A marine cable for a fiber optic waveguide with regenerator supply. A marine cable for a fiber optic waveguide must be provided with an electrical conductor for energy supply, in order to supply energy to the regenerators. For this purpose, the optical transmission elements are surrounded by a stranded layer of metal wires with good conductivity, which serve to supply energy. The stranded layer of metal wires with good conductivity is surrounded by an insulation layer, which in turn is protected by a stranded layer of sheathing wires. Both of the stranded layers of wires are embedded in a layer of a plastic, water-repellent material. The outer casing of the cable is formed by a metal composite layer sheath. The marine cable for a fiber optic waveguide with regenerator supply line, as described, can, for example, be laid down as an intercontinental cable.
A marine cable for a fiber optic waveguide with a regenerator supply line, the marine cable having a central LWL-bundle-conductor wire that is surrounded by at least one stranded layer of high-tensile sheathing wires and by a watertight metal casing, wherein the marine cable further comprises, within the stranded layer of high-tensile sheathing wires, an inner SZ-stranded layer of high-tensile sheathing wires, an inner SZ-stranded layer of eonduction embedded in a plastic, water-repellent embedding material, an insulation layer being disposed between the inner stranded layer and the sheathing wires, the embedding material having a specific electrical resistance smaller by at least one order of magnitude than that of the insulation layer.
A method for the manufacture of a marine cable for a fiber optic waveguide with a regenerator supply line, the marine cable having a central LWL-bundle-conductor wire surrounded by at least one stranded layer of high-tensile sheathing wires and by a watertight metal casing, wherein the marine cable further comprises, within the stranded layer of high-tensile sheathing wires, an inner SZ-stranded layer of conductive metal wires embedded in a plastic, water-repellent embedding material, an insulation layer being disposed between the inner stranded layer and the sheathing wires, the embedding material having a specific electrical resistance smaller by at least one order of magnitude than that of the insulation layer, the method comprising the steps of:
