Abstract

Claims (53)

1. A lashing assembly for lashing together fiber optic telecommunications cables, the lashing assembly comprising:

a first spool assembly, the first spool assembly comprising:

a first bobbin; and

a first twine, the first twine wrapped around the first bobbin such that as a first cable and a second cable are passed through a passage through the first bobbin, the first twine pays off from the first bobbin and wraps around the first and second cables in a clockwise helix around lengthwise axes of the first and second cables, the first and second cables being fiber optic telecommunications cables; and

a second spool assembly, the second spool assembly comprising:

a second bobbin; and

a second twine, the second twine wrapped around the second bobbin such that as the first and second cables are passed through the passage through the second bobbin, the second twine pays off from the second bobbin and wraps around the first and second cables in a counterclockwise helix around the lengthwise axes of the first and second cables.

2. The lashing assembly of claim 1 ,

wherein the first spool assembly comprises a tensioning cover that provides tension on the first twine such that the first twine is appropriately tightened around the first and second cables as the first and second cables pass through the passage through the first bobbin; and

wherein the second spool assembly comprises a tensioning cover that provides tension on the second twine such that the second twine is appropriately tightened around the first and second cables as the first and second cables pass through the passage through the second bobbin.

3. The lashing assembly of claim 2 , wherein the tensioning covers of the first and second spool assemblies are made of an elastic material.

4. The lashing assembly of claim 2 , wherein the first twine is wrapped in multiple layers around the first bobbin and the second twine is wrapped in multiple layers around the second bobbin.

5. The lashing assembly of claim 1 ,

wherein the first spool assembly comprises a first faceplate, the first faceplate attached to a cable exit end of the first bobbin, the first faceplate aligning the first and second cables in a compact geometric configuration as the first and second cables pass through the first bobbin;

wherein the second spool assembly comprises a second faceplate, the second faceplate attached to a cable exit end of the second bobbin, the second faceplate aligning the first and second cables in the compact geometric configuration as the first and second cables pass through the second bobbin.

6. The lashing assembly of claim 5 , wherein the first faceplate is removable from the first bobbin and the second faceplate is removable from the second bobbin.

7. The lashing assembly of claim 1 , wherein the lashing assembly further comprises a bracket suitable for mounting to a utility pole, wherein the first and second spool assemblies are supported by the bracket when the bracket is mounted to the utility pole.

8. The lashing assembly of claim 1 ,

wherein the first bobbin is removable from the first and second cables; and

wherein the second bobbin is removable from the first and second cables.

9. The lashing assembly of claim 1 , wherein the first and second bobbins remain stationary as the first and second cables are passed through the first and second bobbins.

10. The lashing assembly of claim 1 ,

wherein the first cable comprises multiple optical fibers surrounded by a jacket; and

wherein the second cable comprises multiple optical fibers surrounded by a jacket.

11. A method comprising:

passing a first cable and a second cable through a passage through a first bobbin of a first spool assembly, the first and second cables being fiber optic telecommunications cables, wherein as the first and second cables are passed through the first bobbin, a first twine pays off from the first bobbin and wraps around both the first and second cables in a clockwise helix around lengthwise axes of the first and second cables; and

passing the first and second cables through the passage through a second bobbin of a second spool assembly, wherein as the first and second cables are passed through the second bobbin, a second twine pays off from the second bobbin and wraps around both the first and second cables in a counterclockwise helix around the lengthwise axes of the first and second cables, thereby lashing together the first and second cables.

12. The method of claim 11 ,

wherein one end of the first cable is connected to a first drop terminal; and

wherein one end of the second cable is connected to a second drop terminal.

13. The method of claim 12 , wherein the method further comprises attaching the first and second cables to a fiber distribution hub after pulling the first and second cables through the first and second bobbins.

14. The method of claim 12 , prior to pulling the first and second cables through the first and second bobbins, installing the first drop terminal on a first utility pole and installing the second drop terminal on a second utility pole.

15. The method of claim 14 , wherein the first and second bobbins are attached to a bracket that is attached to the second utility pole.

16. The method of claim 11 ,

wherein the first twine is wound around the first bobbin;

wherein a first tensioning cover covers the first twine while the first twine is on the first bobbin, the first tensioning cover providing tension on the first twine such that the first twine is appropriately tightened around the first and second cables as the first and second cables are passed through the first bobbin;

wherein the second twine is wound around the second bobbin; and

wherein a second tensioning cover covers the second twine while the second twine is on the second bobbin, the second tensioning cover providing tension on the second twine such that the second twine is appropriately tightened around the first and second cables as the first and second cables are passed through the second bobbin.

17. The method of claim 11 ,

wherein the first bobbin is removable from the first and second cables; and

wherein the second bobbin is removable from the first and second cables.

18. The method of claim 11 , further comprising:

attaching a first faceplate to a cable exit end of the first bobbin, the first faceplate aligning the first and second cables in a compact geometric configuration as the first and second cables pass through the first bobbin;

attaching a second faceplate to a cable exit end of the second bobbin, the second faceplate aligning the first and second cables in the compact geometric configuration as the first and second cables pass through the second bobbin.

19. The method of claim 11 ,

wherein the first cable comprises multiple optical fibers surrounded by a jacket; and

wherein the second cable comprises multiple optical fibers surrounded by a jacket.

20. The method of claim 11 ,

wherein the method further comprises:

passing the first cable, the second cable, and a third cable through a third bobbin, wherein as the first, second, and third cables are passed through the third bobbin, a third twine pays off from the third bobbin in a clockwise direction, forming a clockwise helix around the first, second, and third cables; and

passing the first, second, and third cables through a fourth bobbin, wherein as the first, second, and third cables are passed through the fourth bobbin, a fourth twine pays off from the fourth bobbin in a counterclockwise direction, forming a counterclockwise helix around the first, second, and third cables, thereby lashing together the first, second, and third cables; and

wherein the first and second bobbins are part of a first lashing assembly attached to a utility pole and the third and fourth bobbins are part of a second lashing assembly attached to another utility pole;

wherein interior diameters of the third and fourth bobbins are greater than interior diameters of the first and second bobbins.
