ABSTRACT:
A method of cleaving an optical fiber and apparatus therefor including a hand tool wherein the optical fiber to be cleaved (6) has a natural path. The method of cleaving includes deflecting the optical fiber (6) away from its natural path in a first direction and at a point spaced longitudinal along the length of the fiber deflecting the optical fiber in a second direction opposed to the first direction. The opposing deflection induce internal stresses in the fiber that extend substantially across the core of the optical fiber over a region of the length of the optical fiber. The fiber may then be scratched in this region with a cleaving blade (5) so as to induce cleaving of the optical fiber. The cleaving is controlled by controlling the internal stresses induced in the fiber by in turn controlling the degree of deflection induced in the fiber. Further the fiber (6) may be placed under extension to assist in the control of the stresses induced.
