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.
