ABSTRACT:
A molding die1is constituted by an upper die1aand a lower die1bwhich are made of a material transparent to an ultraviolet light, and has a cavity3constituted by grooves2c, 2d, whereas a resin injection gate4and a resin exit gate7are provided so as to communicate with the cavity3. A junction of an optical fiber10is inserted into the cavity3. A UV-curable resin is injected into the cavity3surrounding an exposing portion of the glass optical fiber11from the resin injection gate4positioned at one of coating ends of the optical fiber10, whereas a part thereof is discharged from the resin exit gate7positioned at the other coating end. The ultraviolet light is emitted through the lower die1bso as to cure the resin, thereby forming a reinforcement resin coating. As a consequence, bubbles can be prevented from occurring due to the residual air within the reinforcement resin coating in the junction of the optical fiber10.
