Patent EP-0637763-A1.EP-0637763-A1https://hdl.handle.net/2144/36520In accordance with the invention, apparatus for cleaving optical fiber utilizes a pair of displaceable clamping surfaces to rotate the fiber about its axis before the cleaving step. Specifically, the apparatus comprises first holding means for securing the fiber against rotation at a first longitudinal position, a pair of displaceable clamping surfaces for clamping the fiber at a second position, and means for relatively displacing the surfaces to rotate the fiber. Cleaving means applied to the fiber between the first and second position effects cleavage with a tilted endface substantially free of subsurface damage and contaminants. A significant advantage of this apparatus is that it can angle cleave a single fiber or simultaneously cleave a plurality of fibers in a multi-fiber ribbon.Patent429730
