Polarization Maintaining Fiber Patchcords |
-
Polarization Maintaining (PM) patchcords are based on a high precision butt-style connection technique.
-
The PM axis orientation is maintained by using male connectors with a positioning key and a bulkhead female receptacle with a tightly toleranced keyway, ensuring good repeatability in extinction ratios and insertion losses.
-
The polarization axis of a fiber is aligned with the connector key by rotating either the connector frame or the fiber itself until the polarization axis is in line with keyway of the connector.
-
Once the fiber is correctly aligned, the alignment can be fixed with a drop of glue or epoxy.
-
OZ Optics minimizes backlash and rotational errors in the PM axis alignment by using specially designed PM ferrules and connector housings.
