A system for fabricating an optical fiber preform including glazing the outside surface of the preform using inductive heating, the system including a plasma torch for localized heating of the preform during the glazing, and an injector for injecting into the plasma in the area of the outside face of the preform on which the plasma impinges a gas which is substantially free of silica particles to reduce the power of the plasma during the glazing operation.
