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 hybrid cable comprising:
an outer jacket having a transverse cross-sectional profile that defines a major axis and a minor axis, the outer 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 outer jacket is elongated along the major axis, the outer jacket including a central opening;
an intermediate layer that lines the central opening, the intermediate layer defining a passage;
at least one optical fiber positioned within the passage, wherein the intermediate layer is positioned between the outer jacket and the at least one optical fiber;
first and second electrical conductors embedded in the outer jacket;
wherein the central opening is disposed between the first and second electrical conductors;
wherein the central opening defines a first cross-dimension and the first and second electrical conductors each define a second cross-dimension, the first cross-dimension being greater than the second cross-dimension; and
pre-defined tear locations being integrated with the outer jacket, the pre-defined tear locations being weakened to allow the pre-defined tear locations to be manually torn to provide a left portion, a right portion and a center portion, the left, right and center portions being positioned along the major axis with the center portion being disposed between the left and right portions, the left, right and center portions being fully insulated and protected by the outer jacket after the pre-defined tear locations have been torn;
wherein the outer 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.

2. The hybrid cable of claim 1 , wherein the first and second electrical conductors have a stranded construction.

3. The hybrid cable of claim 1 , wherein the intermediate layer is a tensile strength structure.

4. The hybrid cable of claim 3 , wherein the tensile strength structure includes aramid yarns.

5. The hybrid cable of claim 3 , wherein the tensile strength structure is anchored to structure to limit the transfer of tensile load to the at least one optical fiber.

6. The hybrid cable of claim 5 , wherein the structure is a fiber optic connector.

7. The hybrid cable of claim 3 , wherein the tensile strength structure includes a reinforcing tape.

8. The hybrid cable of claim 7 , wherein the reinforcing tape is bonded to the outer jacket and include aramid yarns.

9. The hybrid cable of claim 1 , wherein the first and second electrical conductors each include a 12-gauge stranded copper wire.

10. The hybrid cable of claim 1 , wherein the first and second electrical conductors each include a 16-gauge stranded copper wire.

11. The hybrid cable of claim 1 , wherein a plurality of optical fibers are positioned within the passage.

12. The hybrid cable of claim 11 , wherein the plurality of optical fibers are coated optical fibers having outer diameters less than 300 microns.

13. The hybrid cable of claim 1 , wherein the outer jacket is made from a material having a composition that includes at least one of the following materials: a low smoke zero halogen material, a polyvinyl chloride (PVC) material, a fluorinated ethylene polymer (FEP) material, and a material having a polyolefin formulation.

14. The hybrid cable of claim 1 , wherein the pre-defined tear locations include a left pre-defined tear location and a right pre-defined tear location, the left and right pre-defined tear locations being positioned on opposite sides of the central opening of the outer jacket.

15. The hybrid cable of claim 14 , wherein the left and right pre-defined tear locations each include an upper slit that extends downwardly from the top side, a lower slit that extends upwardly from the bottom side, and a non-slitted portion positioned between the upper and lower slits.

16. The hybrid cable of claim 14 , wherein left and right pre-defined tear locations each intersect the major axis of the hybrid cable at a location outwardly offset from the central opening such that the left and right pre-defined tear locations do not intersect the central opening when the left and right pre-defined tear locations are torn from the central portion of the outer jacket.

17. The hybrid cable of claim 14 , wherein the left and right pre-defined tear locations are uninterrupted and run continuously along a length of the hybrid cable.

18. A hybrid cable comprising:
an outer jacket having a transverse cross-sectional profile that defines a major axis and a minor axis, the outer 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 outer jacket is elongated along the major axis, the outer jacket including a central opening;
an intermediate layer that lines the central opening, the intermediate layer defining a passage;
at least one optical fiber positioned within the passage, wherein the intermediate layer is positioned between the outer jacket and the at least one optical fiber;
first and second electrical conductors embedded in the outer jacket, wherein the central opening is disposed between the first and second electrical conductors; and
pre-defined tear locations being integrated with the outer jacket, the pre-defined tear locations being weakened to allow the pre-defined tear locations to be manually torn to provide a left portion, a right portion and a center portion, the left, right and center portions being positioned along the major axis with the center portion being disposed between the left and right portions, the left, right and center portions being fully insulated and protected by the outer jacket after the pre-defined tear locations have been torn;
wherein the outer 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.
