Abstract

A fiber management tray is described including a releasable connection interface. The tray can include a base defining at least one component mounting location having a structure for mounting optical components. The structure may define a first side and an opposite second side. The structure may also define a first retention opening and a second retention opening that extend through the structure from the first side to the second side. The first retention opening can include a T-shaped slot having a first portion and a second portion. The first portion of the T-shaped slot may have a larger cross-dimension than a cross-dimension of the second portion of the T-shaped slot. The second retention opening may have a first portion in which a flexible cantilever is positioned and a second portion. The second portion of the second retention opening may have a smaller cross-dimension than a cross-dimension of the first portion of the second retention opening. The flexible cantilever can include a release member that projects outwardly in a first direction from the first side of the structure.

First claim

What is claimed is:

1. An arrangement including a releasable connection interface, the arrangement comprising:
a structure defining a first side and an opposite second side, the structure also defining a first retention opening and a second retention opening that extend through the structure from the first side to the second side, the first retention opening including a T-shaped slot having a first portion and a second portion, the first portion of the T-shaped slot having a larger cross-dimension than a cross-dimension of the second portion of the T-shaped slot, the second retention opening having a first portion in which a flexible cantilever is positioned and a second portion, the second portion of the second retention opening having a smaller cross-dimension than a cross-dimension of the first portion of the second retention opening, the flexible cantilever including a release member that projects outwardly in a first direction from the first side of the structure; and
a protective holder that attaches to the first side of the structure, the protective holder including a main holder body that is elongated along a holder body axis, the main holder body defining a receptacle for receiving a fiber optic component, the protective holder including first and second retention features that project from the main holder body, the first and second retention features being configured to be respectively received within the first and second retention openings, the protective holder being moveable relative to the structure along an axial orientation defined by the holder body axis between first and second first holder positions, the axial orientation being perpendicular relative to the first direction, the first retention feature being positioned in the first portion of the first retention opening and the second retention feature being positioned within the first portion of the second retention opening when the fiber optic component holder is in the first holder position, the first retention feature being positioned in the second portion of the first retention opening and the second retention feature being positioned within the second portion of the second retention opening when the fiber optic component holder is in the first holder position, the protective holder being removable from the structure in the first direction when the protective holder is in the first holder position, and the protective holder not being removable from the structure in the first direction when the protective holder is in the second holder position; and
the flexible cantilever being movable between a non-flexed position and a flexed position, the flexible cantilever moving in a second direction opposite from the first direction when moving from the non-flexed position to the flexed position, the flexible cantilever being configured to prevent the protective holder from being moved from the second holder position to the first holder position when in the non-flexed position, the flexible cantilever being configured to allow the protective holder to be moved from the second holder position to the first holder position when in the flexed position, and the release member being configured to be manually pressed from the first side of the structure to cause the flexible cantilever to be manually moved from the non-flexed position to the flexed position while the protective holder is in the second holder position thereby allowing the protective holder to be moved from the second holder position to the first holder position and then released from the structure.

2. The arrangement of claim 1 , wherein the structure includes a fiber management tray.

3. The arrangement of claim 1 , wherein the fiber optic component is positioned within the receptacle of the protective holder, and wherein the fiber optic component is selected from the group consisting of a splice, a passive optical power splitter, and a wavelength division multiplexer.

4. The arrangement of claim 1 , wherein the release member is one of two release members on the flexible cantilever, and wherein protective holder mounts between the release members when in the first and second holder positions.

5. The arrangement of claim 1 , wherein the first and second retention features have profiles that mechanically interfere with the structure when the protective holder is in the second holder position such that the protective holder is prevented from being removed from the structure in the first direction.

6. The arrangement of claim 5 , wherein the first and second retention features have dovetail cross-sectional profiles that mate with corresponding dovetail cross-section profiles defined by the second portions of the first and second openings.

7. The arrangement of claim 1 , further comprising a keying mechanism for mounting the protective holder to the structure in only one way.

8. A fiber management tray including a releasable connection interface, the tray comprising:
a base defining at least one component mounting location having a structure for mounting optical components, the structure defining a first side and an opposite second side, the structure also defining a first retention opening and a second retention opening that extend through the structure from the first side to the second side, the first retention opening including a T-shaped slot having a first portion and a second portion, the first portion of the T-shaped slot having a larger cross-dimension than a cross-dimension of the second portion of the T-shaped slot, the second retention opening having a first portion in which a flexible cantilever is positioned and a second portion, the second portion of the second retention opening having a smaller cross-dimension than a cross-dimension of the first portion of the second retention opening, the flexible cantilever including a release member that projects outwardly in a first direction from the first side of the structure.

9. The fiber management tray of claim 8 , further comprising an optical component holder for holding an optical component, wherein the optical component holder attaches to the first side of the structure.

10. The fiber management tray of claim 9 , wherein the optical component is selected from the group consisting of a splice, a passive optical power splitter, and a wavelength division multiplexer.

11. The fiber management tray of claim 8 , wherein the tray is formed of a molded plastic material.

12. The fiber management tray of claim 8 , wherein the release member is one of two release members on the flexible cantilever.

13. The fiber management tray of claim 9 , wherein the release member is one of two release members on the flexible cantilever, and the optical component holder mounts between the release members.

14. The fiber management tray of claim 9 , further comprising a keying mechanism for mounting the optical component holder to the structure in only one way.

15. The fiber management tray of claim 9 , wherein the optical component holder includes first and second retention features that project from a main body, the first and second retention features being configured to be respectively received within the first and second retention openings of the structure.

16. The fiber management tray of claim 15 , wherein the first and second retention features have dovetail cross-sectional profiles that mate with corresponding dovetail cross-section profiles defined by the second portions of the first and second retention openings.
