In a process for the manufacture of an optical cable consisting of a metal pipe, in which at least one optical fiber is arranged, a metal strip drawn from a supply coil is gradually shaped into a slot pipe. The optical fiber drawn from an additional supply coil is fed to the still open slot pipe, the longitudinal slot of the slot pipe is welded and the diameter of the welded pipe is reduced. The metal pipe is elastically elongated at least after the reduction. The diameter of the pipe is thereby reduced in at least two stages, the value of the reduction being greatest in the last stage. |
