ABSTRACT:
The vitreous material, e.g. silica, is deposited on the inner surface of the tube from a hot, intense, inductive plasma, which plasma is formed by utilization of wavelengths substantially longer than the diameter of the plasma. The process may be employed in the production of preform tubes or step or graded index optical fiber manufacture by gradually varying the contents of the vapor introduced into the plasma.
