METHOD OF COATING OPTICAL FIBER AND DEVICE FOR COATING

摘要

PROBLEM TO BE SOLVED: To provide a method of coating an optical fiber capable of increasing the working rate of re-coating the coated area of an optical fiber, and to provide a device for coating. SOLUTION: This method comprises the steps of setting a core fiber 3 of an optical fiber in which a part 4 is removed of the coating to a mold 10, coating the part 4 with a photo-curable resin 7, and while heating the photo- curable resin to its glass transition temperature by a heater 13 under control of a Peltier element 12 and a temperature control device 15, irradiating a light for curing from the light source 2 to cure the photo-curable resin.
