ABSTRACT:
Optical fibers are cleaved with high precision by a technique that yields flat endfaces that are perpendicular to the axis of the fiber within 1 degree, and typically within 0.5 degree. This is very advantageous for obtaining low loss splices of fibers, especially single mode fibers. In the present technique, a fiber is secured in two linearly aligned chucks in a sequence that allows one end to rotate unconstrained to minimize tortion. An axial tension is then applied in the fiber, which is next scored. The fiber then typically breaks, but cleaving can be promoted by applying further tension, or introducing moisture, if necessary.
