Abstract

An optical crossbar switch comprising: a first plurality of first optic fibers having optical ends, each one of which optical ends is mounted to a different first moveable element; a second plurality of second optic fibers having optical ends, each one of which optical ends is mounted to a different second moveable element and at least one motor controllable to translate each first moveable element and each second moveable element so as to align the optical end of any first fiber and the optical end of any second fiber adjacent to and facing each other.
