Abstract: In accordance with the invention, an optical fiber is made by the steps of providing an optical fiber preform having a longitudinal axis, rotating the preform about the axis, directing onto the preform a plasma torch which is reciprocated over a limited region parallel to the axis to define a heated region, and drawing a fiber from the heated region. Apparatus for making optical fiber comprises a rotatable mount for securing one end of a preform and rotating it about a vertical axis, a plasma torch for heating a drawing region on the preform, a positioning stage for moving the torch parallel to the vertical axis in a reciprocating manner, and a fiber drawing apparatus for drawing a fiber from the heated region of the preform.

Abstract: A refractory dielectric body is heated with a plasma fireball at conditions which do not result in substantial removal of a surface portion of the body, yet which are sufficient to reduce both surface and bulk impurities. Typically, the body is treated with the plasma in the absence of simultaneous deposition of material onto the body. Advantageously, an isothermal, oxygen or oxygen-containing plasma is utilized. The invention is useful for reducing chlorine impurities by at least about 30% to a depth of at least about 10 .mu.m, with accompanying reduction of hydroxyl impurities. The invention thus provides a useful method for reducing the concentration of impurities that contribute to imperfections during the process of drawing fiber from an optical fiber preform, without requiring substantial removal of the surface of the preform.

Abstract: High silica content optical glasses, containing more volatile oxides such as GeO.sub.2 and B.sub.2 O.sub.3, are produced by plasma fusion of powders without inordinately high loss of the more volatile constituents. The powders are produced by a process including the heat treatment of intimately mixed materials, which include the glass forming constituents. Small quantities of GeO.sub.2 are included in borosilicate glass to suppress bubble formation. Pairs of glass compositions have been found, with sufficient index of refraction difference to produce guidance in optical transmission lines, while possessing sufficient thermal expansion match to reduce stresses in the line.
