Abstract

An array cable includes radius guides at a tap point of the cable to take up slack for loose fibers at the tap point. The tap point is enclosed in a flexible enclosure that allows the assembly to be pulled through constricted space such as air handling spaces.

Claims

1. A cable assembly, comprising:

an array cable having a plurality of electrical conductors and a plurality of optical conductors, the array cable having a tap point;

at least one radius guide at the tap point, the at least one radius guide having surface arranged to accommodate at least one optical fiber wrapped at least partially therearound;

at least one optical connection at the tap point;

at least one electrical connection at the tap point; and

an enclosure at least partially surrounding the tap point.

2. The cable assembly of claim 1, further comprising at least one tether extending away from the tap point, the tether having at least one tether optical conductor and at least one tether electrical conductor, the at least one tether optical conductor being connected to one of the optical conductors of the array cable at at least one of the optical connections, and the at least one tether optical fiber being at least partially wrapped around the at least one radius guide.

3. The cable assembly of claim 2, wherein the at least one tether electrical conductor is connected to one of the electrical connectors of the array cable at at least one of the electrical connections.

4. The cable assembly of claim 3, wherein the at least one radius guide is translatable along the array cable.

5. The cable assembly of claim 4, wherein the at least one optical connection is located at an adapter.

6. The cable assembly of claim 5, wherein the adapter is translatable along the cable.

7. The cable assembly of claim 5, wherein the at least one electrical connection is located at the adapter.

8. The cable assembly of claim 4, further comprising a furcation clip mounted on the array cable at the tap point and spaced from the at least one radius guide, the tether being mounted to the furcation clip.

9. The cable assembly of claim 4, wherein the at least one tether electrical conductor contacts and is at least partially wrapped around the at least one radius guide.

10. The cable assembly of claim 4, wherein the at least one radius guide is mounted to the array cable.

11. The cable assembly of claim 4, wherein the at least one radius guide comprises a first radius guide at a first location on the array cable and a second radius guide at a second location on the array cable.

12. The cable assembly of claim 11, wherein the first radius guide and the second radius guide are located on opposite sides of the cable.

13. The cable assembly of claim 4, wherein the enclosure is a flexible pouch.

14. The cable assembly of claim 1, wherein at least one optical conductor contacts and is at least partially wrapped around the at least one radius guide.

15. The cable assembly of claim 1, further comprising an adapter holder mounted to the array cable, wherein the at least one radius guide is mounted to the adapter holder.

16. The cable assembly of claim 15, wherein the at least one optical connection is located at the adapter holder.

17. The cable assembly of claim 1, wherein at least one radius guide comprises a polymer plate with curved radius guides formed thereon.

18. A method of connecting a remote device to an array cable assembly, the method comprising:

providing an array cable assembly comprising;

an array cable having a plurality of electrical conductors and a plurality of optical conductors, the array cable having a tap point;

at least one radius guide at the tap point;

at least one optical connection at the tap point; and

at least one electrical connection at the tap point;

looping at least one remote device optical conductor that is in optical communication with the remote device around the at least one radius guide;

translating the radius guide to take up slack in the at least one remote device optical conductor.

19. The method of claim 18, further comprising optically coupling the remote device to the array cable at the at least one optical connection.

20. The method of claim 19, further comprising:

electrically coupling the remote device to the array cable at the at least one electrical connection; and

enclosing the tap point in a flexible enclosure.
