The LB Dual 2×2 Bypass OptoMechanical Fiberoptic switch is an integrated single device with 8 fiber ports. Based on Photonwares’s patented technologies, the switch is designed especially for protection and restoration applications. The switch is activated by a low voltage pulse between two states, and the latching operation preserves the selected optical path after the drive signal has been removed. The switch has integrated electrical contact based status sensors. The design significantly reduces moving part position sensitivity, offering unprecedented high stability as well as an unmatched low cost. Electronic driver and circuit design assistance are available for this series of switches. The switch is bidirectional.

We offer tight-bend-fiber version, which reduces the minimum bending radius from normal 15 mm to 7 mm. This feature enables smaller overall foot print.
