Mini Size 1x8 Opto-Mechanical Optical Switches 8x1 Latching Fiber optic Switch
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. 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 as well as an unmatched low cost.
Features Application
Unmatched Low Cost Channel Blocking
Low Optical Distortions Configurable Add/Drop
High Isolation System Monitoring
High Reliability Instrumentation
Epoxy-Free Optical Path
