Wiring. It has a thick protective layer and is generally used in the connection between the optical terminal and the terminal box.

Fiber jumper structure

Fiber optic jumpers are similar to coaxial cables, except that there is no mesh shielding. In the center is a glass core through which light travels. In a multimode fiber, the diameter of the core ranges from 15μm to 50μm, which is roughly the thickness of a human hair. The diameter of the single-mode fiber core is 8μm~10μm. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber inside the core. The outer layer is a thin plastic coat to protect the envelope.

Classification of fiber jumpers

Fiber jumper according to different transmission media can be divided into common silicon fiber single mode, multi-mode jumper, and other such as plastic as the transmission media fiber jumper; According to the structure of connecting head, it can be divided into: FC jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper, D4 jumper and so on. Common fiber jumpers can also be classified into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, and SC-ST.
