OptoMechanical Fiberoptic Switch
(Protected by U.S. patent 6823102 and pending patents)
Product Description
The LB Series miniature fiber optic switch connects optical channels by
redirecting incoming optical signals into selected output fibers, in 1x1, 1x2
and 2x2 (bypass) configurations. 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 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.
