Fiber optic jumpers are used to make jumpers from equipment to fiber optic cabling links. There is a thicker protective layer, which is generally used in the connection between the optical transceiver and the terminal box, and is used in some fields such as optical fiber communication systems, optical fiber access networks, optical fiber data transmission, and local area networks.
The role of fiber optic jumpers

Fiber patch cords generally play a role in that fiber patch cords, in general, are a transmission medium used between equipment and equipment. For example, the signal interface of device A is A1, and the signal interface of device B is B1. Then you need to connect two devices, you need to have an optical fiber, the interface of one section of the optical fiber is A1 head, and the interface of the other section is B1 head, so that the two devices can be connected together. This kind of two ends has an adapter (connector ) Fiber is called a jumper. By the way, an optical fiber with an adapter at one end is called a pigtail
