10 gigabit small form factor pluggable module (XFP)

XFP modules are small, pluggable 10 Gigabit transceivers used in switches and routers of 10 Gigabit Ethernet. They are hot-swappabletransceiver modules that can be replaced during normal operation, have transmission rates of 10 Gbps, and typically operate at wavelengths

of 850 nm, 1,310 nm, and 1,550 nm. They are used in 10 Gigabit Ethernet (10GbE), 40 Gigabit Ethernet (40GbE), 100 Gig

abitEthernet (100GbE), Fibre Channel (FC) as well as Synchronous Optical Networks (SONET) and Synchronous Digital Hierarchy

XFP modules have diagnostic facilities. Their electrical interface specifications, XFI, are part of the XFP MSA, the Multisource Agreement. As an evolution of the XFP module, there is the smaller SFP+ module, which has much smaller dimensions, allowing for higher port density. For Gigabit Ethernet the corresponding interface module is called SFP module(Small Form Factor Pluggable) and for 100 Gigabit Ethernet CFP module (100 Gigabit Small Form Factor Pluggable).
