Optical fiber patch cord / jumper, also known as (optical fiber connector), is a detachable (movable) connection device between optical fiber and optical fiber. It connects the two ends of the optical fiber to face each other so that the optical energy output by the optical fiber can be coupled to the receiving fiber to the maximum To minimize the impact on the system due to its involvement in the optical link. Optical fiber jumper (optical fiber connector) is divided into: multi-mode 62.5 / 125, multi-mode 50/125, single-mode 9/125, multi-mode 10G 50/125
