PM fiber coupler is used for splitting optical signals in polarization maintaining panda fiber, it is a micro optic filter type device that provides optical signal splitting while preserving polarization with high ER. this coupler is available in a wide range of coupling ratio's from 1% to 50%, normally come as 1x2 and 2x2 for options. PM couplers are widely used in fiber optic communication systems, Raman Amplifiers and other fiber instrument applications.
