LOW TEMPERATURE METHOD FOR MAKING OPTICAL FIBERS |
摘要 |
<p>A glass optical waveguide preform is formed by chemical reaction of gaseous and/or vaporized ingredients within a glass substrate tube. A reactant feed tube extends into a first end of the substrate tube. One of the reactants flows through the feed tube, and another flows through the annular channel between the feed and substrate tubes. The reactants combine just downstream of the end of the feed tube and react to form particulate material, at least a portion of which deposit in the substrate tube. The output end of the feed tube traverses the substrate tube so that the region of maximum soot deposition moves along the length of the substrate tube. A hot zone traverses the substrate tube in synchronism with the feed tube to sinter the deposited soot.</p> |
