Abstract

A separator for a communication cable that comprises a body that includes at least first and second segments adapted to define a plurality of quadrants in the communication cable. The segments are substantially perpendicular to each other and define a junction point of the segments. Each of the segments includes a main portion and a terminal end remote from the junction point of the segments. Each of the terminal ends has a shape such that each of the terminal ends is wider than the main portions of the segments. At least one air pocket is defined between the terminal ends of the segments. The air pocket includes a gap sized such that the air pocket is substantially enclosed.

Claims

1. A separator for a communication cable, comprising:

a body including,

at least first and second segments adapted to define a plurality of quadrants in the communication cable, said at least first and second segments being substantially perpendicular to each other and defining a junction point of said at least first and second segments,

each of said at least first and second segments including a main portion and a terminal end remote from said junction point of said segments, and each of said terminal ends having a shape such that each of said terminal ends is wider than said main portions of said segments, and

at least one air pocket defined between said terminal ends of said at least first and second segments, said air pocket including a gap sized such that said air pocket is substantially enclosed.

2. A separator according to claim 1, wherein

said width of each of said terminal ends increases toward said junction point of said segments.

3. A separator according to claim 1, wherein

each of said terminal ends has a generally triangular cross-sectional shape.

4. A separator according to claim 1, wherein

said air pocket has a generally square cross-sectional shape.

5. A separator according to claim 1, wherein

said terminal ends include at least one conductive layer.

6. A separator according to claim 5, wherein

said conductive layer is disposed on an outer surface of each of said terminal ends.

7. A separator according to claim 5, wherein

said conductive layer is embedded in each of said terminal ends.

8. A separator according to claim 1, wherein

said body includes at least one region formed of foam material and at least one region formed of solid material.

9. A separator according to claim 1, wherein

at least one of said terminal ends includes a linear channel.

10. A separator according to claim 9, wherein

said linear channel extends through substantially the center of said terminal end.

11. A separator according to claim 9, wherein

said linear channel is disposed in an outer surface of said terminal end.

12. A separator according to claim 1, wherein

said segments form a cross web, thereby defining at least four quadrants in the communication cable.

13. A separator according to claim 12, wherein

said cross-web includes at least one region formed of a foam material and at least one region formed of a solid material.

14. A communication cable, comprising:

a jacket;

at least one twisted wire group supported by said jacket; and

a separator received in said jacket, said separator including,

a body having at least first and second segments adapted to define a plurality of quadrants in the communication cable, said at least first and second segments being substantially perpendicular to each other and defining a junction point of said at least first and second segments,

each of said at least first and second segments including a main portion and a terminal end remote from said junction point of said segments, and each of said terminal ends having a shape such that each of said terminal ends is wider than said main portions of said segments, and

at least one air pocket defined between said terminal ends of said at least first and second segments, said air pocket including a gap sized such that said air pocket is substantially enclosed,

whereby said at least one twisted wire group is prevented from entering said air pocket.

15. A communication cable according to claim 14, wherein

said plurality of segments form a cross web, thereby defining at least four quadrants in the communication cable, and each of quadrants supporting a twisted wire group.

16. A communication cable according to claim 14, wherein

said width of each of said terminal ends increases toward said junction point of said segments.

17. A communication cable according to claim 14, wherein

each of said terminal ends has a generally triangular cross-sectional shape.

18. A communication cable according to claim 14, wherein

said air pocket has a generally square cross-sectional shape.

19. A communication cable according to claim 14, further comprising

a plurality of air pockets, each of said air pockets including a gap;

and

each of said gaps have a width substantially smaller than the diameter of each of said wire groups thereby preventing said wire groups from entering said air pockets.

20. A communication cable according to claim 14, wherein

an angle between a line extending from the center of said at least one wire group to a point of contact between said wire group and one of said terminal ends and a line perpendicular to a central plan of said segment with said one terminal end is about 15 to 35 degrees.

21. A separator according to claim 14, wherein

said terminal ends include at least one conductive layer.

22. A separator according to claim 21, wherein

said conductive layer is disposed on an outer surface of each of said terminal ends.

23. A separator according to claim 21, wherein

said conductive layer is embedded in each of said terminal ends.

24. A communication cable according to claim 14, wherein

said twisted wire group is in direct contact with at least one of said terminal ends.

25. A separator according to claim 14, wherein

at least one of said terminal ends includes a linear channel.

26. A separator according to claim 25, wherein

said linear channel extends through substantially the center of said terminal end.

27. A separator according to claim 25, wherein

said linear channel is disposed in an outer surface of said terminal end.

28. A communication cable according to claim 14, wherein

said separator is formed of one or more melt processable materials.

29. A communication cable according to claim 14, wherein

said separator includes at least one non-processable material.

30. A communication cable according to claim 14, wherein

said separator includes at least one region formed of foam material and at least one region formed of solid material.

31. A communication cable according to claim 14, wherein

the tensile strength of each of said terminals ends is greater than the tensile strength of said main portions of said segments.

32. A communication cable according to claim 14, wherein

the linear strength of each of said terminal ends is greater than the linear strength of said main portions of said segments.

33. A communication cable according to claim 14, wherein

said air pocket includes an optical fiber.

34. A communication cable according to claim 14, wherein

no portion of said separator extends beyond the diameter of said wire group.
