Abstract: The invention relates to a method for economically producing a quartz glass rod consisting of synthetic quartz glass with a radially and axially homogenous refractive index curve. According to the invention, a whole cylinder consisting of quartz glass is coated with a coating tube consisting of porous glass, the latter shrinking onto the whole cylinder during sintering. The coating tube has a predetermined refractive index which ensures that there is a maximum increase in the refractive index value of 0.001 in the area of a contact surface between the whole cylinder and the shrank-on coating cylinder. A solid quartz glass rod produced in this way is characterized by a homogenous refractive index distribution in an axial and radial direction and comprises a whole cylinder consisting of synthetic quartz glass which is encased in a quartz glass layer formed by a coating tube consisting of porous quartz glass that is sintered and shrunk on with a maximum increase in the refractive index of 0.001 in the area of a contact surface. The inventive quartz glass rod is used for economically producing a preform for multimode fiber optical waveguides.

Abstract: According to an embodiment of the invention a method of manufacturing optical fiber cane comprises the steps of: (i) providing a core rod manufactured of relatively low viscosity glass; (ii) depositing SiO2 based soot around the core rod to form a soot preform, the soot being of relatively high viscosity material such that the softening point of the low viscosity glass is at least 200°C lower than the viscosity of the high viscosity outer core region; and (iii) consolidating the soot of the soot perform by exposure to hot zone at temperatures of 1000°C-1600°C. The soot is consolidated by heating the outer portion of the soot perform at a relatively fast heating rate, the heating rate being sufficient to densify the soot, so as to render the densified material with enough rigidity to confine the heated core rod and to prevent the heated core rod from puddling.
