PM Patch Cables

PM Patch Cables (Polarization Maintaining Patch Cords) are connecting devices used in optical systems to connect input and output ports between optical devices. Unlike ordinary fiber optic patch cables, PM Patch Cables have the additional feature of being able to maintain the polarization state of optical signals.

In fiber optic communication systems, optical signals usually have a specific polarization state, such as linear or circular polarization, and PM Patch Cables are able to transmit optical signals between the connecting devices while keeping their polarization state unchanged, ensuring the quality and stability of the transmitted optical signals.
