Abstract

A cable includes a tubular jacket which surrounds a plurality of protection tubes in which optical fibers are accommodated in groups and have a relative freedom of movement. These tubes are disposed in layers in which they are disposed in a helix. The cable includes at least one layer made up of an assembly of tubes which have an outside diameter smaller than that of the tubes of a layer that they surround and the tubes of the two layers all contain the same number of optical fibers.
