Fiber sc connector SC stands for Subscriber Connector. SC, also called a square connector, was developed by Nippon Telegraph and Telephone in the market, slowly grew in popularity as manufacturing cost went down. Now Fiber sc connector is becoming increasingly popular in single mode Fiber optic connector cable, analog CATV, GPON, GBIC. SC is a snap (push-pull coupling) connector with a 2.5mm ferrule diameter that operates on the standard IEC 61754-4. The connector’s outer square profile together with its snap coupling mechanism that allows greater connector packaging density in instruments and patch panels.

FC Fiber Optic Connector: FC is short for Ferrule Connector. It is a round, threaded fiber optic connector that was designed by Nippon Telephone and Telegraph in Japan. The Fiber optic connector is applied for single-mode optic fiber and polarization-maintaining optic fiber. The FC  is a screw type connector with a 2.5mm ferrule, which was the first fiber optic connector to use a ceramic ferrule. However, FC is becoming less common and mostly replaced by SC and LC because of its vibration loosening and insertion loss.
