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...

In optical communication systems, optical modules are the core of optical signal transmission, and their performance is crucial to network stability and reliability. However, when long-distance optical modules are directly connected to short-distance optical fibers without attenuation, the optical components at the receiving end are easily damaged. This involves complex optical power management an...
