Abstract : An optical switch affords the selective coupling of any of a plurality of input light signals to any of a plurality of optical output paths. A first plurality of ports circumferentially disposed in a first common plane supports means for transmitting and/or receiving optical signals. A second plurality of ports similarly circumferentially disposed in a second common plane having the same central axis as the first common plane, supports means for transmitting and/or receiving optical signals. A rotatable assembly is mounted on a common support structure with the input and output ports and has first and second members which are independently movable about the central axis. A length of flexible fiber optic bundle has one end supported by a radial arm of the first rotatable member of alignment with a selected one of the first plurality of ports and the other end of the flexible fiber optic bundle is supported by a radial arm of the second rotatable member for alignment with any one of the second plurality of ports. The input and output ports are adapted to receive the terminal end of fiber optic cables, electro-optic transducers, or photo-responsive transducers as desired. (Author)
