Abstract

The present invention relates to a slack storage tray for managing slack associated with fiber terminations in a distribution cabinet. The storage tray includes a base defining a cable pathway for storing multiple loops of a cable. A hinged cover further defines a cable pathway for managing the cable.

Claims

1. A cable storage system comprising:

a fixture;

a plurality of slack storage trays mounted to the fixture, each slack storage tray including a bottom wall, an outer wall extending from the bottom wall, and an inner wall defining a cable path for holding multiple loops of cable positioned around an axis perpendicular to the bottom wall; and

a cable termination area arranged adjacent the slack storage trays, the cable termination area including a plurality of horizontal rows of adapters, each adapter defining a connection axis for receiving a connecter, the connection axes of the adapters of each horizontal row arranged in a horizontal plane parallel to the bottom walls of the slack storage trays, wherein each horizontal row of adapters is slidable along the horizontal plane relative to the slack storage trays.

2. The cable storage system of claim 1, further comprising a cable manager for directing in a vertical direction cables extending from the rows of adapters.

3. The cable storage system of claim 2, wherein the adapters are mounted to a side wall of the fixture, and wherein the slack storage trays are mounted to a back wall of the fixture, wherein the side wall and the back wall are generally perpendicular to one another.

4. The cable storage system of claim 3, further comprising a plurality of splitter modules wherein cables extending from the splitter modules are managed by the cable manager and extend to the rows of adapters.

5. The cable storage system of claim 1, further comprising a plurality of cables, each cable extending from a first end to a second end terminated at a connector, the first end of each cable being stored within the cable path of one of the slack storage trays, the connector of each cable being inserted into one of the adapters of one of the horizontal rows of adapters.

6. The cable storage system of claim 5, wherein the inner wall of each slack storage tray is dimensioned to prevent any cables stored within the cable path of the slack storage tray from tightening beyond a minimum bend radius when one of the horizontal rows of adapters is slid relative to the slack storage tray.

7. The cable storage system of claim 5, wherein the outer wall of each slack storage tray is configured to receive and retain slack length of any cable stored within the cable path of the slack storage tray when one of the horizontal rows of adapters is slid relative to the slack storage tray.

8. The cable storage system of claim 5, wherein each of the slack storage trays is associated with at least one of the horizontal rows of adapters, the connector of each cable stored in each slack storage tray being inserted into one of the adapters of the associated horizontal row of adapters.

9. The cable storage system of claim 1, wherein each of the slack storage trays is associated with two horizontal rows of adapters.

10. The cable storage system of claim 1, wherein each horizontal row of adapters includes six adapters.

11. The cable storage system of claim 1, wherein each of the slack storage trays include a plurality of cable retention tabs extending from at least one of the outer and inner walls.

12. The cable storage system of claim 1, wherein each of the slack storage trays further comprises a base and a cover hinged to the base, the base including the bottom wall, the inner wall, and the outer wall.

13. The cable storage system of claim 12, wherein the cover of each slack storage tray comprises a bottom wall;

an upstanding outer wall extending from the bottom wall of the cover;

an upstanding inner wall disposed within the outer wall of the cover and extending upwardly from the bottom wall of the cover.

14. The cable storage system of claim 13, wherein the cover of each slack storage tray further comprises a cable pass-through location defined through the bottom wall of the cover.

15. The cable storage system of claim 13, wherein the cover of each slack storage tray further comprises a cable exit location for cables exiting from the cable storage tray.

16. The cable storage system of claim 15, wherein the cable exit location is defined in the upstanding outer wall.

17. The cable storage system of claim 15, wherein the cable exit location extends from a first side of the cable storage tray to a second side of the cable storage tray to define an open front of the cover.
