FC Fiber Optic Connector

FC fiber optic connector is an optical connector with a threaded body, suitable for high-vibration environments. It is usually used for single-mode fiber and polarization-maintaining fiber, and this type of fiber optic connector can be easily seen on the distribution frame. FC fiber optic connectors are currently mainly used in data communications, telecommunications, measurement equipment, and single-mode lasers.
