Submarine optical fiber line with interconnected different cable types
First Claim
1. A submarine optical fiber cable line comprising:
- an opto-electronic repeater having a water-tight envelope, said envelope being made of materials and having dimensions which permit it to withstand stresses imparted to it while it is being laid underwater and after it is laid underwater;
at least two submarine optical fiber cables connected at their ends to, respectively, one end of said repeater and the other end of said repeater, at least one of said cables connected to said repeater being an optical fiber cable having a central rope capable of withstanding the stresses imparted to the cable during laying, having longitudinally extending optical fibers disposed around said rope and having a sheath around said optical fibers, said one cable being without armor outside said optical fibers capable of withstanding, by itself, the stresses imparted to said one cable during laying and after it is laid; and
a tubular body intermediate and interconnecting said one cable with said repeater, said tubular body being mechanically connected at one end to said envelope, being mechanically connected at its other end to said sheath and having a strength sufficient to withstand the stresses imparted thereto by said repeater and said one cable and by the water in which it is laid, said tubular body having a rigid partition secured thereto and extending transversely to the bore of said tubular body, said partition being mechanically connected to said rope and having a strength sufficient to withstand the stresses imparted to said rope during the laying of said one cable and after it is laid and said partition having at least one through-opening for the passage of said optical fibers of said one cable.

Abstract
A submarine, optical fiber telecommunication line having optical fiber cables with external armor interconnected with optical fiber cables with only internal armor by opto-electronic repeaters and tubular bodies. The repeaters, the tubular bodies and the cables can withstand the tensile and hydrostatic stresses to which they are subjected during laying and after laying. At the shore ends, the repeaters are mechanically connected at one of their ends to cables with external armor. The other ends of the repeaters are mechanically connected to the tubular bodies which are mechanically connected to the sheaths and the internal armor of cables with only internal armor. The tubular body has an internal partition to which the internal armor is mechanically connected and has an internal sealing plug for preventing axial flow of water.
