Mini 1x8 Mechanical Optical Switch
GEZHI Series Mini 1x8 fiber optic switch connects optical channels by redirecting an incoming optical signal into a selected output fiber. This is achieved by using a patent pending opto-mechanical configuration activated via an electrical control signal. The latching operation preserves the selected optical path after the drive signal has been removed.
The switch has integrated electrical position sensors, and the new material-based advanced design significantly reduces moving part position sensitivity, offering unprecedented high stability and an unmatched low cost.
