The FC connector has been standardized in TIA fiber optic connector intermateability standard EIA/TIA-604-4. The name "FC" is an acronym for " ferrule connector" or "fiber channel". This third edition cancels and replaces the second edition published in 2006. It is commonly used with both single-mode optical fiber and polarization-maintaining optical fiber. FC connectors are used in datacom, telecommunications, measurement. Fibre Channel (FC) is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data. Fibre Channel networks form a. IEC 61754-13:2024 defines the standard interface dimensions for the type FC-PC family of connectors.
