What type of head is a 5-meter fiber optic FC-FC

A 5-meter fiber optic FC-FC cable has FC (Ferrule Connector) heads on both ends, featuring threaded coupling and a 2.5 mm ferrule for secure, low-loss connections.Connector Type and FeaturesThe FC connector is a fiber-optic connector designed for high-precision and high-vibration environments, such as telecommunications, datacom, measurement equipment, and single-mode lasers . It uses a threaded body to prevent accidental disconnection and ensure stable alignment. The fiber end is embedded in a 2.5 mm ferrule, typically made of zirconia ceramic or stainless steel, which is polished to a physical contact (PC) surface to minimize insertion loss and back-reflection .Polish TypesFC connectors can have different polish grades:FC/PC (Physical Contact): Standard polish for general useFC/SPC (Super Physical Contact): Higher precision, lower insertion lossFC/UPC (Ultra Physical Contact): Ultra-low back-reflection, ideal for sensitive optical systems ApplicationsFC-FC patch cords are commonly used in:Single-mode fiber networksPolarization-maintaining fiber systemsHigh-vibration industrial or laboratory environmentsOptical test equipment and laser systems Cable LengthThe 5-meter length indicates the distance between the two FC connectors, suitable for connecting devices within racks, labs, or short-distance network setups. The FC-FC configuration ensures that both ends have the same connector type, providing compatibility with equipment ports designed for FC connectors . In summary, a 5-meter FC-FC fiber optic cable has threaded FC connectors on both ends with 2.5 mm ferrules, designed for secure, low-loss connections in high-precision or high-vibration applications.
