    摘要: Energy efficient process and apparatus are disclosed for forming migration free glass fiber packages composed of fibers (16) bearing substantially uniform coatings of size composition. Heated air from around the fiber forming bushing (12) is drawn into a chamber (56) through which the glass fibers (16) pass to cause the water or solvent in the applied size to be evaporated. The flow of heated air through the chamber (56) is regulated so as to obtain substantially uniform size application to the fibers (16).

    摘要: Touch assembly and method are described for fabricating a spliced low-loss, high-strength optical transmission line. A first fiber is spliced to a second fiber at a splice point. The spliced fibers are loaded into a heat treatment station, where a gas torch flame is used to thermally treat a splice region including the splice point, with the thermal treatment reducing splice loss due to expansion and mismatch of modefields between the first and second fibers. While heating the splice region, a dry gas is purged around the torch flame during the heat treatment process to avoid water at the surface of the spliced fibers. A purging gas is fed to the torch flame to purge dust particles from the flame, and after the heat treatment has been completed, the torch flame is used to restore the glass surface of the spliced fibers. Additionally described are torch assemblies for fabricating low-loss, high-strength optical fiber transmission lines.

    摘要: A fiber optic coupler (51) is automatically manufactured under the control of a programmable controller (79). A fiber feed device (26) sends fibers (16-17) through a tube (50). Fibers (16-17) are stored in the tube (50). Chucks (57-58) pull in opposite directions to form a tapered coupling region. Epoxy dispensers dispense epoxy into uncollapsed ends of the coupling tube (12) bore. A UV light sources (70) cures the epoxy. The control of the apparatus by programmable controller eliminates operator inconsistencies and improves process reproducibility.
