ST Fiber Optic Connector
ST fiber optic connectors use a quarter-turn bayonet interface for fast, positive engagement in industrial networks, campus backbones, security systems, instrumentation, and installed fiber infrastructure. Single-mode and multimode UPC versions are available with boots sized for buffered fiber and common cable diameters.
To identify the right model, confirm the assembly state, fiber and polish, 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
