Joints for optical fiber, submarine cables in which the tensile resistant element is centrally located in the cables, rather than at the exterior of the cables, and all spaces between the cable elements are filled with a substantially incompressible fluid. In the joint, the end of the tensile resistant element of one cable is joined to the end of the tensile resistant element of the other cable by a tubular clamp which is surrounded by a plastic layer having through-cavities in which the optical fibers are received and joined. If the optical fibers are in fluid filled tubes, the tubes are connected by further fluid-filled tubes surrounding the optical fiber connections. The plastic layer may be surrounded by a further plastic layer, and the cable metal sheaths are interconnected by a metal tube in watertight relation to the sheaths. The metal tube is surrounded by a plastic sheath and if desired, other layers, other than an armor which, by itself, can sustain the water pressure, may surround the plastic sheath. |
