Abstract

The present disclosure relates to a hybrid cable having a jacket with a central portion positioned between left and right portions. The central portion contains at least one optical fiber and the left and right portions contain electrical conductors. The left and right portions can be manually torn from the central portion.

First claim

What is claimed is:

1. A cable comprising:
a cable jacket including a first portion surrounding a first transmission member and a second portion surrounding a second transmission member;
the first and second portions of the cable jacket being connected by a pre-defined peelable interface that allows the first and second portions of the cable jacket to be manually peeled apart while maintaining full coverage of the first transmission member by the first portion and full coverage of the second transmission member by the second portion, the pre-defined peelable interface being integrated with the cable jacket;
wherein the pre-defined peelable interface is defined by an upper slit that extends downwardly from a top side of the cable jacket and a lower slit that extends upwardly from a bottom side of the cable jacket;
wherein when the upper and lower slits are formed, material of the cable jacket is at least partially molten such that opposing slit defining surfaces of the upper and lower slits are partially bonded back together to form a weakened tear location in the cable jacket; and
wherein a solid, non-slitted portion is positioned between the upper and lower slits.

2. The cable of claim 1 , wherein the upper and lower slits are closed pre-formed slits.

3. The cable of claim 2 , wherein the pre-formed slits are uninterrupted and run continuously along a length of the cable.

4. The cable of claim 1 , wherein the cable jacket has a smooth outer surface free of dents and/or notches.

5. The cable of claim 1 , wherein at least one of the first and second transmission members includes an electrical conductor.

6. The cable of claim 5 , wherein the electrical conductor is solid metal or braided metal.

7. The cable of claim 6 , wherein the electrical conductor is solid copper or braided copper.

8. The cable of claim 1 , wherein at least one of the first and second transmission members includes an optical fiber.

9. The cable of claim 1 , wherein the cable jacket further includes a third portion connected by another pre-defined peelable interface.

10. The cable of claim 9 , wherein the third portion surrounds at least one of an optical fiber and an electrical conductor.

11. A cable comprising:
a cable jacket including a first portion surrounding a first transmission member, a second portion surrounding a second transmission member, and a central portion surrounding a central transmission member, the central portion being positioned between the first and second portions;
the first portion of the cable jacket being connected to the central portion by a first pre-defined peelable interface and the second portion of the cable jacket being connected to the central portion by a second pre-defined peelable interface, the first and second pre-defined peelable interfaces allowing the first and second portions of the cable jacket to be manually peeled apart while maintaining full coverage of the first transmission member by the first portion, full coverage of the second transmission member by the second portion, and full coverage of the central transmission member by the central portion, the first and second pre-defined peelable interfaces being integrated with the cable jacket;
the cable jacket having a transverse cross-sectional profile that defines a major axis and a minor axis, the cable jacket having a height measured along the minor axis and a width measured along the major axis, the width being greater than the height such that the transverse cross-sectional profile of the cable jacket is elongated along the major axis;
wherein the cable jacket includes opposite major sides that extend along the major axis, wherein the opposite major sides are generally flat and generally parallel to one another, the opposite major sides each having a constant thickness;
wherein the first and second pre-defined peelable interfaces are each defined by an upper slit that extends downwardly from a top side of the cable jacket and a lower slit that extends upwardly from a bottom side of the cable jacket, the top and bottom sides being the opposite major sides of the cable jacket;
wherein when the upper and lower slits are formed, material of the cable jacket is at least partially molten such that opposing slit defining surfaces of the upper and lower slits are partially bonded back together to form a weakened tear location in the cable jacket; and
wherein a solid, non-slitted portion is positioned between the upper and lower slits.

12. The cable of claim 11 , wherein the upper and lower slits are closed pre-formed slits.

13. The cable of claim 12 , wherein the pre-formed slits are uninterrupted and run continuously along a length of the cable.

14. The cable of claim 11 , wherein the cable jacket has a smooth outer surface free of dents and/or notches.

15. The cable of claim 11 , wherein at least one of the first and second transmission members includes an electrical conductor.

16. The cable of claim 15 , wherein the electrical conductor includes a 12-gauge stranded copper wire.

17. The cable of claim 11 , wherein the central transmission member includes at least one of an optical fiber and an electrical conductor.

18. The cable of claim 11 , wherein at least one of the first and second transmission members includes an optical fiber.

19. The cable of claim 18 , wherein the optical fiber is a coated optical fiber that has an outer diameter less than 300 microns.

20. The cable of claim 11 , wherein the first and second pre-defined peelable interfaces intersect the major axis of the cable at a location outwardly offset from the central portion such that the first and second pre-defined peelable interfaces do not intersect the central portion when the first and second portions are torn from the central portion of the cable jacket.
