Polarization maintaining splitter/coupler modules combine multiple incoming optical fiber inputs into one output, while maintaining the polarization state of the light. It can also be used as a PM splitter. Our PM coupler modules are assembled using thin-film filter-based 1x2 and 2x2 PM optical fiber couplers.The Polarization Maintaining Coupler is available in a wide range of coupling ratio.

Our PM coupler modules are assembled using thin-film filter-based 1x2 and 2x2 PM optical fiber couplers.The Polarization Maintaining Coupler is available in a wide range of coupling ratio. PM couplers are widely used in fiber optic communication systems, Raman Amplifiers and other fiber instrument applications.
If you do not see a standard PM fiber Coupler Module that meets your needs, we welcome the opportunity to review your desired specification and quote a custom PM Fiber Coupler Module. Requests for custom fiber pigtails, different coupling ratio different wavelengths and handling power of operation or other specific needs will be readily addressed.
