Abstract
A joint for interconnecting a pair of optical fiber, submarine cables which have a central armor sufficient to withstand tensile stresses applied to the cables during use, i.e., laying, recovery and operation, which have optical fibers loosely disposed in channels in a plastic layer around the central armor and which have all otherwise empty spaces filled with a substantially incompressible fluid. The joint comprises a metal ferrule or a weld mechanically interconnecting the ends of the armors of the cables. A plastic joint sheath surrounds the interconnection of the armors and has channels which interconnect the respective channels of the cables. The optical fibers are loosely received in and interconnected within the joint sheath channels. Any otherwise empty spaces within the plastic joint sheath are filled with a substantially incompressible fluid. The cables and the joint sheath are without external armor which, by itself, can withstand the tensile stresses and hydrostatic pressures to which the cables are subjected during use.
