Abstract:
Glass soot (130) is deposited on a glass rod by a burner (140). The body is stretched (126). More depositing and stretching is effected. The final body is then drawn into a fiber.
Abstract:
A plasma flame is generated in an interior volume of a tubular member to be a radially directed plasma flame, directed to an inside surface of the tubular member, and reagent chemicals are injected to form soot particles, and the soot particles are deposited on the inner surface by the plasma flame. The plasma flame is generated by establishing an electromagnetic field in a region in the tube interior and inserting a plasma gas feeder nozzle into the tube interior, with the nozzle structure to emit plasma gas in a manner forming the radially directed plasma flame.

Abstract:
A single plasma burner (4a) deposits soot material on multiple rotating parallel targets (2a, 2b, 2c). All of the targets are grown simultaneously. The result is multiple preforms for optical fibers.

Abstract:
A plurality of glass deposition targets are rotated simultaneously and a first plasma torch, having a coil diameter larger than the sum of the target diameters, deposits glass simultaneously on the plurality. After the diameter of the targets reaches a threshold a second plasma torch is used. The diameter of the second plasma torch can provide for simultaneous deposition. In a further embodiment, after the target diameter reaches a second threshold a third plasma torch is used. In a further embodiment the spacing between the axes of rotation of the targets is widened as the target diameter increases. In a still further embodiment a single plasma torch includes movable concentric tubes within its coil to selectively operate as any of a plurality of different diameter plasma torches.
