An optical fiber jumper (also called a fiber optic patch cord) is a connector inserted at both ends of the optical cable for active optical connection. A plug at one end is called a tail fiber. Fiber optic patch cords are similar to coaxial cables, but without the mesh shield. The center is a glass core through which light travels. It is mainly used to realize the non-permanent fixed connection between equipment, equipment and instrument, equipment and optical fiber and optical fiber in the system. It is an indispensable passive component in optical fiber communication system.

Fiber with rapid development of Internet information at present, due to the high rate, high speed has been widely used, its fiber optic jumper as an important device to realize the connection between optical path activities, has been a data center, the optical fiber to the home, such as local area network is produced by an important guest, since the fiber jumper universal basic knowledge of the most people for fiber optic jumper still exist many problems, Next, the structure, classification, characteristics and application of optical fiber jumper will be deeply understood.
Structure of an optical fiber jumper
In multimode fiber, the diameter of the core is between 50μm and 65μm, roughly the thickness of a human hair. The core diameter of single-mode fiber ranges from 8μm to 10μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the optical fiber inside the core. On top of that is a thin plastic jacket that protects the envelope.
