“FC” used throughout all applications for Fibre Channel infrastructure and devices, including edge
and ISL interconnects. Each speed maintains backward compatibility at least two previous generations
(I.e., 32GFC backward compatible to 16GFC and 8GFC)
* These numbers are representative of throughput values for the line rate and are payload dependent.

ISLs are usually multi-lane interconnects used for non-edge, core connections, and other high speed applications demanding maximum bandwidth.
ISL’s utilize high bit-rates to accommodate the funneling of edge connections. Some ISL solutions are vendor-proprietary.

Fibre Channel over Ethernet tunnels FC through Ethernet. 10GFCoE was not available until after FC-BB-5, the FCoE protocol standard, was completed in 2007. For compatibility, all 10GFCoE FCFs and CNAs are expected to use SFP+ devices, allowing the use of all standard and non-standard optical technologies and additionally allowing the use of direct connect cables using the SFP+ electrical interface. FCoE ports otherwise follow Ethernet standards and compatibility guidelines.
