摘要： PROBLEM TO BE SOLVED: To provide an optical fiber having a specific highly accurately stable optical characteristic by reflecting the measured data of the wiredrawn optical fiber to the later wiredrawing.
SOLUTION: In this manufacturing method of an optical fiber, when an optical fiber manufactured by a temporary wiredrawing did not attain the target value of the specified optical characteristic, a temporary outer diameter resetting process is carried out to reset the temporary outer diameter. This temporary outer diameter resetting process comprises a theoretical value calculation process in which a specified theoretical value of the optical characteristic of the optical fiber obtained by wiredrawing a preform is calculated based on the distribution of refractive index and the temporary outer diameter of the optical fiver, an empirical correction value calculation process in which an empirical correction value is calculated to correct the theoretical value by comparing the specific optical characteristic of the optical fibers manufactured before and the specific optical characteristic obtained in the actual measuring process, and a temporary wiredrawing outer diameter decision process in which a wiredrawing outer diameter is set as a temporary outer diameter so that the value obtained by multiplying the theoretical calculated value with the empirical correction value will be the target value.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for drawing an optical fiber, by which gas seal drawing can be performed stably. SOLUTION: When the optical fiber 40b is manufactured by blowing a gas 15 to an optical fiber preform 30, at the same time, sealing the inside of a drawing furnace 20 by seal rings 14U, 14L provided at the upper part and the lower part of the drawing furnace 20, respectively, and heating and melting the tip end part of the optical fiber preform 30 while introducing the optical fiber preform 30 into the drawing furnace 20, the gas 15 is blown while changing the inner diameter of the upper seal ring 14U according to the outer diameter of the optical fiber preform 30 fed into the drawing furnace 20. Thereby, it is possible to stably perform drawing because the gap between the optical fiber preform 30 and the upper seal ring 14U can be kept constant even when the outer diameter of the optical fiber preform 30 changes.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical fiber by which it is possible to easily shift to normal drawing in a short time and the yield is improved. SOLUTION: The method for manufacturing an optical fiber G2 includes covering a glass fiber G1, obtained by softening an optical fiber preform G by heating it and drawing the resulting preform G, with a resin, and taking-up the covered glass fiber.
