  • METHOD OF REDUCING BREAK SOURCES IN DRAWN FIBERS BY ACTIVE OXIDATION OF CONTAMINANTS IN A REDUCING ATMOSHERE
    Publication number: 20020029591
    Abstract: A class preform (30) for making optical waveguides has surface impurities such as silicon carbide or silicon nitride. The preform is drawn in a furnace (12) that is supplied with oxygen via a conduit (40). The oxygen causes the impurities to oxidize and not effect the strength of the fiber.

  • Method of reducing break sources in drawn fibers by active oxidation of contaminants in a reducing atmosphere
    Patent number: 6345519
    Abstract: In connection with drawing a fiber in a drawing portion of a drawing device having a refractory, oxide component, a method and apparatus provide an environment in the drawing portion that causes active oxidation of a refractory contaminant on a blank. The active oxidation of the refractory contaminant causes it to corrode away during drawing.
