LightBend™ 1×4 PM High Power Optical Switch

Enquire Now


The LB 1×4 Series fiber optic switch connects optical channels by redirecting an incoming optical signal into a selected output fiber. This is achieved by using a patent pending opto-mechanical configuration activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. The switch has integrated electrical position sensors, and 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.
