1. An optical switch comprising:

  • an input assembly comprising an input optical fiber and a collimating lens in an optical path of an optical signal from the input fiber to radially expand the signal;

    a first output assembly comprising a collimating lens and a first output optical fiber, the collimating lens disposed in the optical path of the optical signal from the input assembly, the first output fiber disposed in the optical path from the collimating lens;

    a second output assembly comprising a second output optical fiber and a collimating lens; and

    a first prism movable between a first position and a second position, the first prism in the first position disposed in the optical path of the expanded signal between the input assembly and the first output assembly so as to redirect the signal through the collimating lens of the second output assembly and into the second output fiber, the first prism in the second position disposed out of the optical path from the input assembly.
