Abstract

Assemblies and methods are provided for facilitating fiber optic patching. More particularly, the assemblies and methods generally involve mounting fiber optic patch ports arranged along a horizontal plane with respect to a tray. The tray is movably positioned within a cabinet enclosure, e.g., in a pivotal or translational (sliding) relationship, thereby providing easy access to the ports. The horizontal configuration advantageously increases fiber optic patching density within a cabinet structure while maintaining port accessibility.

Claims

1. A fiber optic patching assembly, comprising:

(a) a cabinet enclosure defining a receiving cavity;

(b) a patch tray defining a front side and movably positioned within the receiving cavity of the cabinet enclosure;

(c) a plurality of fiber optic ports mounted in a horizontal plane relative to the tray, each fiber optic port defining at least one port opening;

wherein the plurality of fiber optic ports are aligned in a plurality of horizontal rows in the horizontal plane, each horizontal row defines a vertical plane that is transversely aligned relative to the front side of the tray; and

;

wherein each port opening in a particular horizontal row is (i) oriented at an acute angle or perpendicular relative to the horizontal plane; and

(ii) aligned with the vertical plane defined by the horizontal row.

2. The assembly according to claim 1, wherein the plurality of fiber optic ports include one or more duplex ports.

3. The assembly according to claim 1, wherein the plurality of fiber optic ports include one or more quad structures.

4. The assembly according to claim 1, wherein the plurality of fiber optic ports are supported by at least one cassette shell mounted with respect to the patch tray.

5. The assembly according to claim 4, wherein the at least one cassette shell includes a pre-terminated backbone cable.

6. The assembly according to claim 5, wherein the backbone cable is detachably engaged with an adapter associated with the at least one cassette shell.

7. The assembly according to claim 1, wherein the plurality of fiber optic ports are arranged in one or more side-by-side pairs, and wherein each of the one or more side-by-side pairs includes a transmission port and a receiving port.

8. The assembly according to claim 7, wherein the each of the one or more side-by-side pairs is adapted to receive a duplex patch cord.

9. The assembly according to claim 1, wherein each of the plurality of fiber optic ports is angled toward the front of the patch tray.

10. The assembly according to claim 1, wherein the patch tray is either pivotally or translationally mounted with respect to the cabinet enclosure.

11. The assembly according to claim 10, wherein the patch tray includes one or more hinge flanges for pivotally mounting the patch tray with respect to the cabinet enclosure.

12. The assembly according to claim 10, wherein the cabinet enclosure includes one or more sliding tracks for facilitating translational motion of the patch tray relative to the cabinet enclosure.

13. The assembly according to claim 12, wherein the cabinet enclosure includes a top sliding track and a bottom sliding track, and wherein the top sliding track and the bottom sliding track facilitate tilting the patch tray upon withdrawal from within the cabinet enclosure.

14. The assembly according to claim 1, wherein the fiber optic ports are mounted relative to one of:

(i) a top face of the patch tray, (ii) a bottom face of the patch tray, and (iii) both the top and the bottom faces of the patch tray.

15. The assembly according to claim 1, wherein the patch tray may be tilted up or down upon withdrawal from within the cabinet enclosure.

16. The assembly according to claim 1, wherein the patch tray is accessible from one or more sides of the cabinet enclosure.

17. The assembly according to claim 1, wherein the patch tray further includes at least one component adapted to facilitate cord management selected from the group consisting of:

(i) a spool, (ii) cord management clips, and (iii) a combination thereof.

18. The assembly according to claim 1, further comprising a spool to facilitate cord management, wherein the patch tray is pivotally mounted with respect to the cabinet enclosure at a pivot point, and wherein the spool is positioned in close proximity of the pivot point.

19. The assembly according to claim 1, further comprising a locking mechanism associated with the cabinet enclosure for securing access to the patch tray.

20. The assembly according to claim 1, wherein the cabinet enclosure includes a top cover.

21. The assembly according to claim 1, wherein the height of the cabinet enclosure is selected so as to permit patching operations therewithin.

22. The assembly according to claim 1, wherein the cabinet enclosure includes at least one component for facilitating mounting relative to a cable management rack selected from the group consisting of:

(i) mounting brackets, (ii) cabinet bend limiting clips, and (iii) combinations thereof.

23. The assembly according to claim 1, wherein the plurality of fiber optic ports are mounted with respect to a mounting deck, and wherein the mounting deck is elevated over and secured to the patch tray by brackets.

24. A method for configuring fiber optic ports, comprising the steps of:

(a) mounting a plurality of fiber optic ports with respect to a tray in a horizontal plane, each fiber optic port defining at least one port opening and the plurality of fiber optic ports being aligned in a plurality of horizontal rows in the horizontal plane; and

(b) movably mounting the tray with respect to a cabinet enclosure, with the tray defining a front side; and

wherein each horizontal row defines a vertical plane that is transversely aligned relative to the front side of the tray; and

wherein each port opening in a particular horizontal row is (i) oriented at an acute angle or perpendicular relative to the horizontal plane; and

(ii) aligned with the vertical plane defined by the horizontal row.

25. The method according to claim 24, wherein the tray is either pivotally or translationally mounted with respect to the cabinet enclosure.
