Fiber Optic Switches

Dovetail translational microstages may also be used to create a fiber optic switch for fiber optic communications. Fibers are mounted on the stages and magnetically actuated to align the input fiber to the appropriate output fiber. Switching speeds of less than 8 msec have been achieved with <-80 dB crosstalk and <-1 dB loss.
