A method is disclosed for manufacturing an optical fiber cable element having plurality of optical fibers which are arranged with excess length inside a pressure-tight metal tube. Means are provided inside the metal tube for protecting the optical fibers and for longitudinal sealing. The optical fibers are first embedded in a soft or compressible compound to form a cable element core. The outside, diameter of the cable element core generally corresponds to the inside diameter of the metal tube in the finished cable and the optical fibers being present with excess length in the cable element core. A metal band is subsequently continuously formed into a slotted tube surrounding the cable element core. A distance remains between the cable element core and the tube. The slotted tube is welded together and the tube is drawn down onto the cable element core.
