摘要
低水峰光纤预制棒通常采用全合成法工艺来制备。从气相轴向沉积法(VAD)沉积、粉末棒脱羟、芯棒热处理等方面对该工艺进行了讨论。通过合理控制芯棒的d/a值、粉末棒密度以及优化粉末棒脱羟与芯棒酸蚀工艺等,可有效消除由低水峰光纤预制棒拉制的G.652D光纤在1 383nm波长处的水峰,使其满足密集型光波复用技术(DWDM)的运行需求,从而提高网络容量与传输速率。
Low water peak optical fiber preform is made by total synthesis process.It discusses from the aspects of VAD process,de-hydroxylation of soot,heat-treatment of core rod and so on.By controlling both d/aratio of the core rod and the density of soot as well as optimizing the process of soot de-hydroxylation and acid etching,reasonably,the G.652 Doptical fiber drawn by low water peak optical fiber preform can effectively eliminate the water peak at 1 383 nm and meet the requirement of DWDM technology.As a result,the G.652 Doptical fiber can improves the capacity and transmission speed of networks.
