    Abstract: A optical-fiber preform is produced by the stages of: inserting a quartz glass rod (3) as core in a tube (2) as cladding material, injecting via an inlet line (5) a gaseous mixt. of Si halide, F- contg. cpd. and O2 gas (where Si:F ratio is more than 1/300 and less than 1/5), heating the composite to 1000-1600 deg.C with rotating, replacing the atmos. with a gaseous mixt. of halogen-contg. cpd. and O2, reheating and fusing the core and cladding together at not less than 1900 deg.C.

    Abstract translation: 通过以下步骤制造光纤预制棒:将石英玻璃棒(3)作为芯体插入管(2)作为包覆材料,经由入口管线(5)注入气态混合物。 的卤化硅,F- CPD。 和O2气体(Si:F比大于1/300且小于1/5),旋转时将复合体加热至1000-1600℃,取代大气压。 与气体混合。 的卤素 CPD。 和O2,不低于1900摄氏度,将芯体和包层再熔合并熔合在一起。
