ABSTRACT:
An undersea optical fiber cable with a protective metal casing around the optical fibers 1. The casing includes a stranded assembly 3 of high-tensile metal wires of polygonal cross-section 3A forming an arch structure. The side (4) which is turned towards the axis of the cable is shorter than the outwardly-turned side 5, and intermediate sides 6 touch or interlock. A metal outer tube 7 is formed by skelping a tape to produce a cylinder and then welding the longitudinal edges thereof. The metal casing is filled with a liquid 4A whose density is close to that of water and whose viscosity is close to that of glycerine. The overall density of the cable is slightly higher than that of water.
