1M FC/APC PM Patch Cords 1550nm Polarization Maintaining PMF Patch Cord

Polarization maintaining (PM) patch cord / jumper leads are built with polarization maintaining panda fiber and connectorise using FC/UPC, FC/APC, SC and LC connectors. Patchcords can be supplied in 250um bare fiber, 900um buffered fiber or 3mm cable.

Angnet's PM fiber assemblies that are able to precisely aligned to either the mechanical plane (with respect to the stress rods), or to the optical plane (active alignment with respect to the launched optical signal). All assemblies are tested for Insertion Loss, Return Loss and Extinction Ratio to ensure the highest quality assemblies are supplied.

The unique feature of PMF terminations is that the fibers must be accurately aligned with respect to the connector key. The alignment ensures that when two PM fibers are mated in an adapter, or when a PM assembly is connected to a polarized source, the optical polarization planes are in close alignment to minimize optical losses. Alignment is typically performed to the slow axis, however other orientations are achievable.

Angnet utilizes the Panda PM fiber construction, available in 1300nm and 1550nm wavelengths as a standard, other fiber types and wavelengths can be supplied. Assemblies are also available with either a standard PC type polish or an 8° angled polish for lower Return Loss requirements.
