Telecommunications chassis with slidable trays

1. A telecommunications system comprising:

a telecommunications chassis configured to slidably receive a telecommunications tray that supports telecommunications equipment, wherein the telecommunications chassis includes at least part of a slide assembly for receiving the telecommunications tray, the slide assembly comprising:

a tray rail mounted to the telecommunications chassis, the tray rail defining a rail sliding cavity flanked by a first detent adjacent a first end and a second detent adjacent a second end of the tray rail, the tray rail further comprising a first chassis mounting feature and a second chassis mounting feature, wherein the first and the second chassis mounting features are oriented with respect to each other such that, if two of the same tray rails are aligned and brought together in a juxtaposed relationship with the first and second chassis mounting features facing each other, the first and the second chassis mounting features can nest relative to each other so as to not increase the total width of the two tray rails.

2. The telecommunications system of claim 1 , wherein the telecommunications chassis is configured to receive a plurality of the telecommunications trays in a vertically stacked relationship.

3. The telecommunications system of claim 1 , wherein the telecommunications chassis is configured to receive at least two of the telecommunications trays in a side-by-side horizontally stacked relationship with two of the same tray rails mounted facing each other so as to capture a center wall of the chassis thereinbetween.

4. The telecommunications system of claim 1 , wherein the first and second chassis mounting features are defined by tabs protruding from a face of the tray rail.

5. The telecommunications system of claim 1 , wherein each of the first and second chassis mounting features is defined by a latch and an adjacent latch opening, wherein the orientation of the latch and the latch opening of the first chassis mounting feature is reversed with respect to the orientation of the latch and latch opening of the second chassis mounting feature.

6. The telecommunications system of claim 5 , wherein the latch defined by the first chassis mounting feature is configured to align with and fit within the latch opening defined by the second chassis mounting feature when two of the same tray rails are aligned and brought together in a juxtaposed relationship with the first and second chassis mounting features facing each other.

7. The telecommunications system of claim 1 , wherein the tray rail defines a stop feature configured for limiting further sliding movement of a telecommunications tray that has been mounted to the telecommunications chassis, wherein the stop feature is defined by a protrusion at least partially extending into the rail sliding cavity.

8. A telecommunications system comprising:

a telecommunications chassis defining a right wall, a left wall, and a center wall, the telecommunications chassis configured to slidably receive a pair of telecommunications trays mounted in a side-by-side horizontally stacked relationship to the telecommunications chassis, wherein the telecommunications chassis includes at least part of a slide assembly for receiving each of the telecommunications trays, the slide assembly comprising:

a tray rail configured for mounting to the telecommunications chassis, the tray rail defining a rail sliding cavity flanked by a first detent adjacent a first end and a second detent adjacent a second end of the tray rail, the tray rail further comprising a first chassis mounting feature and a second chassis mounting feature, wherein the first and the second chassis mounting features are oriented with respect to each other such that if two of the same tray rails are aligned and brought together in a juxtaposed relationship with the first and second chassis mounting features facing each other, the first and the second chassis mounting features can nest relative to each other so as to not increase the total width of the two tray rails, wherein a tray rail of the slide assembly is mounted to each of the right and left walls of the telecommunications chassis and two of the same tray rails are mounted facing each other to the center wall of the telecommunications chassis so as to capture the center wall thereinbetween.

9. The telecommunications system of claim 8 , wherein the first and second chassis mounting features are defined by tabs protruding from a face of the tray rail.

10. The telecommunications system of claim 8 , wherein each of the first and second chassis mounting features is defined by a latch and an adjacent latch opening, wherein the orientation of the latch and the latch opening of the first chassis mounting feature is reversed with respect to the orientation of the latch and latch opening of the second chassis mounting feature.

11. The telecommunications system of claim 10 , wherein the latch defined by the first chassis mounting feature is configured to align with and fit within the latch opening defined by the second chassis mounting feature when two of the same tray rails are aligned and brought together in a juxtaposed relationship with the first and second chassis mounting features facing each other.

12. The telecommunications system of claim 8 , wherein the tray rail defines a stop feature configured for limiting further sliding movement of the telecommunications trays that have been mounted to the telecommunications chassis, wherein the stop feature is defined by a protrusion at least partially extending into the rail sliding cavity.
