Product Details
D2x2B Multimode Optical Switches 850nm Dual 2x2 Bypass , Fiber
Optic Switches
The GEZHI Series Dual 2x2 Bypass opto-mechanical fiber optic switch
provides 2 simultaneously activated 2 x 2 Bypass switches in a
single compact package. The device connects optical channels by
redirecting incoming optical signals into selected output fibers
The switch is bidirectional.
The Dual 2x2 Bypass Opto-Mechanical Bi-directional Fiber Optic Switch connects optical channels by redirecting 4 incoming optical signals into 4 output fibers. The switch has integrated electrical position sensors.Based on thin film filter technology that provides a robust method of altering the light patch, this
series of products has a drastically simplified platform
configuration offering high reliability and low production cost.
This novel design significantly reduces moving part position
sensitivity, offering unprecedented high stability as well as an
unmatched low cost.
