ABSTRACT:
An optical fiber cable comprises a stacked plurality of optical fiber ribbons each including a plurality of optical fibers disposed side by side in substantially the same plane and all embedded in a common covering or matrix of the ribbon. A protective outer sheath protects the cable against radial compression loads. Reinforcing members withstand traction loads applied to the cable, which further comprises filler members of a material based on reinforcing fibers and having a coefficient of expansion similar to that of the optical fibers embedded in a connecting matrix. The filler members occupy all or part of a volume delimited by the outside surface of the stacked ribbons and by the inside surface of the outer sheath so that the combination of the stack and the filler members has an external contour in cross-section that is substantially circular. The filler members protect the ribbons against radial and longitudinal loads applied to the cable and oppose contraction of the cable by more than 0.2%.
