Abstract

PURPOSE:To eliminate the twist of optical fiber and to improve the transmitting performance and reliability by detecting the twist angle of optical fiber drawn down from a drawing furnace and providing the means rotating the optical fiber to the direction reverse to the twisted direction by the same angle as the twisted angle. CONSTITUTION:A perform 12 supported with chuck 2 is sent into the drawing furnace 1 in which fiber-drawing is carried out, and the optical fiber is drawn down. The optical fiber 13 is passed through between a pair of polarizing plates 9 of detecting part 7 under the drawing furnace 1 while strain patterns stored in the optical fiber 13 are projected by a light source 8 and polarizing plates 9 to be caught by a camera 10. These patterns are momently transmitted from the camera 10 to a control part 11 to obtain changing rate concerning time, and the twisted angle theta of the optical fiber 13 is detected thereby. The control part 11 rotates a motor 3 to the direction reverse to the twisted direction by the angle theta, and the perform 12 is rotated by the angle theta through the chuck 2 with the result that the twist of optical fiber 13 is eliminated.
