Description and Application

      Fiber optic patch cords, also known as fiber optic connectors, are devices for removable (movable) connections between optical fibers and optical fibers, which butt the two end faces of the optical fibers together in a precise manner in order to maximize the coupling of the optical energy output from the transmitting fiber into the receiving fiber and minimize the impact on the system due to its intervention in the optical link. Most fiber optic patch cords generally use a high-precision assembly (consisting of two pins and a coupling tube in a total of three parts) to achieve optical fiber alignment connection. In this method, the optical fiber is threaded and fixed in the pins, and the surface of the pins is polished before alignment is achieved in the coupling tube.
