摘要： Device and method for chemical deposition on an elongated member of vitreous material in which a rotating gripping member causes a first end portion of the elongated member to rotate. The second end portion of the elongated member is borne by a pair of supporting members which are axially spaced apart (L1) and are capable of permitting angular rotational movement and axial sliding of the second end portion. Each supporting member also applies a radial constraint preventing the second end portion from moving away from the axis of rotation, thus forcing the second portion and the elongated member to lie with a longitudinal axis coaxial with the axis of rotation. Any curvature of the elongated member is corrected and recovered in this way.

摘要： A process for producing a low-attenuation optical fiber by producing a soot core preform by chemical deposition on a substrate; removing the substrate from the soot core preform, thereby forming a central hole along the soot preform; drying and consolidating the soot core preform in a consolidation furnace to form a glass core preform; heating the glass preform in the consolidation furnace above a glass melting temperature to produce a reduction of the diameter of the central hole; and stretching the glass core preform to completely close the central hole.
摘要翻译：一种生产低衰减光纤的方法，该方法是通过在基片上进行化学沉积制造烟灰芯预制件; 从烟灰芯预制件移除基材，从而沿着烟炱预制件形成中心孔; 将烟灰芯预制件干燥并固结在固结炉中以形成玻璃纤芯预制件; 将玻璃预制件在固化炉中加热到玻璃熔融温度以上以减小中心孔的直径; 并拉伸玻璃纤维预制件以完全闭合中心孔。
