Abstract

PURPOSE:To obtain an optical fiber with superior strength and watertightness while the loss of light transmission is small, by making a laminated preform, constituting core, clad and jacket parts, with SiO2 glass including specific components, and then fusing and spinning it. CONSTITUTION:The preform is used which has three laminated layers of glass SiO2 glass containing one among GeO2, As2O3, Sb2O5, SnO2, and TiO2 for the part of core 11, that containing one among F, F and B2O3, and F and P2O5 for the part of clad 12, and that containing >=1 among SiO2 or Al2O3, TiO2, ZrO2, and HfO2 for the part of jacket 13. Then, this preform is melted and spinned to obtain a low transmission loss reducing Rayleigh diffusion loss of core 11, and then jacket 13 has a smooth surface because it is soft at a spinning temperature. As a result, compressive strain is left, so that the surface of high strength and excellent watertightness can be obtained.
