Abstract

The cable has a core consisting of at least one optical conductor, and armouring elements twisted around the core. In order to achieve the object of configuring this cable with a small diameter and low weight in such a way that negative effects of the tensile loading of the cable are kept from the optical fibres even without substantial excess lengths of the optical fibres, it is proposed that all the armouring elements are twisted around the core with the same direction of twist and with a length of twist lK which is smaller than 100 times the mean twist diameter dK of the armouring layer, and that the optical conductors led in the core are twisted with the same direction of twist as the armouring elements in such a way that the length of twist lF of the optical conductors twisted in a layer having a mean diameter dF is dimensioned according to the equation <IMAGE> X being a dimensionless number between 1.3 and 4. <IMAGE>
