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.
