Abstract

Improvements in the underground lines of optical fiber cables constituted by an optical fiber cable line inside a flexible tubular conduit, the outer surface of the cable and the inner surface of the conduit having a low coefficient of friction in such a way that, once the duct has been introduced into a hole drilled in the ground, said duct having already inside the fiber cable (or a draft cable for the subsequent introduction of a fiber cable) can the piece of cable be removed and replaced by another identical one.
