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.

[edit] Technical details
XFI provides a single lane running at 10.3125 Gbit/s when using a 64B/66B encoding scheme.
[edit] XFI in parlance
XFI is sometimes pronounced as "X" "F" "I" and other times as "ziffie".
[edit] Interworking with XAUI
As of the middle 2006 most 10 gig 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.
