Product Details
Description of 2x2 Polarization Maintaining (PM) Mechanical Optical
Switch Latching FC/APC
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.
Unifiber’s polarization maintaining (PM) fiber switches are
fabricated from PM panda fibers and high-quality connectors that
are compatible with industry standards.
