– Fibre Channel, or FC, is a high-speed network technology (commonly running at 2-, 4-, 8- and 16-gigabit per second rates) primarily used to connect computer data storage
– When the technology was developed, it supported only optical cabling (fiber). At some point support for copper cables was added, so the development committee decided to keep the same name but switch to the British English spelling fibre for the standard. The American English spelling fiber refers only to optical cabling. Thus, a network using fibre can be implemented either with copper or optical fiber.
