High Power Polarization Insensitive Optical Isolator(1W-5W)
The purpose of the polarization-maintaining device is to maintain the original polarization state of the polarized light or to transform the polarization state as far as possible when connecting or coupling the polarized light in two polarization-maintaining fibers.
There are many PM devices, such as PM connector, PM collimator,Polarization combiner /splitter, In-line Polarizer, PM circulator, PM isolator, PM optical coupler and so on.
