Abstract
A method for manufacturing an optical fiber includes: gripping a preform by a gripper that includes an aligner; forming a bare fiber by melting the preform in a melting furnace; cooling the bare fiber by blowing gas in a cooler; applying a resin and coating an outer circumference of the bare fiber; curing the resin; acquiring input information that changes a flow rate of the gas blown to the bare fiber in the cooler; and adjusting based on the input information an entry position of the bare fiber into the cooler by controlling the aligner and moving the preform.
