Abstract

An apparatus and method for accessing and/or repairing a select subset of fibers in an ADSS fiber optic cable. The apparatus includes a housing extending from a first end to a second end. A first fiber optic splice tray is positioned within the housing closer to the first end than to the second end. A second fiber optic splice tray is positioned within the housing and spaced apart from the first splice tray. A tension member extends through the housing and includes a first mechanical connector near the first end and a second mechanical connector near the second end. The connectors provide an attachment location for deadends at either end for transferring tension from the undamaged portion of the ADSS fiber optic cable.

Claims (25)

1. An apparatus for accessing select fibers in an All-Dielectric Self-Supporting (ADSS) fiber optic cable, comprising:

a housing extending from a first end to a second end, wherein the housing is weather resistant when closed by a hinged lid that opens to permit access to an internal cavity of the housing;

a first fiber optic splice tray positioned within the housing closer to the first end than to the second end;

a second fiber optic splice tray positioned within the housing and spaced apart from the first splice tray and closer to the second end than to the first end;

a load-bearing member extending through the housing and including a first mechanical connector external to the housing near the first end and a second mechanical connector external to the housing near the second end, wherein at least one of the first mechanical connector and the second mechanical connector is adapted to connect to ADSS fiber optic cable.

2. The apparatus of claim 1 , wherein the housing has an axial length between the first end and the second that is at least six feet.

3. The apparatus of claim 2 , wherein the load-bearing member is a fiberglass rod.

4. The apparatus of claim 2 , wherein each mechanical connector is a closed loop that is attached to the load-bearing member by internal threading that corresponds to external threading present on at least a portion of the load-bearing member.

5. The apparatus of claim 1 , wherein the housing defines a first end compartment at the first end in which is the first fiber optic splice tray is positioned and a second end compartment at the second end in which the second fiber optic splice tray is positioned.

6. The apparatus of claim 5 , wherein the housing further defines a body portion connecting the first end compartment to the second end compartment.

7. The apparatus of claim 6 , wherein the body portion defines at least two different chambers that are each open to both the first end compartment and the second end compartment.

8. The apparatus of claim 7 , wherein the body portion defines a first chamber, a second chamber, and a third chamber, and wherein the tension member is positioned within the first chamber.

9. The apparatus of claim 8 , wherein the first splice tray is connected to the second splice tray by a plurality of repair fibers, and wherein the repair fibers are positioned within the second chamber.

10. The apparatus of claim 6 , wherein the housing defines a mounting hole in the body portion.

11. The apparatus of claim 10 , wherein the lid is detachable from the housing to permit access to an internal cavity of the housing.

12. An apparatus for accessing select fibers in an All-Dielectric Self-Supporting (ADSS) fiber optic cable, comprising:

a housing extending from a first end to a second end;

a first fiber optic splice tray positioned within the housing closer to the first end than to the second end;

a second fiber optic splice tray positioned within the housing and spaced apart from the first splice tray and closer to the second end than to the first end;

a load-bearing member extending through the housing and including a first mechanical connector external to the housing near the first end and a second mechanical connector external to the housing near the second end, wherein at least one of the first mechanical connector and the second mechanical connector is adapted to connect to ADSS fiber optic cable.

13. The apparatus of claim 12 , wherein the housing has an axial length between the first end and the second end that is at least six feet.

14. The apparatus of claim 13 , wherein the housing is weather resistant when closed by a hinged lid that opens to permit access to an internal cavity of the housing.

15. The apparatus of claim 12 , wherein the load-bearing member is a fiberglass rod.

16. The apparatus of claim 12 , wherein the first mechanical connector is a closed loop and the second mechanical connector is a closed loop.

17. The apparatus of claim 12 , wherein the first splice tray is connected to the second splice tray by a plurality of repair fibers.
