Common Fiber Connectors

Optical fiber connector is a device for detachable (movable) connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. And to minimize the impact on the system due to its intervention in the optical link, this is the basic requirement of the fiber optic connector. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.

Optical fiber connectors can be divided into common silicon-based optical fiber single-mode and multi-mode connectors according to different transmission media, and other optical fiber connectors such as plastics as transmission media; according to the structure of the connector, it can be divided into: FC , SC, ST, LC, D4, DIN, MU, MT, etc. in various forms. Among them, ST connectors are usually used at the wiring equipment end, such as optical fiber distribution frames, optical fiber modules, etc.; while SC and MT connectors are usually used at the network equipment end. According to the shape of the fiber end face, there are FC, PC (including SPC or UPC) and APC; according to the number of fiber cores, there are single-core and multi-core (such as MT-RJ).
