Abstract

PURPOSE:To improve the detects produced as the viscosity of SiO2 - B2O3 becomes lower than that of quartz at the time of spinning and letting refractive index lower as tensile stress acts upon the SiO2 - B2O3 portion after it is made to a fiber by laminating quartz on the outermost layer.
