified by a multi-source agreement (MSA) between competing manufacturers. The CFP was designed after the SFP interface, but is significantly larger to support 100Gb using 10 lanes in each direction (RX, TX) with 10Gb/s each.In March 2009, Santur demonstrated a 100 Gigabit pluggable CFP Transceiver prototype, Santur 100G CFP Transceiver
Supported signals
CFP transceivers can support a single 100 Gbit/s signal like 100GbE or OTU4Optical Transport Network
ITU-T defines an Optical Transport Network as a set of Optical Network Elements connected by optical fibre links, able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of optical channels carrying client signals...
