The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications.
The form factor and electrical interface are specified by a multi-source agreement (MSA). This interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fibre optic or copper networking cable. It is a popular industry format jointly developed and supported by many network component vendors.
SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.
