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.)

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! XFI is a 10 gigabit per second chip-to-chip electrical interface specification defined as part of the XFP multi-source agreement. It was developed by the XFP MSA group. XFI's principal applications are for 10 Gigabit Ethernet, 10 Gigabit/sec Fibre Channel, SONET OC-192, SDH STM-64, 10 Gigabit/sec OTN OTU-2, and parallel optics links. XFI provides a single lane running at 10.3125 Gbit/s when using a 64B/66B encoding scheme. XFI is sometimes pronounced as "X" "F" "I" and other times as "ziffie". As of 2009[update] most 10 Gigabit Ethernet products use XAUI interface that has four lanes running at 3.125Gbit/s using 8B/10B encoding. Most 10 Gigabit Ethernet Products require a SerDes device to make the transition from XAUI to XFI. Some 10 GbE devices have an integrated both XAUI and XFI capabilities.
