Abstract
An optical signal channel selection device which includes a plurality of first fixed optical signal channels for transmitting optical signals along a plurality of first parallel optical axes and a second fixed optical signal channel for transmitting optical signals along a second optical channel axis parallel to the first axes. A pair of reflective surfaces are fixed so as to be parallel to each other, the reflective surfaces being movable between the first optical channels and the second optical channel so that a first one of the reflective surfaces can be selectively positioned opposite selected ones of the first signal channels and the second reflective surface is positioned opposite the second signal channel. An input optical signal from a selected one of the first channels is incident on the first reflective surface and is directed toward the second reflective surfaces so as to be reflected therefrom in parallel with the input optical signal.
