Abstract: An optical switch for selectively coupling the free end of an input fiber to the free ends of one of two output fibers. Each of the output fibers is adhesively fixed within a v-groove of an output alignment block. The output alignment blocks are held in stacked relationship within a housing with their v-grooves upturned. An input alignment block having an inverted v-groove within its bottom surface is provided for guiding the input optical fiber, upon switching, toward engagement with the output fiber fixed to the upper output alignment block.

Abstract: An optical switch for selectively coupling the free end of an input fiber to the free ends of one of two output fibers includes a fiber stabilizing guide. Each of the output fibers is adhesively fixed within a v-groove of an output alignment block. The output alignment blocks are held in stacked relationship within a housing with their v-grooves upturned. An input alignment block having an inverted v-groove within its bottom surface is provided for guiding the input optical fiber, upon switching, toward engagement with the output fiber fixed to the upper output alignment block. A generally-planar fiber guide is fixed transverse to the arm of a two-position switch. The guide includes an internal rectangular aperture for receiving the input fiber whose width and height each exceed the diameter of the fiber.
