Optical fiber cutting apparatus and optical fiber cutting method therefor

摘要

An optical fiber cutting apparatus comprises a coated section holder (21), an uncoated section holder (22), and a cutter (24). A ferromagnetic substance or a magnet is disposed on a surface of the uncoated section holder (22) and a surface of the cutter holder (25) which are facing each other. A ferromagnetic substance or a plurality of magnet having different magnetic force are disposed with equal interval on the uncoated section holder (22) or the cutter holder (25). Tension is applied to the optical fiber (1) by repulsing-force which exists among a magnet (33), a first magnet (35), and the second magnet (36). Tension which is applied to the optical fiber increases gradually. By doing this, an optical fiber cutting apparatus is provided which does not decrease strength of the optical fiber.
