Abstract
A method of forming optical fibers in a continuous manufacturing process employs a heated mandrel with a predetermined taper at one end. Glass forming materials are applied to the mandrel by chemical vapor deposition along the taper to provide a corresponding glass concentration gradient along the taper. The molten glass materials are drawn in a continuous process without an intermediate preform stage.
