B-2-19444M/KK/78 ABSTRACT OF THE DISCLOSURE Fibers especially suitable for use in optical communi- cations are manufactured according to a spinning process. Contamination of the fiber material by the carbon or graphite heating element is prevented by utilizing a glassy carbon or pyrolitic graphite containing little or no detached carbon as the heating element. The quality of drawn optical fibers is enhanced by utilizing an oven having an interior surface free of discontinuous or stepped portions.
