Abstract
A cable comprising a central armour, a dielectric helically grooved core and optical fibres housed in said grooves which are formed with a lip protruding from one edge is produced by extrusion of the profiled core on the armour heating of the core, laying of one fibre within one groove with the aid of a fibre guide controlled by a positioning slot in said core, bending the lip to close the groove outwardly and repeating said heating, laying, etc. . . for each fibre and taping the structure.
