Abstract

PURPOSE:To provide the title fiber free from alkali elution, having superior weather resistance, superior dimensional stability, an improved endurance life and an improved loss, and consisting of core glass contg. SiO2, Al2O3, alkali metal oxide and B2O3 and of clad glass contg. SiO2, Al2O3, alkali metal oxide and B2O3. CONSTITUTION:The fiber is formed with multicomponent system core glass consisting of, by wt., SiO2 50-70%, (GeO2 may be substd. for 30% or less of the SiO2), Al2O3 0.5-7%, alkali metal oxide 10-23%, CaO 0-10%, B2O3 4-15% and MgO 0-5% and multicomponent system clad glass consisting of, by wt., SiO2 60- 80%, Al2O3 0.5-10%, alkali metal oxide 9-17%, CaO 0-5%, one or more out of ZnO, ZrO2 and TiO2 0-7%, MgO 0-4% and B2O3 10-15%.
