Polarization Maintaining Fiber Patch Cord / PMF Jumper / Polarization Insensitive
Key Specifications/Special Features:
Polarization maintaining (PM) optical patch cords are widely used in polarization sensitive fiber optical systems for transmission of light that requires the PM state to be maintained.
Polarization Maintaining Patch-cord(Polarization Maintaining jumper) 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.
We provide PM patch cords at five different wavelengths (from 980nm to 1550nm).
Those patch cords are made using best-known PM optical fibers and first-class quality optical fiber connectors.
Our PM patch cord features high extinction ratio, low insertion loss, high return loss and long term reliability.
Various PM fiber and connectors are available.
