PM Filter Coupler Module ( 1x4 / 1x8 ): 1310nm/1550nm Polarization maintaining coupler modules combine multiple incoming optical fiber inputs into one output, while maintaining the polarization state of the light. It can aslo be used as a PM splitter. Our PM coupler modules are assembled using thin-film filter-based 1x2 and 2x2 PM optical fiber couplers, with center wavelengths at 1310nm or 1550nm or 1064nm, and bandwidth of +/-30nm.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. DK Photonics offers a large selection of PM Filter Coupler Module. These devices can handle powers rang from 300mW to 2W or other on request, available in 1xN and 2xN(N<10) types, and have center operating wavelengths ranging from 980 nm to 1650nm. If you do not see a standard PM Filter Coupler Module that meets your needs, we welcome the opportunity to review your desired specification and quote a custom PM Filter Coupler Module. Requests for custom fiber pigtails,differebt,coupling ratio different wavelengths and handling power of operation or other specific needs will be readily addressed.
