The optical fiber connector is a device for detachable (movable) connection between an optical fiber and an optical fiber. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. And to minimize the impact on the system due to its intervention in the optical link. 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. various forms.
The following is a detailed description of several commonly used optical fiber connectors in network transmission engineering:
① FC type optical fiber connector: The external strengthening method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (most used on the distribution frame)
② SC-type optical fiber connector: the connector for connecting GBIC optical module, its shell is rectangular, and the fastening method is plug-in latch type, without rotation. (Most used on router switches)
③ ST-type optical fiber connector: commonly used in optical fiber distribution frame, the shell is round, and the fastening method is turnbuckle. (For 10Base-F connection, the connector is usually ST type. Commonly used in optical fiber distribution frame)
④ LC-type optical fiber connector: the connector for connecting the SFP module, which is made by the easy-to-operate modular jack (RJ) latch mechanism. (Routers are commonly used)
⑤ MT-RJ: a square optical fiber connector with integrated transceiver, one end of the dual-fiber transceiver integrated.
