Abstract

An optical cable comprising a plurality of bundle elements, each of which contains a plurality of light waveguides loosely arranged inside a deformable protective sheath. The light waveguides are combined in the form of light waveguide pairs and are fashioned as flat, ribbon-like structures, which are mobile in a radial direction relative to one another and relative to the outer sheath of the bundle element. The protective sheath is expediently composed of a rubber-elastic material, whose modulus elasticity is selected to be in a range of 50-500 N/mm.sup.2.
