Optical fiber connectors are increasingly used in various fields as an essential part of optical fiber communication, and optical fiber connector products on the market are more in variety at present, and the packaging materials of the connector outer shell are divided into plastics and metals. The plastic connector has poor mechanical and environmental adaptability, and the optical fiber connector packaged by the metal shell has good environmental adaptability.

The LC type connector is a kind of optical fiber connector, and is a kind of small connector type because the external size is only half of the SC/ST/FC connector. LC type connectors are widely used in integrated wiring system engineering.

LC-type connectors are the type of fiber optic connectors developed by the well-known Bell research institute and are made using a modular jack latching mechanism that is easy to operate. The size of the pin and the sleeve is half of the size used by common SC, FC and the like, and is 1.25 mm. This may increase the density of fiber optic connectors in the optical fiber distribution frame. Currently, LC-type connectors have actually taken a leading position in single-mode SFF, and applications in multi-mode have grown rapidly.
