The fiber connector types, sometimes referred to as terminations, link fiber optic cables together through terminals, switches, adapters, and patch panels, by bridging the gap between their internal glass fibers that transmit the data down the length of the cable. Among these components, fiber connector types are essential to network performance, reliability, and scalability. In this. Functions of Fiber Optic Connectors and Adapters (1) Can form a continuous optical path (2) Repeatable loading and unloading (3) Actively connected with active or passive devices (4) Active connection with systems and instruments Widely used in long-distance trunk network, metropolitan area.
