Fiber optic patch cords are used to make patch cords 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 industries such as optical fiber communication systems, metal transmission networks, metal transmission data and its local area network.

The following are several types of sockets commonly found in network engineering:

①FC type optical fiber jumper: The external strengthening method is to use a metal sleeve, and the tightening method is a turnbuckle. Generally used on the ODF side (more used on fiber optic distribution frames)

②SC type optical fiber jumper: the connector for connecting the GBIC optical fiber module, its casing is a rectangular frame, and the tightening method is to use the plug-in bolt type, and it is not necessary to rotate. (more used on wireless router network switches)

③ST type optical fiber jumper: common in optical fiber distribution frame, the casing is round, and the tightening method is turnbuckle. (For 10Base-F connection, the connector is usually ST type. Commonly used in fiber optic distribution frames)

④LC-type fiber jumper: the connector for connecting the SFP control module, it adopts the modular design socket (RJ) latch principle which is easy to operate. (Common with wireless routers)
