Abstract: 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.
