The main structure of the optical fiber jumper.
Optical fiber jumper (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. Fiber optic jumpers are similar to coaxial cables, except that there is no mesh screen.
In the center is the glass core through which light propagates. In a multimode fiber, the diameter of the core is 50μm~65μm. The single-mode fiber core has a diameter of 8 μm to 10 μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the optical fiber in the core. On the outside is a thin plastic jacket to protect the envelope.
The fiber jumper is the fiber connector that is connected to the optical module. There are 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 simple analysis of several commonly used optical fiber connectors in network engineering:
1. FC 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, the most used on the distribution frame.
2. SC type optical fiber jumper: the connector that connects to 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.
3. ST-type optical fiber jumper: often used in optical fiber distribution frame, the outer shell is round, and the fastening method is turnbuckle. For 10Base-F connections, the connector is usually of the ST type. Commonly used in optical fiber distribution frames.
4. LC-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.
