Abstract
An optical cable comprises a longitudinally extending flexible central reinforcing member, e.g. a steel wire or wires; a layer of compressible material, such as cellular rubber or cellular plastics material, surrounding the reinforcing member; a plurality of separate optical fibres stranded side by side about the central reinforcing member in such a way that each optical fibre is in contact with the layer of compressible material; and, surrounding the optical fibres, an outer protective sheath. When the separate optical fibres are subjected to a tensile force, at least some of them can move transversely inwardly of the cable to compress the compressible material and thereby reduce the strain that would otherwise be imparted to the fibres.
