Fiber Optical Device:Polarization Maintaining Jumper

 

Polarization jumpers have orthogonal “slow” and “fast” axes with different propagation constants. There is little coupling between the polarization modes, therefore, light launched on one axis would propagate on that axis. It features high extinction ratio as a result of very accurate active alignment between PM Major axis and the connector key. Various PM fiber and connectors are available.
