Product Description

AFL’s Polarization Maintaining (PM) Fiber Assemblies utilize PANDA-style fiber in bare fiber and 900μm buffer fiber configurations combined with FC, SC, or LC terminations.

These keyed connectors allow the use of industry standard adapters while giving you reliable and quality connections for applications where maintaining polarization propagation through the core of the fiber is necessary.

The axis orientation is maintained by using tunable connectors that have a high extinction ratio and low insertion losses. AFL can provide standard PM assemblies as specified below, or create a custom solution to meet the need of your specialty photonics applications.
