The optical fiber jumper (also called optical fiber connector) means that connector plugs are arranged at two ends of an optical cable and are used for realizing movable connection of an optical path; one end of the optical fiber is provided with a plug, and the optical fiber is called a tail fiber. Optical Fiber Patch cords (Optical Fiber Patch Cord/Cable) are similar to coaxial Cable, except that there is no mesh shielding. The center is the glass core through which the light propagates. In the multimode optical fiber, the core diameter is 50 to 65 μm, and approximately corresponds to the thickness of human hair. And the diameter of the single-mode optical fiber core is 8-10 μm. The core is surrounded by a glass envelope having a lower refractive index than the core to retain the optical fiber within the core. Further on the outside is a thin plastic outer sleeve to protect the envelope.
The optical fiber patch cord can be divided into common single-mode and multi-mode patch cords of silicon-based optical fibers according to different transmission media, and other optical fiber patch cords taking plastic and the like as transmission media; according to the connector structural style can be divided into: FC jumpers, SC jumpers, ST jumpers, LC jumpers, MTRJ jumpers, MPO jumpers, MU jumpers, SMA jumpers, FDDI jumpers, E2000 jumpers, DIN4 jumpers, D4 jumpers, and the like.
