Abstract
An optical fiber is formed by continuously coating a precursor core filam with a glass-forming coating. The precursor filament is continuously moved from a storage reel through a stationary coating station. The filament is then moved through a stationary glass-forming station and is continuously processed to convert the coating to a glass, with the core either removed from the fiber during glass forming or becoming an integral part of the ultimate fiber during glass forming. The glass fiber is then moved continuously through a glass densification station and is densified in a continuous process. The fiber is thereafter provided with a protective coating as it moves through a stationary coating station and the completed optical fiber is continuously reeled.
