As an important component of optical communication systems, the quality of fiber optic jumpers' connectors determines the transmission quality of the network. The function of the connector is to precisely connect the two separated fiber end faces, so that the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. Optical fiber connectors i...
