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.
Claims12
In an optical cable comprising a plurality of bundle elements, each bundle element having a plurality of light waveguides arranged within a deformable plastic sheath, the improvements comprising the light waveguides being mechanically combined in the form of light waveguide pairs, and the individual light waveguide pairs of a bundle element being arranged radially movable relative to one another and relative to an outer, highly elastic plastic protective sheath of the bundle element, said protective sheath being composed of a rubber-elastic material and having a modulus of elasticity in a range of between 50 and 500 N/mm.sup.2.
In an optical waveguide according to claim 3, wherein said common coating is composed of an ultraviolet-curable acrylate.
In an optical cable according to claim 11, wherein the dead space is approximately 60%.
