<p>T/AB 826 An improved tool is disclosed for use in cleaving fiber optic elements preparatory to a splice for joining of two such fiber optic elements. The improved tool comprises support means having a longitudinal axis for supporting the fiber optic element therealong, grooving means for forming a groove in the surface of the fiber optic element, engagement causing means for causing engagement of the grooving means with the fiber optic element, and mounting means for mounting the grooving means to rotate about the longitudinal axis of the support means to circumferentially groove a fiber optic element about its entire circumference. The grooving means includes a stop surface spaced from the longitudinal axis and a grooving tip that extends a predetermined distance beyond the stop surface. Included in the engagement causing means is an auxiliary support member having a V-shaped notch in a supporting surface facing the grooving means for supporting a portion of the fiber optic element. The V-shaped notch has a depth less than the diameter of the fiber optic element so that when the engagement causing means causes engagement of the fiber optic element with the stop surface, the grooving tip extends a predetermined distance into the fiber optic element.</p> |
