ABSTRACT:
A glass optical waveguide preform is prepared by chemical reaction of vapor ingredients within a bait tube. As the reactants flow through the bait tube, a hot zone traverses the tube to cause the deposition of soot in a section of the tube downstream of the hot zone. An axially disposed heater enhances the thermophoresis effect within the tube, thereby increasing deposition rate and efficiency.
