Abstract

In submarine communications cables having a copper tube surrounding optical conductors, an armoring that surrounds the tube and is made of braided strands, a jacket layer made for example of a copper tube and external insulation, the jacket layer of copper or copper tube is complicated and expensive to produce and the copper jacket layer impairs the flexibility of the submarine communications cable. The invention provides for the copper jacket layer around the strands of the armoring to be replaced by a wrapped layer formed by at least one thin, flexible band that can be easily wrapped like a tape around the strands of the armoring, and the wrapped layer formed from the at least one thin, flexible band increases the flexibility of the submarine communications cable.
