Full 2x2
Fiberoptic Switch
(Protected by U.S. patent 6823102 and pending patents)
Product Description
The LB Series Full 2x2 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.
