Background

Optical fiber jumpers are used to patch wires from equipment to fiber optic cabling links. There is a relatively thick protective layer that is typically used for the connection between the optical transmitter and receiver and the termination box. 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 jumpers are similar to coaxial cables except that there is no mesh shielding. The center is the glass core where the light propagates. The outer surface of 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.
