Abstract: A glass preform for optical fibers is produced using two burners, one for forming the preform core, producing a stream of glass raw material consisting of SiCl4 and the other for forming the preform cladding and producing a stream of second raw material consisting of a cpd. or cpds. from the gp. SiHCl3, SiH2Cl2, SiH3C1 and SiH4. The glass raw material is hydrolysed by the flame to synthesise fine glass particles, which are deposited on to a starting member having a longitudinal axis. The shoot preform so produced is then heated and sintered to obtain a transparent glass preform. Shoot particles are deposited and grown in a direction parallel to the axis of the starting member.
Abstract translation: 使用两个燃烧器制造用于光纤的玻璃预制件，一个用于形成预制棒芯，产生由SiCl 4组成的玻璃原料流，另一个用于形成预制件包层并产生由cpd组成的第二原料流。 或cpds。 从gp。 SiHCl 3，SiH 2 Cl 2，SiH 3 Cl和SiH 4。 玻璃原料被火焰水解，合成细微的玻璃颗粒，其沉积在具有纵向轴线的起始构件上。 然后将如此制备的枝条预制件加热并烧结以获得透明玻璃预制件。 拍摄颗粒在平行于起始构件的轴线的方向上沉积并生长。
