2×2 PM Optical Switch

The Polarisation-Maintaining (PM) 2×2 Optical Switch is an optical device capable of dynamically switching the optical path between two input ports and two output ports while strictly maintaining the polarisation of the optical signal (e.g. linearly polarised TE/TM mode). Its core function is to enable two-channel polarisation-maintaining optical path switching, which is suitable for polarisation-sensitive high-precision optical systems.

Product Description

  The Full 2x2 PM fiber optic switch connects optical channels by directing or blocking an incoming optical signal into the output fiber. This is achieved using a patent pen-ding op to-mechanical configuration and activated via an electrical control signal. A latching version preserves the selected optical path after the drive signal has been removed, while the non-latching versions default to either the open or closed state when power is removed. The switch has integrated electrical position sensors. The new material based advanced design significantly reduces moving part position sensitivity, offering unprecedented high stability as well as unmatched low cost.
