    Abstract: One embodiment of the disclosure relates to a method of making an optical fiber comprising the steps of: (i) exposing a silica based preform with at least one porous glass region having soot density of r to a gas mixture comprising SiCl 4 having SiCl 4 mole fraction y SiCl4 (preferably of less than 0.03) at a doping temperature T dop such that parameter X is larger than 0.03 to form the chlorine treated preform, wherein X is defined as a function of density r, doping temperature T dop , SiCl4 mole fraction y SiCl4 , and the density p s of the fully densified soot layer; and (ii) exposing the chlorine treated preform to temperatures above 1400 °C to completely sinter the preform to produce sintered optical fiber preform with a chlorine doped region; and (iii) drawing an optical fiber from the sintered optical preform.
