光纤信道（Fibre Channel，简称FC）是一种高速网络互联技术（通常的运行速率有2Gbps、4Gbps、8Gbps和16Gbps），主要用于连接计算机存储设备。光纤信道由信息技术标准国际委员会（INCITS）的T11技术委员会标准化。INCITS受美国国家标准学会（ANSI）官方认可。过去，光纤信道大多用于超级计算机，但它也成为企业级存储SAN中的一种常见连接类型。尽管被称为光纤信道，但其信号也能在光纤之外的双绞线上运行。

光纤信道协议（Fibre Channel Protocol，FCP）是一种类似于TCP的传输协议，大多用于在光纤信道上传输SCSI命令。

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. Fibre Channel is standardized in the T11 Technical Committee of the International Committee for Information Technology Standards (INCITS), an American National Standards Institute (ANSI)-accredited standards committee. Fibre Channel was primarily used in supercomputers, but has become a common connection type for storage area networks (SAN) in enterprise storage. Despite its name, Fibre Channel signaling can run on an electrical interface in addition to fiber-optic cables.
