Polarization Maintaining Optical Switch (PM Fiber Switches) is a passive component possessing two or more ports that selectively transmits, redirects or blocks optical signals from a given input port to a given output port in an optical fiber transmission line. OPTEKCOM’s polarization maintaining (PM) fiber switches are fabricated from PM panda fibers and high-quality connectors that are compatible with industry standards. They are able to maintain a well-defined state of polarization (SOP) of the light.
