Mini 1×8 Opto-Mechanical Optical Switches
Description
GEZHI Series Mini 1×8 fiber optic switch connects optical channels by redirecting an incoming optical Signal into a selected output fiber. This is achieved by using a patented opto-mechanical configuration activated via an electrical control signal. 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 longevity, as well as an unmatched low cost. Electrical driver is also available. The switch is bidirectional. We offer tight-bend-fiber version, which reduces the minimum bending radius from normal 15 mm to 7mm. This feature enables smaller overall foot print.
