The LB series 1×1, 1×2 High Power OptoMechanical fiber optic switch can be configured as either a 1×1 switch or a 1×2 switch. Based on Photonwares’s patent pending, it can work in high optical power up to 10 W. The switch is driven by a pulsed electrical signal, and the latching operation preserves the selected optical path after the drive signal has been removed. Its integrated status contacts to provide an electrical readout of the switch position. It is designed for high optical power and some specific applications. Electronic driver is available for this series of switches. The switch is bidirectional.
