Fiber optic jumpers are used to make jumpers from equipment to fiber optic cabling links. There is a thicker protective layer, which is generally used in the connection between the optical transceiver and the terminal box, and is used in some fields such as optical fiber communication systems, optical fiber access networks, optical fiber data transmission, and local area networks.
Optical fiber jumpers (also known as optical fiber connectors), that is, optical fiber connectors connected to optical modules, are also available in many types, and they cannot be used mutually. 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:
①FC-type optical fiber jumper: 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).
②SC type optical fiber jumper: the connector for connecting the GBIC optical module, its shell is rectangular, and the fastening method is a plug-in latch type without rotation. (Most used on router switches).
③ST type optical fiber jumper: 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).
④LC-type optical fiber jumper: the connector for connecting the SFP module, which is made of a modular jack (RJ) latch mechanism that is easy to operate. (Routers are commonly used).
