<p>A method for producing an optical fiber preform comprises forming glass soot particles by jetting and combusting a gaseous glass-forming material and a fuel gas from a burner (11) in the presence of oxygen, depositing the glass soot particles on a deposition rod (10) while rotating the deposition rod (10) about its axis (8) and reciprocating the burner (11) in parallel to the deposition rod so as to form the preform, and varying at least one of the translation velocity of the burner (11) and the rotation velocity of the rod (10) so as to obtain a predetermined radial soot density distribution in the preform.</p> |
