FABRICATION OF OPTICAL FIBERS WITH IMPROVED CROSS SECTIONAL CIRCULARITY Abstract of the Disclosure Optical fibers are produced with improved cross sectional circularity. In the course of the fabrication process, the tubular preform from which the fibers are drawn, is collapsed under positive internal pressure. This removes most cross sectional noncircularities that may have developed during fabrication of the preform, and also ensures the collapse of the preform to a structure with circular cross section.
