Polarization Maintaining PM Filter Coupler 
The polarization maintaining coupler is a micro optic filter type device that provides optical signal splitting while preserving polarization with high ER.  The polarization Maintaining Coupler is available in a wide range of coupling ratio's from 1% to 50%, and is also available in 1x2 and 2x2 types.  PM couplers are widely used in fiber optic communication systems, Raman Amplifiers and other fiber instrument applications.
