Optical fiber patch cord (also known as optical fiber connector) refers to a connector plug installed at both ends of the optical cable, used to achieve active connection of the optical path; if one end has a plug, it is called a tail fiber. Optical fiber patch cord (Optical Fiber Patch Cord/Cable) is similar to coaxial cable, except that it does not have a mesh shielding layer. The center is the glass core for light propagation. In multimode fiber, the diameter of the core is 50μm to 65μm, roughly equivalent to the thickness of a person's hair. While in single-mode fiber, the diameter of the core is 8μm to 10μm. The outside of the core is surrounded by a layer of glass with a lower refractive index to keep the fiber within the core. The outer layer is a thin plastic jacket for protection.

The classification and overview of optical fiber patch cords are as follows:

Optical fiber patch cord (also known as optical fiber connector), which is the optical fiber connector for the access optical module, has many types and cannot be interchanged with each other. The SFP module connects to the LC optical connector, while the GBIC connects to the SC optical connector. The following is a detailed explanation of several commonly used optical connectors in network engineering:

① FC type optical patch cord: The external reinforcement method is to use a metal sleeve, and the fastening method is a screw clip. It is generally used on the ODF side (the most commonly used on the distribution frame)

② SC type optical patch cord: The connector for connecting GBIC optical modules, its shell is rectangular, the fastening method is plug-in latch type, no rotation required. (Mostly used in routers and switches)

③ ST type optical patch cord: Often used in optical distribution frames, the shell is circular, the fastening method is a screw clip. (For 10Base-F connections, the connector is usually the ST type. Mostly used in optical distribution frames)
