Optical fiber patch cord-Aixton

Optical fiber patch cord(also known as optical fiber connector) means that both ends of the optical cable are equipped with connector plugs to realize the active connection of the optical path; one end with a plug is called a pigtail. Optical Fiber Patch Cord/Cable is similar to coaxial cable, except that there is no mesh shield. In the center is the glass core for light propagation. In a multimode fiber, the diameter of the core is 50 μm to 65 μm, roughly equivalent to the thickness of a human hair. The single-mode fiber core has a diameter of 8 μm to 10 μm. The core is surrounded by a glass jacket with a lower refractive index than the core to keep the fiber inside the core. On the outside is a thin plastic jacket to protect the envelope.
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 reinforcement method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (the most used on the distribution frame)
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. (Most 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) [1]
