Abstract

The present invention provides modular trays having cutout features that are configured to engage with a mounting feature of one or more removable rails. The removable rails may be removeably secured to a tray body in a plurality of positions to allow a user to install or uninstall rails to support different sized fiber optic modules. For example, a tray may support a twenty-four optical fiber module, two twelve optical fiber modules, or three eight optical fiber modules. Fiber optic enclosures housing the trays can be affixed to the outside of a fiber optic enclosure and allow for easy stacking and unstacking.

Claims

1. A tray to support fiber optic equipment, said tray comprising:

a tray body having a first side edge portion, a second side edge portion, a front side edge portion, a rear side edge portion and a middle portion, wherein said middle portion of said tray body has a plurality of cutout features;

wherein said first side edge portion is configured to be secured to a first rail;

wherein said second side edge portion is configured to be secured to a second rail; and

,

wherein said plurality of cutout features are configured to engage with a mounting feature of a third rail such that the third rail may be removably secured to the tray body in a plurality of positions.

2. The tray of claim 1, wherein said plurality of cutout features are arranged as a first set of at least two cutouts in the middle portion of said tray body.

3. The tray of claim 2, wherein said first set of at least two cutouts in the middle portion of said tray body is disposed in a line parallel to the first side edge portion.

4. The tray of claim 3, wherein said first set of at least two cutouts is disposed along a midline between the first side edge portion and the second side edge portion.

5. The tray of claim 4, further comprising a second set of cutout features disposed between the first side edge portion of the tray body and the first set of at least two cutouts disposed along said midline.

6. The tray of claim 5, wherein said second set of cutout features is arranged as a set of at least two cutouts in the middle portion of said tray body in a line parallel to the first side edge portion.

7. The tray of claim 5, further comprising a third set of cutout features disposed between the second side edge portion of the tray body and the first set of at least two cutouts disposed along said midline.

8. The tray of claim 7, wherein said third set of cutout features is arranged as a set of at least two cutouts in the middle portion of said tray body in a line parallel to the second side edge portion.

9. A system to support fiber optic equipment, said system comprising:

a tray body having a first side edge portion, a second side edge portion, a front side edge portion, a rear side edge portion and a middle portion, wherein said middle portion of said tray body has a first set of cutout features and a second set of cutout features;

a first rail secured to said first side edge portion;

a second rail secured to said second side edge portion; and

,

a third rail having a mounting feature configured to be removably secured to said first set of cutout features or said second set of cutout features.

10. The system of claim 9, wherein said third rail is not secured to said first set of cutout features or said second set of cutout features such that a twenty-four optical fiber module may be secured to said tray by said first rail and said second rail.

11. The system of claim 9, wherein said first set of cutout features is arranged as a set of at least two cutouts disposed in parallel to the first side edge portion of said tray and disposed along a midline between the first side edge portion and the second side edge portion.

12. The system of claim 11, wherein said third rail is removably secured to said first set of cutout features.

13. The system of claim 12, wherein a first twelve optical fiber module may be secured to said tray by said first rail and said third rail, and wherein a second twelve optical fiber module may be secured to said tray by said second rail and said third rail.

14. The system of claim 9, wherein said second set of cutout features is arranged as a set of at least two cutouts disposed in parallel to the first side edge portion of said tray and disposed between a midline between the first side edge portion and the second side edge portion and the first side edge portion of said tray.

15. The system of claim 14, further comprising a third set of cutout features arranged as a set of at least two cutouts disposed in parallel to the second side edge portion of said tray and disposed between said midline and the second side edge portion of said tray.

16. The system of claim 15, wherein said third rail is removably secured to said second set of cutout features.

17. The system of claim 15, wherein said third rail is removably secured to said third set of cutout features.

18. The system of claim 15, wherein said third rail is removably secured to said second set of cutout features and further comprising a fourth rail removably secured to said third set of cutout features.

19. The system of claim 18, wherein a first eight optical fiber module may be secured to said tray by said first rail and said third rail, a second eight optical fiber module may be secured to said tray by said third rail and said fourth rail, and a third eight optical fiber module may be secured to said tray by said fourth rail and said second rail.

20. The system of claim 9, further comprising an enclosure having a top portion, a bottom portion, a first side and a second side, wherein portions of said bottom portion of said enclosure are raised in parallel to said cutout features to facilitate a gap between the tray body and portions of the bottom portion of said enclosure that are not raised.

21. The system of claim 9, wherein said first side edge portion of said tray body is configured to mount to a first side edge portion of a second tray body and said second side edge portion of said tray body is configured to mount to a second side edge portion of a second tray body.
