ABSTRACT:
Two sets of cylindrical fingers disposed in an interdigital relationship pivoted together, scissors fashion, to receive a portion of an optical fiber cable. When the fingers are rotated to a closed position, they create a predetermined series of bends in the portion of the optical fiber cable that can be observed by an optical time domain reflectometer. This observation allows a remote monitor to determine the relative location of the bends with respect to a suspected break or other anomaly in the optical fiber cable so that a maintenance or repair crew can go directly to the location of the anomaly for quick action.
