FC Fiber Optic Connector
FC fiber optic connectors use a keyed threaded coupling for secure, repeatable mating in telecom equipment, optical test systems, industrial networks, and measurement links. Single-mode UPC or APC and multimode UPC versions are available with narrow-key or wide-key interfaces and boots sized for buffered fiber and common cable diameters.
To identify the right model, confirm the assembly state, fiber and polish, key width, cable or buffer diameter, boot color, and required quantity.
A fiber optic connector must match both the mating interface and the cable being terminated. Confirm connector family, fiber and polish, format, cable or buffer diameter, boot, assembly method, and inspection requirements together. Read the fiber optic connector buying guide
