Abstract: A cable joint for a multi-core cable including an outer sheath, at least one electric pilot line, at least one optical fiber line, and several cable cores. Both the electric pilot line and the optical fiber line are disposed in protective tubing. Each of the cores of the cable is electrically connected to respective cores of another electric cable, and the connection between the respective cores resides within a casing. Additionally, the electric pilot line, optical fiber, and protective tubing elements of the cable are connected to the corresponding structures of the other electric cable. The connection of these structures resides outside of the casing.
