GLSUN's polarization-maintaining (PM) 1xN magneto-optical switch is a type of optical switch that combines magneto-optic effects with polarization-maintaining fiber technology to route light signals across multiple output channels while preserving the polarization state. This kind of switch is typically used in applications requiring both stable polarization and precise optical path control, particularly in high-speed telecommunications, quantum communications, and fiber sensing.
