High Quality Content by WIKIPEDIA articles! The XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable, protocol-independent optical transceiver, typically operating at 850nm, 1310nm or 1550nm, for 10 Gigabit per second SONET/SDH, Fibre Channel, gigabit Ethernet, 10 gigabit Ethernet and other applications, including DWDM links. It includes digital diagnostics similar to SFF-8472 but more extensive, that provide a robust management tool.The XFI electrical interface specification is a portion of the XFP Multi Source Agreement specification.
High Quality Content by WIKIPEDIA articles! The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is a popular industry format supported by many network component vendors. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. The standard is expanding to SFP+ which will be able to support data rates up to 10.0 Gbit/s (that will include the data rates for 8 gigabit Fibre Channel, and 10GbE. SFP+ module versions for optics as well as copper are being introduced. In comparison to Xenpak, X2 or XFP type of modules, SFP+ modules leave some of the circuitry to be implemented on the host board instead of inside the module.)
