Abstract:
A dual 1Ã—2 reflector switch comprising:(a) two first beam-forming units and two second beam-forming units disposed in a square about a rotation axis, each beam-forming unit comprising an optical fiber and a lens secured thereto, with said two first beam-forming units diagonally disposed about said rotation axis; (b) two rotatable reflector assemblies, in parallel, disposed symmetrically about said rotation axis, arranged such that an optical signal from each first beam-forming unit is reflected into each one of said second beam-forming units, respectively, forming a first set of second beam-forming units and, upon 90Â° rotation of said two rotatable reflector assemblies, said optical signal from each first beam-forming unit is reflected into each other of said second beam-forming units, respectively, forming a second set of second beam-forming units; and (c) a mechanism for rotating said two rotatable reflector assemblies to alternately align said optical signal between said first set of second beam-forming units and said second set of beam-forming units.
