METHOD FOR MANUFACTURING OPTICAL FIBER

摘要

PROBLEM TO BE SOLVED: To provide a core wire of an optical fiber coping with the high wiredrawing speed of optical fibers without losing transmission property. SOLUTION: When a liquid composition of an electron bean curable resin is coated on a bare wire of the optical fiber and irradiated with an electron beam under almost atmospheric pressure, magnetic field is place on the part for passing the optical fiber so that the irradiation efficiency is improved.
