Mini 1×1 1×2 2x2Bypass Optical Switch

 

Description 

The LB Series miniature fiber optic switch connects optical channels by redirecting incoming optical signals into selected output fibers, in 1×1, 1×2 and 2×2 (bypass) configurations. This is achieved using opto-mechanical configuration and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. The switch has integrated status contacts to provide an electrical readout of switch position. The new material based advanced design significantly reduces moving part position sensitivity, offering unprecedented high stability as well as an unmatched low cost. It is designed for use in reconfigurable OADM, optical cross-connect system and network switching for fault protection applications. Electronic driver is available for this series of switches. The switch is bidirectional.
