Abstract
A method of fabricating an optical fiber preform includes an operation of glazing the outside surface of the preform using inductive heating, of the plasma torch type, for localized heating of the preform. A flow of gas between the plasma and the preform in the area of the outside face of the preform on which the plasma impinges reduces the power of the plasma in this outside surface area.
