What is Polarization-Maintaining (PM) optical fiber? The polarization of the light propagating in the regular single-mode fiber, however, gradually changes in an uncontrolled manner, depending on external perturbations such as temperature change and fiber movement. This problem can be solved by using a special fiber called PM fiber. PM fiber is constructed in the way
