Polarization-Maintaining Fiber Patch Cable

Polarization-Maintaining Fiber Patch Cable

Supplier

Category
Fiber Cables & Bundles
Origin
China

Compared with conventional fiber patch cords, polarization-maintaining patch cords use more precise connectors and adapters for alignment to preserve the orientation of the polarization-maintaining optical axis. Their connectors and adapters have smaller deviations, and the adapter keyways that engage the connector keys are narrower than conventional ones. This ensures good extinction-ratio repeatability and low insertion loss.
