Abstract: Disclosed is an optical fiber having a core with an alkali metal oxide dopant in an peak amount greater than about 0.002 wt. % and less than about 0.1 wt. %. The alkali metal oxide concentration varies with a radius of the optical fiber. By appropriately selecting the concentration of alkali metal oxide dopant in the core and the cladding, a low loss optical fiber may be obtained. Also disclosed are several methods of making the optical fiber including the steps of forming an alkali metal oxide-doped rod, and adding additional glass to form a draw perform. Preferably, the draw preform has a final outer dimension (d2), wherein an outer dimension (d1) of the rod is less than or equal to 0.06 times the final outer dimension (d2). In a preferred embodiment, the alkali metal oxide-doped rod is inserted into the centerline hole of a preform to form an assembly.

Abstract: Repositionable heater assemblies and methods of controlling temperature of glass in production lines using the repositionable heater assemblies are disclosed. The repositionable heater assembly includes a support frame, a first sled and a second sled each coupled to the support frame with bearing members that allow the first sled and the second sled to translate in a longitudinal direction. Each of the first sled and the second sled include at least one heating element, where the heating elements are spaced apart from the glass ribbon a spacing distance. The first and second sleds are movable in the longitudinal direction to controlling the spacing distance between the heating elements of the first sled and the second sled and the glass ribbon to manage temperature of the glass ribbon.

Abstract: An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force minimizes stress variability in the glass ribbon and improves ribbon shape control.
