The Fiber Optic Connector is a device which is detachably connected between the optical fiber and the optical fiber. The two end faces of the optical fiber are precisely connected to each other so that the light energy output from the emitted optical fiber can be coupled to the receiving fiber to the maximum extent Its involvement in optical links and the impact on the system to a minimum, which is the basic requirements of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.
Fiber optic connectors can be divided into common silicon-based single-mode and multi-mode connectors, depending on the transmission medium. There are other fiber connectors such as plastic and other media. According to the form of connecting joints can be divided into: FC, SC, ST, LC, D4, DIN, MU, MT, and other forms.
Among them, the ST connector is usually used for wiring equipment, such as fiber patch panels, fiber optic modules, etc .; and SC and MT connectors are usually used for network equipment. According to the shape of the fiber end points are FC, PC (including SPC or UPC) and APC; according to the number of optical core is divided into single and multi-core (such as MT-RJ) points. Fiber optic connectors are widely used and varied. In the actual application process, we generally in accordance with the different structure of the fiber connector to be distinguished.
