Abstract

Process for forming an optical fiber, which comprises holding a cylindrical tube of fused silica and is characterized in that a mixed vapor comprising oxygen, silicon tetrachloride, an adulterant and a flux is formed and mixed vapor is passed through the tube; the tube is heated to form a hot zone that travels along the tube so that the vapor forms a deposit adjacent to the hot zone and the tank melts to form a layer on the inner surface of the tube, using an adulterant to produce a higher refractive index in the layer than in the tube; using a flux to reduce the melting temperature of the deposit; the heating of the tube is repeated to form a plurality of layers; the tube is heated above the softening temperature to fold the tube into a rod; and the rod is subjected to tension to form an optical fiber.
