A high-speed data link planned to run up to 2 Gbps on a fibre optic cable. A number of manufacturers are developing products to use the fibre Channel-Arbitrated Loop (FC-AL) serial storage interface at 1 Gbps so that storage devices such as hard discs can be connected.

Supports signalling rates from 132.8 Mbps to 1,062.5 Mbps, over a mixture of physical media including optical fiber, video coax, miniature coax, and shielded twisted pair wiring. The standard supports data transmission and framing protocols for the most popular channel and network standards including SCSI, HIPPI, Ethernet, Internet Protocol, and ATM.
