A method and apparatus of fabricating an optical fibre by means of the double crucible method is described, in which a double crucible (1, 13) is used of which at least the inner crucible (1) has a double-walled construction. The double wall accommodates a metal wire coil (3). During the fabrication of the optical fibre (21) the core glass (10) is heated by means of a high-frequency electric field and the crucible wall (1) is cooled with a cooling liquid. |
