XH-OSW-1X4-PM is a polarization-maintaining optical path switching, conversion, and routing device that can switch one input or output end to select one of the multi-channel optical paths for output or input. In fiber optic transmission systems, optical switches are used for conversion of multiple monitors, LANs, multiple light sources, detectors and protected Ethernet. Optical switches are mainly used in: multi-channel optical monitoring in optical transmission systems, LAN multi-light source/detector automatic switching, and optical sensing multi-point dynamic monitoring systems; used in optical testing systems for optical fibers, optical devices, networks and field engineering Optical cable testing; optical device assembly and adjustment.
