Abstract

A fiber optic apparatus having a fiber optic equipment tray and an extension adapted to receive, organize and manage fiber optic cables routed to the fiber optic equipment tray is disclosed. The fiber optic equipment tray has a front, a rear, a base, and at least one extension rail. The extension movably attaches to the fiber optic equipment tray at the extension rail and, thereby, slidably extends from and retracts toward the rear of the fiber optic equipment tray. The extension comprises a shelf and a cable management tray hingedly attached to the shelf. The shelf moves over the base when the extension extends from and retracts toward the fiber optic equipment tray. The cable management tray is in planer alignment with the fiber optic equipment tray when the extension is retracted, and allowed to pivot downwardly when the extension is extended. At least one furcation plug tray attaches to the cable management tray. The at least one furcation plug tray adapted to mount at least one furcation plug to which fiber optic cables may be connected.

Claims

1. A fiber optic apparatus, comprising:

a fiber optic equipment tray having a front and a rear; and

an extension movably engaged with the fiber optic equipment tray, wherein the extension extends from and retracts toward the rear of the fiber optic equipment tray, and wherein the extension is adapted to receive fiber optic cables routed to the fiber optic equipment tray.

2. The fiber optic apparatus of claim 1, further comprising at least one extension rail attached to the fiber optic equipment tray, wherein the extension extends from and retracts toward the fiber optic equipment tray using the at least one extension rail.

3. The fiber optic apparatus of claim 2, wherein the at least one extension rail comprises a slidable rail attached to the extension, and wherein the extension slidably extends from and retracts toward the fiber optic equipment tray.

4. The fiber optic apparatus of claim 1, wherein the extension comprises a shelf positioned over a base at the rear of the fiber optic equipment tray, and wherein the shelf moves over the base when the extension extends from and retracts toward the fiber optic equipment tray.

5. The fiber optic apparatus of claim 1, wherein the extension comprises a cable management tray, and wherein the cable management tray pivots downwardly.

6. The fiber optic apparatus of claim 5, further comprising at least one furcation plug tray attached to the cable management tray, wherein the at least one furcation plug tray is adapted for mounting one or more furcation plugs.

7. The fiber optic apparatus of claim 5, wherein the extension comprises a shelf, and wherein the cable management tray is hingedly attached to the shelf.

8. The fiber optic apparatus of claim 5, wherein the cable management tray is releasably retained in planar alignment with the fiber optic equipment tray when the extension is retracted, and wherein the cable management tray pivots downwardly from planar alignment with the fiber optic equipment tray when the extension is extended.

9. The fiber optic apparatus of claim 8, further comprising at least one plunger, wherein the at least one plunger positions into a slot to releasably retain the cable management tray in planar alignment with the fiber optic equipment tray when the extension is retracted.

10. The fiber optic apparatus of claim 5, further comprising a pivot stop, wherein the pivot stop limits the amount of downward pivot of the cable management tray.

11. The fiber optic apparatus of claim 10, wherein the pivot stop limits the amount of downward pivot of the cable management tray to about 20°

.

12. The fiber optic apparatus of claim 1, further comprising a locking mechanism, wherein the locking mechanism releasably locks the extension to the fiber optic equipment tray when the extension is retracted.

13. The fiber optic apparatus of claim 12, wherein the locking mechanism comprises at least one snap pem, wherein the at least one snap pem inserts into a locking hole to releasably lock the extension to the fiber optic equipment tray when the extension is retracted.

14. A fiber optic apparatus, comprising:

a fiber optic equipment tray having a front and a rear;

at least one extension rail comprising a slidable inner rail and a stationary outer rail, wherein the extension rail attaches to the fiber optic equipment tray via the stationary outer rail; and

an extension comprising at least one side support, wherein the extension attaches to the slidable inner rail of the least one extension rail at the at least one side support, wherein the extension slidably extends from and retracts toward the rear of the fiber optic equipment tray using the slidable inner rail, and wherein the extension is adapted to receive fiber optic cables routed to the fiber optic equipment tray.

15. The fiber optic apparatus of claim 14, wherein the extension comprises a shelf positioned over a base at the rear of the fiber optic equipment tray and a cable management tray hingedly attached to the shelf, and wherein the shelf moves over the base when the extension extends from and retract toward the fiber optic equipment tray.

16. The fiber optic apparatus of claim 15, wherein the shelf and the cable management tray are in planer alignment with the fiber optic equipment tray when the extension is retracted, and wherein the cable management tray is allowed to pivot downwardly when the extension is extended.

17. The fiber optic apparatus of claim 16, wherein cable management tray is allowed to pivot downwardly at least about 20°

measured from the planar alignment of the fiber optic equipment tray.

18. A method of managing fiber optic cables received by a fiber optic apparatus, comprising the steps of:

providing a fiber optic equipment tray having a front and a rear;

providing an extension movably attached to the fiber optic equipment tray, wherein the extension extends from and retracts toward the rear of the fiber optic equipment tray;

extending the extension to receive one or more fiber optic cable routed to the fiber optic equipment tray; and

receiving the one or more fiber optic cables by the extension.

19. The method of claim 18, wherein the extension comprises a hingedly attached cable management tray, and further comprising the step of pivoting the cable management tray when the extension is extended.

20. The method of claim 19, wherein the cable management tray comprises at least one furcation plug tray adapted to mount at least one furcation plug.

21. The method of claim 20, further comprising the step of connecting the one or more fiber optic cables to at least one furcation plug mounted in the fiber optic equipment tray.

22. The method of claim 21, further comprising the step of routing at least one optical fiber from the at least one furcation plug to at least one adapter and/or module mounted in the fiber optic equipment tray.

23. The method of claim 19, further comprising the steps of,

pivoting the cable management tray upwardly to be in planar alignment with the fiber optic equipment tray;

and

retracting the extension toward the fiber optic equipment tray.

24. The method of claim 23, further comprising the steps of,

releasably retaining the cable management in planar alignment with the fiber optic equipment tray;

and

releasably locking the extension to the fiber optic equipment tray.
