Types of optical fiber interface connectors
There are many types of fiber optic connectors, that is, the fiber optic connectors that are connected to the optical module, and they cannot be used mutually. People who don’t touch optical fibers often may mistakenly think that the optical fiber connectors of GBIC and SFP modules are the same type, but they are not. The SFP module is connected to the LC fiber optic connector, and the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in network 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 bolt 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. It is often used in optical fiber distribution frames)
④ LC-type optical fiber connector: a connector for connecting SFP modules, which is made of a modular jack (RJ) latch mechanism that is easy to operate. (Routers are commonly used)
⑤ MT-RJ: a square optical fiber connector with integrated transceiver, one end of the dual-fiber transceiver integrated.
