ABSTRACT:
The present invention provides an apparatus (74 and 200) for switching an optical signal from an input optical fiber (210) to one of a plurality of output optical fibers (214 and 216). The apparatus (74 and 200) includes a collimator (76) for collimating an input optical signal into a collimated beam (216) at an angle with respect to a reference and a decollimator (78) for focusing the collimated beam to an output optical signal (220). The present invention also includes a reflector (92, 208, 218, and 222) for reflecting the collimated beam. The reflector (92 and 208) has a plurality of positions for changing the angle of the collimated beam (216) with respect to the reference so that the output optical signal (220) is focused on one of the plurality of output optical fibers (214 and 216).
