    Abstract: Filament in tube and stick in tube processes of forming optical fiber are described. A solid or monolithic core feedstock (110) is disposed in a hollow cladding structure (112) to form a loosely filled cladding structure. The filled cladding structure is heated to a draw temperature approximately equal to the softening temperature of the cladding structure. The feedstock (110) melts and fills the heated portion of the cladding structure forming a filled core which can then be drawn into optical fiber or to an optical can which can then be further overclad consolidated and drawn into fiber. Feedstock (110) and cladding structures (112) having widely varying coefficients of expansion may be employed. The resulting fiber can be readily designed to be fused to existing installed fibers.

    Abstract: A method of making a glass article such as an optical waveguide preform is disclosed. The method comprises drawing a rod in at least two steps. In the first step an elongated, consolidated preform having an aperture therethrough is drawn to a reduced diameter preform. The second step involves drawing the reduced diameter preform into a rod, preferably at a lower temperature than the first step. The method substantially reduces the formation of inclusions in the glass article during drawing.
