Abstract

The present description relates to an optical fiber interconnection tray. The interconnection tray has a base extending longitudinally from a first end to a second end, with a cable entrance at the first end of the tray. A first interconnection layer is disposed on the base, and a second interconnection layer is positioned over at least a portion of the first interconnection layer, wherein the second interconnection layer is disposed on a first repositionable mezzanine attached to the base at a plurality of locations.

First claim

The invention claimed is:

1. A optical fiber interconnection tray comprising:
a base extending longitudinally from a first end to a second end, wherein the base includes a cable entrance at the first end of the tray,
a first interconnection layer disposed on the base,
a second interconnection layer positioned over at least a portion of the first interconnection layer, wherein the second interconnection layer is disposed on a first repositionable mezzanine attached to the base at a plurality of locations between the first end and the second end of the base; and
a second mezzanine attached to the base of the tray, wherein the second mezzanine can be lifted from the base and nested on top of the first mezzanine to provide access to the first interconnection under the second mezzanine when the second mezzanine was attached to the base.

2. The interconnection tray of claim 1 , further comprising a plurality of optical component inserts disposed within a shallow channel formed in the base wherein each of the plurality of optical component inserts is configured to hold a first plurality of optical components.

3. The interconnection tray of claim 2 , wherein the first plurality of optical components can be selected from the optical splitters, mass fusion splices, single fusion splices, multifiber mechanical splices and mechanical splices.

4. The interconnection tray of claim 1 , wherein the mezzanine has a generally rectangular panel, two legs extending from a first edge of the rectangular panel and two legs extending from a second edge of the rectangular panel that is opposite the first edge.

5. The interconnection tray of claim 4 , wherein the mezzanine further includes a plurality of facing catches disposed along the first and second edges of the panel.

6. The interconnection tray of claim 5 , wherein an optical component insert is secured onto the panel of the repositionable mezzanine by the plurality of facing catches, wherein optical component insert is configured to hold a second plurality of optical components.

7. The interconnection tray of claim 6 , wherein the second plurality of optical components can be selected from the optical splitters, mass fusion splices, single fusion splices, multifiber mechanical splices and mechanical splices.

8. The interconnection tray of claim 1 , wherein the second interconnection layer positioned over the entire first interconnection layer.

9. The interconnection tray of claim 8 , wherein the first interconnection layer comprises a first plurality of optical component inserts disposed on the base of the interconnection tray, and wherein the second interconnection layer comprises a second plurality of optical component inserts, wherein each of the second plurality of optical inserts is disposed on a separate a repositionable mezzanine that is secured to the base of the interconnection tray over a corresponding one of first plurality of optical component inserts of the first interconnection layer.

10. The interconnection tray of claim 9 , wherein the first plurality of optical component inserts and the second plurality of optical component inserts are configured to hold fusion splices.

11. The interconnection tray of claim 9 , wherein the first plurality of optical component inserts and the second plurality of optical component inserts are configured to hold mechanical splices.

12. The interconnection tray of claim 1 , further comprising a first interconnection zone and a second interconnection zone.

13. The interconnection tray of claim 1 , further comprising a fiber routing channel between the first interconnection zone and the second interconnection zone.

14. The interconnection tray of claim 1 , further comprising a connection mechanism disposed on the first end of the base, wherein the connection mechanism is configured to rotatably connect the interconnection tray to at least a second interconnection tray.

15. The interconnection tray of claim 1 , wherein the base is wider at the first end of the base than at the second end of the base.

16. The interconnection tray of claim 1 , further comprising an auxiliary strain relief plate disposed in the cable entrance to accommodate additional optical fibers entering and exiting the tray.

17. A optical fiber interconnection tray comprising:
a base extending longitudinally from a first end to a second end, wherein the base includes a cable entrance at the first end of the tray;
a plurality of optical component inserts, each insert disposed on a repositionable mezzanine so that the optical component insert is spaced above the base of the interconnection tray;
a second mezzanine attached to the base of the tray, wherein the second mezzanine can be lifted from the base and nested on top of the first mezzanine to provide access to a slack storage region disposed under the second mezzanine when the second mezzanine was attached to the base; and
a slack storage region disposed between the optical component inserts and the base of the interconnection tray.
