Disclosed is an improved optical fiber cable, for telecommunications, which consists, as laying elements, of a plurality of loose tubes, placed longitudinally around a central reinforcement, in order to form a pultruded tubulated assembly. The improvement lies in the following elements which are placed onto said assembly: an aramide fiber layer or a fiber glass layer to obtain a better tension during the cable installation; then one or several plastic covers placed longitudinally to support one or several corrugated metal ribbons that are peripherically incorporated to the assembly; and a final plastic cover, the loose tubes containing one or several optical fibers with freedom of movement and a gel filling both in the inner section as well as in the outer section of the loose tubes.
