ABSTRACT:
A method of breaking optical fibers, a fiber being scored over the entire circumference in a plane perpendicular to the fiber axis. By subsequently applying a predetermined axial tensile force to the fiber, fracture is initiated over the entire circumference of the fiber. As a result of this, fibers with a comparatively large diameter can be broken in such a way that a mirror zone is obtained across the entire fracture area. Circumferential scoring also ensures the required accuracy in respect of the perpendicular orientation of the fracture plane relative to the fiber axis.
