A method of manufacturing an optical fiber includes: disposing an axially extending preform structure on a support structure; directing a gas mixture along a major axis of the preform structure in a first axial direction; disposing a heating device proximate to the preform structure; and activating the heating device and moving the heating device along the major axis in a second axial direction to heat the preform structure and deposit at least one layer of material on the preform structure, the second axial direction being opposite to the first axial direction.
