PURPOSE:To obtain a smooth inclined end surface by applying flaws at a position where bending stress of an optical fiber was produced. CONSTITUTION:By supporting an optical fiber 1 with a pair of clamps 2a, 2b, tensile stress and torque are given, and by bending the central part along a convex surface of a jig 3, at this part bending stress is produced. When with this state a maximum part of bending stress is pressurized with a diamond cutter 4, etc., and the part is scraped, stress rupture is produced and a smooth inclined end surface is obtained. An inclination angle at the inclined end surface changes with torque and bending stress. If torque is not applied, an end surface perpendicular to the center of the optical fiber 1 is obtained. |
