  • System and method for measuring stress during processing of an optical fiber
    Patent number: 6490378
    Abstract: A system and method for measuring stress exerted on an optical fiber including providing an optical fiber that includes a fiber optic sensor, and exposing the optical fiber and the fiber optic sensor to various stresses associated with the process by moving the optical fiber and the fiber optic sensor through the process to be measured. The system and method further includes transmitting a source light through the optical fiber as the optical fiber and the fiber optic sensor are exposed to various stresses, receiving a return light signal from the fiber optic sensor as the optical fiber and the fiber optic sensor are exposed to various stresses, and comparing the source light signal to the return light signal for determining the stress exerted on the optical fiber.
    Type: Grant

  • 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.
