  • Methods for manufacturing low water peak optical waveguide incorporating a porous core mandrel
    Patent number: 8205472
    Abstract: A method of manufacturing a cylindrical glass optical waveguide preform having a low water content centerline region, for use in the manufacture of optical waveguide fiber, is disclosed. The centerline region of the glass optical waveguide preform has a water content sufficiently low such that an optical waveguide fiber producible from the glass optical waveguide preform of the present invention exhibits an optical attenuation of less than about 0.35 dB/km, and preferably less than about 0.31 dB/km, at a measured wavelength of 1380 nm. Method of manufacture of a porous core mandrel used in the manufacture of such a glass optical waveguide preform is also disclosed.
    Type: Grant
    Filed: March 18, 2011
    Date of Patent: June 26, 2012
    Assignee: ASI/Silica Machinery, LLC
    Inventors: David McDonald Stirling, Franklin W. Dabby, Gordon Randall Gould, Henry Willner
