ABSTRACT:
A low profile optical switching device has a housing with a width and length considerably greater than its height, a motor having an upright shaft extending less than the height of the housing, a circular faceplate surrounding an upper end portion of the shaft and having a diameter considerably larger than the length of the shaft, and a plurality of first optical fibers each having a fixed fiber end portion held by the faceplate. The fixed fiber end portions, usually constituted by lenses, are arranged so as to define a substantially cylindrical imaginary surface co-axial with and communicating with the faceplate. These fixed fiber end portions can receive light from a further optical fiber having a movable end portion carried by an arm extending radially from the motor shaft and which moves around a circular path adjacent the fixed fiber end portions, the light being transmitted via a prism mounted on the arm adjacent the movable fiber end portion.
