Fiber optic connectors are designed to connect optical fibers. They allow to switch and connect optical lines. Thanks to the highest quality optical connectors the lowest attenuation is guaranteed. Each connector is different, depending on the type of optical fiber and the size and polishing method of the ferrule. Ferrula is a tube, which is made of ceramic sinter and it is a cover and guide for optical fiber in connector.SC type fiber optic connectors are designed for termination of fiber optic cables and fibers. Currently one of the most popular fiber optic connectors. They are characterized by a "push-pull" locking mechanism that guarantees a quick realization of the connection and stable connection. The correct placement of the SC type fiber optic plug in the adapter is signaled by a characteristic clicking sound. Used for singlemode and multimode transmission.
