  • Vaporizers and apparatuses for forming glass optical fiber preforms comprising the same
    Patent number: 11649186
    Abstract: Vaporizers and systems for vaporizing liquid precursor for forming glass optical fiber preforms are provided. The vaporizer includes an expansion chamber at least partially enclosed by a side wall, the expansion chamber comprising an upper end and a lower end with the side wall disposed between the upper end and the lower end. The vaporizer further includes a closed-loop liquid delivery conduit positioned in the expansion chamber proximate to the upper end of the expansion chamber, wherein the closed-loop liquid delivery conduit comprises a plurality of nozzles oriented to direct a spray of liquid precursor onto an inner surface of the side wall. Further, the vaporizer includes at least one supply conduit positioned proximate the upper end of the expansion chamber and coupled to the closed-loop liquid delivery conduit, and a vapor delivery outlet coupled to the expansion chamber and configured to direct vaporized liquid precursor from the expansion chamber.

  • Tapered furnace muffles
    Patent number: 11242278
    Abstract: An optical fiber draw furnace muffle includes a body portion defining a substantially cylindrical cavity extending along a centerline axis of the muffle. A tapered portion has an interior surface which defines a first curved portion with a first radius of curvature and a second curved portion with a second radius of curvature. At least one of the first and second radii of curvature has a radius greater than a radius of the cylindrical cavity.

  • Purge device for an optical fiber draw system
    Patent number: 10773990
    Abstract: An optical fiber production system is provided which includes a slow-cooling device and a purge device positioned above the slow-cooling device. The purge device includes a tube defining an inlet. An optical fiber extends through the slow-cooling device and the purge device. The purge device is configured to inject a purge gas through the inlet and against the optical fiber.
