The fluorine doping process of pure silica “soot” with various type of fluorine gases in the vapour-phase axial deposition (VAD) sintering process was investigated in detail. This investigation showed that the doping level is proportional to the

A single mode (SM) fiber with extremely low loss and sufficient long term reliability is indispensable for the coming ultra long span optical transmission system. As a promising candidate for such a high grade fiber, a pure silica core SM fiber has b
