ABSTRACT:
A glass preform for an optical fiber having homogeneous distribution of bulk density in its radial direction is produced by a method comprising forming fine glass particles by jetting a gaseous glass material and a fuel gas from a burner, depositing the fine glass particles on a seed rod to form a soot rod with measuring a temperature of a part of the soot rod on which the glass particles are being deposited so as to control said temperature, and then sintering the soot rod to obtain a transparent glass preform.
