1. A dual 1×
- 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 90°
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.

Abstract
A fiber optics switch has a retro-reflector mirror assembly which reflects a light beam received from an input fiber in an anti-parallel, displaced manner, into one of a plurality of output fibers. Insensitivity to temperature changes, wear and tear, and vibration is achieved as well as very compact size and high speed.
