The SFP is a small, hot-swappable optical transceiver for optical communication applications in telecommunications and data communications. SFP connects motherboards and optical or UTP cables of network devices such as switches and routers. SFP is an industry specification supported by some fiber optic device providers. SFP transceivers support SONET, Gigabit Ethernet, Fibre Channel, and a few other communication standards. This standard extends to SFP+ and supports 10.0 Gbit/s transmission rates, including 8 gigabit Fibre Channel and 10GbE. The SFP+ module version of the fiber and copper versions has been introduced. Compared with the Xenpak, X2 or XFP versions of the module, the SFP+ module leaves part of the circuit in the motherboard implementation instead of the module.
