Abstract

It is disclosed a cable assembly comprising a common figure-8 outer jacket comprising a first lobe and a second lobe, wherein the first lobe surrounds an electric core with a relevant first extruded inner sheath housing a strength member; and the second lobe surrounds an optical core with a relevant second extruded inner sheath.

First claim

The invention claimed is:

1. A cable assembly comprising:
a figure-8 outer jacket comprising a first lobe and a second lobe;
an electric core, two strength members, and a first extruded inner sheath housing said electric core and said two strength members, wherein the first lobe surrounds the first extruded inner sheath; and
an optical core and a second extruded inner sheath housing said optical core, wherein the second lobe surrounds the second extruded inner sheath,
wherein said electric core includes a plurality of power conductors, and
wherein said electric core includes a telecommunication conductor.

2. The cable assembly of claim 1 , wherein the figure-8 outer jacket embeds a rip-cord.

3. The cable assembly of claim 2 , wherein the figure-8 outer jacket embeds a rip-cord per each first and second lobe.

4. The cable assembly of claim 3 , wherein the rip-cord of the first lobe and the rip-cord of the second lobe are embedded into the figure-8 outer jacket at diametrically opposed positions.

5. The cable assembly of claim 1 , wherein said first extruded inner sheath and second extruded inner sheath have a thickness of at least 0.2 mm.

6. The cable assembly of claim 1 , wherein said figure-8 outer jacket comprises a web connecting the first lobe and the second lobe.

7. The cable assembly of claim 1 , wherein said figure-8 outer jacket has a thickness of from 0.5 mm to 1.0 mm.

8. The cable assembly of claim 1 , wherein the two strength members are positioned at diametrically opposed positions.

9. The cable assembly of claim 1 , wherein each of the two strength members is laid parallel to a first lobe longitudinal axis.

10. The cable assembly of claim 9 , wherein the two strength members are positioned at diametrically opposed positions.

11. The cable assembly of claim 1 , wherein the optical core comprises a plurality of optical fibres.

12. The cable assembly of claim 11 , wherein the optical core further comprises dielectric elements configured to protect the optical fibres.

13. A cable assembly comprising:
a figure-8 outer jacket comprising a first lobe and a second lobe;
an electric core, a strength member, and a first extruded inner sheath housing said electric core and said strength member, wherein the first lobe surrounds the first extruded inner sheath; and
an optical core and a second extruded inner sheath housing said optical core, wherein the second lobe surrounds the second extruded inner sheath,
wherein the figure-8 outer jacket is removable,
wherein the first extruded inner sheath constitutes a first self-standing cable when the figure-8 outer jacket is removed, and
wherein the second extruded inner sheath constitutes a second self-standing cable when the figure-8 outer jacket is removed.

14. The cable assembly of claim 13 , wherein the figure-8 outer jacket embeds a rip-cord.

15. The cable assembly of claim 13 , wherein the figure-8 outer jacket embeds a rip-cord per each said first lobe and said second lobe.

16. The cable assembly of claim 13 ,
wherein the first extruded inner sheath houses said strength member and another strength member, and
wherein the strength members are positioned at diametrically opposed positions.

17. The cable assembly of claim 13 , wherein said figure-8 outer jacket comprises a web connecting the first lobe and the second lobe.

18. The cable assembly of claim 13 , wherein the optical core comprises a plurality of optical fibres.

19. The cable assembly of claim 13 , wherein said electric core includes a plurality of power conductors.

20. The cable assembly of claim 13 , wherein said electric core includes a telecommunication conductor.
