OptoMechanical Fiberoptic Switch
(Protected by U.S. patent 6823102 and pending patents)
Product Description
The LB series 1x2 PM fiber optic switch has a polarization-maintaining fiber switch,
which connects optical channels by directing or blocking an incoming optical signal
into the output fiber. This is achieved using a patent pending opto-machnical
configuration and achieved via an electrical control signal. A latching version
preserves the selected optical path after the drive signal has been removed, while the
non-latching version defaults to either the open or close state when power is removed.
The switches integrated electrical position sensors. The new material-based advanced
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.
