LightBend™ 1×1, 1×2 PM Optical Switch

Enquire Now

The LB series 1×2 PM fiber optic switch has a polarization-maintaining fiber switch, which connects optical channels by directing or blocking an incoming optical signal into the output fiber.  This is achieved using a patent pending opto-machnical configuration and achieved via an electrical control signal.  A latching version preserves the selected optical path after the drive signal has been removed, while the non-latching version defaults to either the open or close state when power is removed.  The switches integrated electrical position sensors.  The new material-based advanced design significantly reduces moving part position sensitivity, offering unprecedented high stability as well as an unmatched low cost. Electronic driver is available for this series of switches. The switch is bidirectional.
