Dual 1x1
MultiMode Fiberoptic Switch
(Protected by U.S. patent 6823102 and pending patents)
Product Description
The LB Series Dual 1x1 multimode OptoMechanical Fiberoptic switch
connects optical channels by redirecting incoming optical signals into
selected output fibers. This is achieved using a patent pending 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 electrical position sensors. This
novel 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.
