ABSTRACT:
A method and apparatus for imparting an angle cleave to a plurality of optical fibers. The cleaving device comprises a base having a support surface, the support surface having two lower pads which are aligned with two upper pads on a hinged cover, so that the fibers may be clamped between the respective pairs of lower and upper pads. One of the upper pads is designed to shift with respect to its corresponding lower pad; when a fiber is clamped between these pads and the upper pad moves, the fibers twist as a result of the induced torsional load. When the fibers are scored and cleaved while in the twisted state, the resulting end faces are at an oblique angle with respect to the fiber axes, which is beneficial since this reduces signal reflections at the fiber-to-fiber interfaces.
