Abstract
PURPOSE:In manufacturing optical fibers with the use of vapor phase chemical reaction, it is contemplated to produce low-loss optical fibers having a full circular shape and less diametrical fluctuations by integrating both processes for the fabrication of a perform and for the wire drawing.
