    Abstract: A method of forming an optical fiber by heat treating a consolidated glass article, doped with at least one refractive index-modifying dopant, at a temperature between about 1100?C and 1400?C and for a time between about 1 hour and 12 hours in a helium-containing atmosphere. The consolidated glass article is an optical fiber precursor. The optical fiber drawn from the heat treated consolidated glass article exhibits an attenuation lower than an optical fiber drawn from a substantially identical optical fiber precursor that has not been heat treated in accordance with the present invention.

    Abstract: A method of manufacturing an optical waveguide perform includes exposing a soot preform to an atmosphere including a chlorine-containing compound and thereby doping the soot preform with chlorine, wherein the absolute pressure of the atmosphere is greater than about 1.013 x 10 2 kPa. An apparatus for manufacturing an optical waveguide preform using a soot preform includes a furnace defining a chamber adapted to contain the soot preform and including a heating device operable to heat the chamber. A fluid control system is operable to provide an atmosphere including a chlorine-containing compound in the chamber at an absolute pressure of greater than about 1.013 x 10 2 kPa.
