ABSTRACT:
A process for producing optical fibers of high tensile strength, wherein the fiber is pulled from a glass mass of halide glass and includes surrounding the fiber and mass with a dry gas atmosphere containing a drying agent which reacts with moisture and this dry gas atmosphere includes fluorine-containing agents, in particular NF.sub.3, as the drying agent.
