Abstract
The optical fiber cable includes an assembly of at least two flexible tubes accommodating optical fibers, a sheath enveloping the assembly of tubes, and at least one filamentary form strength member at the periphery of the assembly of tubes. The tubes preferably extend in the sheath in a helical or an SZ assembly. The tubes are stuck together. The sheath is preferably made of polyethylene and the tubes are preferably made of polyvinyl chloride (PVC) or a thermoplastics elastomer with diol flexible segments. In this method, when extruding the sheath around the tubes, the temperature at which the material of the sheath is extruded is adjusted to cause the tubes to stick together.
