Abstract
Particular apparatuses implement a method of breaking a rod of brittle material, such as a glass optical fiber, so as to yield a mirrorlike surface across the entire rod end. A decreasing tensile stress is achieved across the cross section of the rod, which at all points is greater than zero but less than the threshold stress at which a mist zone forms, by simultaneously applying longitudinal tension to the rod and bending it in a tool that laterally moves a section of the fiber while holding sections to either side in friction-type clamps. A convenient hand tool for breaking optical fibers uses pivoting clamps which serve to increase tensile stress as bending is increased. Scoring is done before or after the above-mentioned tool operations.
