Optical Switches
LightBend™ High Power 3x3, 4x4 Optical Switch
LBPM, LBHP, LBPH The LightBend 4×4 Series fiber optic switch connects optical channels by redirecting any of four incoming optical signals into any of four output fibers. This is achieved using a patent-pending opto-mechanical configuration and is activated via an electrical control signal. The latching operation preserves the selected optical path after the drive signal has been removed. This new material-based, advanced design significantly reduces the sensitivity of moving part position, offering unprecedented high stability as well as an unmatched low cost. The LB 4×4 series Switch can be made of a variety of fibers, including SM, MM, and PM fibers, in standard or high-power versions. An electronic driver is available for this series of switches. The LightBend 4×4 series switch is bidirectional.
