The classification and overview of fiber optic jumpers are as follows
There are many kinds of optical fiber jumpers (also known as optical fiber connectors), that is, optical fiber connectors connected to optical modules, and they cannot be used interchangeably. The SFP module is connected to an LC fiber optic connector, while the GBIC is connected to an SC fiber optic connector. The following is a detailed description of several commonly used fiber optic connectors in network engineering:
① FC fiber optic jumper: The external method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (mostly used on distribution frames)
②SC type optical fiber jumper: the connector connected to the GBIC optical module, its shell is rectangular, and the fastening method is a plug-in pin-bolt type, which does not need to be rotated. (Mostly used on router switches)
③ST type optical fiber jumper: commonly used in optical fiber distribution frames, the outer shell is round, and the fastening method is a turnbuckle. (For 10Base-F connection, the connector is usually ST type. Commonly used in fiber distribution frame)
④ LC-type fiber optic jumper: the connector connected to the SFP module, which is made of a modular jack (RJ) latch mechanism that is easy to operate. (Commonly used by routers) Fiber jumper FC LC ST SC single-mode single-core yellow and white fiber optic cable pigtail
