According to the different transmission media, optical fiber connectors can be divided into common single-mode and multi-mode connectors of silicon-based optical fiber, and others, such as

Docking principle of optical fiber connector

The optical fiber connector with glue as transmission medium can be divided into FC, SC, St, LC, D4, DIN, mu, MT and other forms according to the structure of connector. Among them, St connector is usually used for wiring equipment end, such as fiber distribution frame, fiber module, etc.; while SC and MT connector are usually used for network equipment end. There are FC, PC (including SPC or UPC) and APC according to the end face shape of optical fiber; there are single core and multi-core (such as MT-RJ) according to the number of optical fiber cores. Fiber optic connectors are widely used and of various kinds. In the process of practical application, we usually distinguish according to the different structure of optical fiber connector. Here are some common fiber connectors
