Title: SUBMARINE COMMUNICATIONS CABLE, AND METHOD AND DEVICE FOR THE PRODUCTION THEREOF
Abstract:
Submarine communications cables have a copper tube (11) surrounding optical conductors (10), a reinforcement, surrounding the tube (11), made of braided strands (13), a jacket layer made for example of a copper tube, and external insulation (18). It is complicated and expensive to form the jacket layer from copper or a copper tube. Furthermore, the flexibility of the submarine communications cable suffers under the jacket layer made of copper. The invention provides for the copper jacket layer around the strands (13) of the reinforcement to be replaced by a wrapped layer (14) formed from at least one band (15, 17). The thin, flexible band (15, 17) can be easily wrapped like a tape around the strands (13) of the reinforcement. Furthermore, the wrapped layer (14) formed from the at least one thin band (15, 17) increases the flexibility of the submarine communications cable.
