Abstract
It is disclosed a figure of eight cable comprising a first cable element comprising a first core enclosed by a first outer sheath, a second cable element comprising a second core enclosed by a second outer sheath and a web joining the first and second outer sheaths so as to provide the cable with a major plane of symmetry X which comprises the longitudinal axes of the first and second cable elements. The cable also comprises at least one strength member embedded within the first or second outer sheath. All the strength members of the cable are substantially located on the major plane of symmetry X of the cable.
Claims14
A figure of eight cable comprising:
- a first cable element longitudinally extending along a first longitudinal axis and comprising a first core and a first outer sheath enclosing said first core, wherein said first core is an electrical core and comprises at least two stranded insulated electrical conductors;
- a second cable element longitudinally extending along a second longitudinal axis and comprising a second core and a second outer sheath enclosing said second core, wherein said second core is an optical core and comprises at least one optical fiber;
- a web joining said first outer sheath and said second outer sheath so as to provide said cable with a major plane of symmetry comprising the longitudinal axes of the first and second cable elements, wherein the web, the first outer sheath, and the second outer sheath are formed as a monolithic structure;
- and
- at least one strength member embedded within said first outer sheath or said second outer sheath,
- wherein all strength members comprised in said cable are substantially located on said major plane of symmetry;
- wherein said cable includes only one strength member;
- and
- wherein said one strength member is disposed within said first outer sheath or said second outer sheath at a position diametrically opposing said web.
