Ultra-Mini 1x1, 1x2, 2x2(Bypass)
Fiberoptic Switch
(Protected by U.S. patent 6823102 and pending patents)
Product Description
The LB Series Ultra-mini 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 patented 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.
