Frequently Asked Questions

A Polarization Maintaining (PM) Patch Cord is a fiber optic cable designed to maintain the polarization of light as it travels through the cable, using PM panda fiber and connectorized with FC/UPC or FC/APC connectors.

The PM Patch Cord is available with FC/UPC, SC/UPC, FC/APC, and SC/APC connector types.

The key features include high extinction ratio, low insertion loss, default key alignment to the slow axis, and availability in various jacket cable diameters (250um, 900µm, 2.0mm, and 3.0mm).

The PM Patch Cord is used in switching, EDFAs, coherent optical communications, integrated optics, high-speed transmission devices, external modulators, and interferometric sensors.

The PM Patch Cord can handle a maximum optical power of 300mw.

The operating temperature range for the PM Patch Cord is -20 to +70°C.

When ordering, you can specify the fiber length (ranging from 0.5m to 20m) and the fiber type (3.0mm, 2.0mm, 900um, or 250um) using the provided ordering information code format.
