Abstract

Claims (27)

1. Cabling comprising:

a jacket having an inner surface defining a core, the core extending along a cable axis; and

a separator positioned in the core, the separator having at least one shield segment defining at least portions of walls separating the core into a plurality of chambers each configured to receive at least one twisted wire pair, each shield segment including a metallic layer and a laminate layer, the laminate layer defining an exposed surface of the wall of the corresponding chamber, the shield segments extending from proximate to the inner surface of the jacket to the cable axis such that each metallic layer engages another metallic layer at the cable axis.

2. The cabling of claim 1 , wherein the shield segment engages the inner surface of the jacket and extends radially inward to the cable axis, the metallic layers engaging one another for the entire span from the inner surface of the jacket to the cable axis.

3. The cabling of claim 1 , wherein the shield segment is folded over such that different sections of the metallic layer engage one another.

4. The cabling of claim 1 , wherein the at least one shield segment defines a first shield segment and a second shield segment, the first and second shield segments extend between first and second ends, the first ends being connected to one another such that the metallic layers of the first and second segments engage one another from the first ends to the cable axis.

5. The cabling of claim 1 , wherein the at least one shield segment defines a first shield segment and a second shield segment, the first and second shield segments extend between first and second ends, the metallic layers of the first and second shield segments engage one another from the first ends to the cable axis and from the second ends to the cable axis.

6. The cabling of claim 1 , wherein the at least one shield segment defines a first shield segment and a second shield segment, the first and second shield segments have substantially equal widths extending between first and second ends, the metallic layers of the first and second shield segments engaging one another for substantially the entire widths thereof.

7. The separator of claim 1 , wherein the at least one shield segment defines first and second shield segments being L-shaped with a base and a leg meeting at a corner, the first and second shield segments are oriented so that the bases abut one another, the corners of the first and second shield segments are both positioned at the cable axis such that the legs extend in opposite directions from one another.

8. The separator of claim 1 , wherein the at least one shield segment defines first, second, third and fourth shield segments, each shield segment having perpendicular legs intersecting at a corner, the corners of each shield segment meeting at the cable axis and the legs extending radially outward toward the jacket.

9. The separator of claim 1 , wherein the separator has a cruciform shape with generally radially extending legs meeting at the cable axis, the separator maintaining the cruciform shape when assembled with the wires.

10. A separator for separating wire pairs within cabling, the separator comprising:

a first shield segment including a first metallic layer and a first laminate layer, the first shield segment having a first width; and

a second shield segment including a second metallic layer and a second laminate layer, the second shield segment having a second width being substantially equal to the first width;

wherein the first and second shield segments are arranged such that the first metallic layer continuously engages the second metallic layer for substantially the entire first and second widths, the first laminate layer defines a first chamber within the cabling configured to receive a first of the wire pairs and the second laminate layer defines a second chamber within the cabling configured to receive a second of the wire pairs, the first and second laminate layers exposed within the respective first and second chambers.

11. The separator of claim 10 , wherein the first and second shield segments are generally planar and cooperate to divide the cabling into two hemispheres.

12. Cabling comprising:

a jacket surrounding a core; and

a separator positioned in the core, the separator having at least one shield segment defining at least portions of walls separating the core into a plurality of chambers each configured to receive a plurality of twisted wire pairs, each shield segment including a metallic layer and a laminate layer, the laminate layer defining an exposed surface of the wall of the corresponding chamber.

13. The cabling of claim 12 , wherein each shield segment comprises a laminated metal tape.

14. The cabling of claim 12 , wherein the metallic layer provides shielding between adjacent chambers.

15. The cabling of claim 12 , wherein the separator is generally planar and has a width approximately equal to a diameter of the core.

16. The cabling of claim 12 , wherein the separator engages an inner surface of the jacket at opposed sides of the jacket.

17. The cabling of claim 12 , wherein the core extends along a cable axis, the separator extending from the cable axis in diametrically opposed directions.

18. The cabling of claim 12 , wherein the separator divides the core into hemispherically shaped chambers.

19. The cabling of claim 12 , wherein the separator includes a first shield segment and a second shield segment, the metallic layers of the first and second shield segments continuously engaging one another along substantially an entire width of each shield segment.

20. The cabling of claim 12 , wherein the metallic layer is thicker than the laminate layer.
