Abstract
A halide glass core fiber is clad by providing two melts that selectively join to form the molten clad fiber in a temperature range from 580.degree. C. to 600.degree. C. A separate heating means controls the fiber melt at the die nozzle. Because of the low viscosity and the narrow proto congelation temperature zone, the clad fiber is extruded and drawn in the vertical direction counter the effect of gravity.
