Abstract
A hollow cylindrical, watertight casing housing optoelectronic repeater components, having optical fibers extending therefrom, and having a bore in which a tension resisting rope is received and is insulated from the wall of the bore. The casing is enclosed by a water-tight, tubular box which has a pair of cylindrical bodies extending therefrom, one at each end of the box. Each cylindrical body has a centrally disposed length of rope surrounded by polymeric material in which optical fibers are embedded, and the polymeric material is surrounded by a metallic sheath. The optical fibers of the cylindrical bodies are connected within the box to the optical fibers extending from the casing. The lengths of rope of the bodies are mechanically connected at one end respectively to opposite ends of the rope in the bore and at the opposite end respectively to ropes of submarine optical fiber cables having similar ropes, optical fibers and a metallic sheath. The optical fibers of the bodies are connected to the optical fibers of the cables, and the sheaths of the bodies are connected to the sheaths of the cables. Any otherwise empty spaces within the box are filled with a substantially incompressible fluid.
