摘要： A method of manufacturing an optical fiber, comprises applying a UV cured resin to an outer circumference of a running glass optical fiber, forming an accompanying flow composed of an inert gas near a surface of the resin by passing the glass optical fiber immediately after having the resin being applied through an atmosphere of the inert gas, and forming a coating by irradiating the resin coated with the accompanying flow with ultraviolet ray to cure the resin while the glass optical fiber accompanied by the accompanying flow is passed through a UV transmission tube to which a gas containing oxygen is supplied.

摘要： The present invention provides an optical fiber superior in yellowing resistance. An optical fiber according to the present invention has a coating made from a UV curable resin formed on the outer surface of a bare optical glass fiber, and is characterized in that the coated material includes an unreacted photoinitiator in an amount of 2.4×10−3 mole equivalent or less in 1 g of the material. The optical fiber is characterized in that the UV curable resin includes urethane acrylate, a polyisocyanate component in the urethane acrylate is an aromatic polyisocyanate, and tolylene diisocyanate is used as the aromatic polyisocyanate.
