Abstract
An remote fiber test system includes at least one mechanical optical switch has opposing input and output optical fiber bundles disposed within offset ferrules with at least one input fiber coupled to a measurement test instrument and each of the output fiber coupled to an optical fiber link via wavelength division multiplexers. Each ferrule of the optical switch 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.
