ABSTRACT:
A method of fabricating an optical fiber by means of the double crucible method. A double crucible is used of which at least the inner crucible has a double-walled construction. The double wall accommodates a metal wire coil. During the fabrication of the optical fiber the core glass is heated by means of a high-frequency electric field and the crucible wall is cooled with a cooling liquid.
