PM Fiber Patchcords
Description
Polarization-maintaining (PM) fiber has been developed to maintain the state of polarization of light as it travels through the fiber. This is done with stress applying members within the fiber that create the birefringence. The birefringence defines two orthogonal optical axes, slow and fast axis, through the core where the light travels. Proper alignment to the source and alignment of the fiber within the connector to the connector key is required to maintain this polarization throughout the light path.
