Abstract: A method for producing an optical cable with a metal tube and at least one optical fiber arranged in the metal tube, wherein optical fiber(s) are inserted into a slotted tube, the longitudinal slot in the slotted tube is welded, and the diameter of the welded tube is reduced. After the reducing operation, the welded tube is gripped by a draw-off device and conveyed in the finishing direction and wound up onto a draw-off disk. Between the draw-off device (10) and the draw-off disk (11), a force which causes elastic elongation of the metal tube (13) in the finishing direction is applied by the draw-off disk (11), and the extent of the elastic elongation is regulated through this force.
