Abstract: A method, apparatus, and conversion kit for curved-angle cleaving of optical fibers, and a curved-angle end-face of a resulting optical fiber. The method requires fixing first and second portions of the optical fiber and introducing a flaw into the optical fiber between the first and second portions. Then, a substantially concentrated force is applied to the optical fiber between the flaw and the first portion of the optical fiber, on a side of the optical fiber opposite the flaw, in order to cause the optical fiber to cleave with a curved-angle cleave. Another embodiment of the method applies a substantially concentrated force to the fiber before introduction of the flaw.

Abstract: A method and apparatus for curved-angle cleaving of optical fibers. The method requires the introduction of a flaw in an optical fiber to be cleaved, and the application of predetermined stress and strain to the optical fiber in the vicinity of the flaw to cause curved-angle cleaving of the optical fiber at the flaw. The apparatus of the present invention includes first and second pairs of optical fiber clamps separated by first predetermined distance, a flaw-producing device that produces a flaw in a fiber clamped between the clamps, and a force-applying device that applies a substantially concentrated force to the fiber at a second predetermined distance from the first pair of clamps, the flaw-producing device being located between the force-applying device and the second pair of optical fiber clamps at third predetermined distance from the force-applying device. The first, second and third predetermined distances are selected in order produce a curved-angle cleave in the optical fiber.
