ABSTRACT:
An M.times.N mechanical optical switch has opposing input and output optical fiber bundles disposed within offset ferrules. Each ferrule is mounted in three-point kinematically correct V-groove holder allowing the optical fibers in each optical fiber bundle to traverse on a closed curve path during the rotation of the respective ferrules. The closed curve paths of each optical fiber in one of the optical fiber bundles intersect at least one of the closed curve paths of the optical fiber in the opposing optical fiber bundles. The intersection points of two opposing closed curve paths establish the optimum positioning locations for two opposing fibers. Offsetting the axes of rotation of the opposing optical fiber bundles and mounting the bundles in a three-point kinematically correct holder produces a mechanical optical switch having superior cycle-to-cycle repeatability, long term repeatability, and absolute alignment using loosely toleranced components.
