METHOD OF MANUFACTURING OPTICAL FIBER AND APPARATUS OF MANUFACTURING OPTICAL FIBER

Title:

METHOD OF MANUFACTURING OPTICAL FIBER AND APPARATUS OF MANUFACTURING OPTICAL FIBER

Document Type and Number:

Japanese Patent JP2023128454

Kind Code:

A

Abstract:

To provide a method of manufacturing an optical fiber which suppresses variation of a coating thickness deviation of an optical fiber, etc.SOLUTION: A method of manufacturing an optical fiber includes the steps of: melting an optical fiber base material and wiredrawing an optical fiber bare wire; coating the optical fiber bare wire with a resin by a coating device to form an optical fiber element wire; and changing a direction of the optical fiber bare wire by a direct down roller and winding the optical fiber bare wire by a winding device. The direct down roller is a non-rotary guide roller.SELECTED DRAWING: Figure 1
