The fiber optic connectors is the removable (active) device connected between the fiber optical cables, make the two optical fiber end face precision to dock, so that the output light energy of transmitter optical cable can be maximize coupling to the receiving fiber optic cable. And make sure its impact can be minimized because of its involvement in the optical link system , which is the basic requirements for fiber optic connectors. To a certain extent, fiber optic connectors also affected the reliability and the performance of fiber optical transmission systems.
Fiber optic connector according to the different transmission media can be divided into common silicon-based optical fiber single-mode and multimode connectors, as well as other issues such as plastic and as the transmission medium of optical fiber connector; connector structure can be divided into: FC,SC, ST, LC, D4, DIN, MU, the MT and so on . The ST connector is usually used to the end of wiring devices, such as fiber optic patch panels, optical transceiver; SC and MT connector typically used for network equipment side. Fiber end shape in the FC, PC (including SPC or UPC) and APC; divided by the number of the fiber core as well as single and multi-core(such as MT-RJ) points. Fiber optic connectors are widely used variety. In practical applications, we generally in accordance with the different structure of the fiber optic connector to be distinguished.
