PURPOSE:To cut an optical fiber so that end surfaces are specular and smooth by supporting the optical fiber in a cantilever state, applying a tensile or pressing force to a position close to a tip side than a position where a cut flaw is made, and cutting the optical fiber at the cut flaw position. CONSTITUTION:A cutter 10 while rotated is brought into contact with the optical fiber 2 supported in a ferrule 1 and the cut flaw is made in a conic recessed part 9 at the tip 8 of the ferrule 1. Then, the pressing force shown by an arrow H is applied to a pressing member 11 provided on the side closer to the tip than the cut flaw to press the pressing member 11 against a cantilever receiving piece 42 which is curved elastically and fixed to the holding bush 28 of the ferrule 1. While the optical fiber 2 is clamped with uniform pressure by the clamping and drawing mechanism 20 consisting of the pressing member 11 and receiving piece 42, a bending and the tensile force (or pressing force) are applied to the tip side of the optical fiber 2, which is cut at the position of the cut flaw. |
