Abstract

The present invention relates to telecommunications equipment racks including vertical cable guides, horizontal troughs, cross aisle panels and cross-connection modules for telecommunications equipment racks. The vertical cable guides define vertical cable channels for both network infrastructure and cross-connection cables. The structure defining the second cable channel is hingedly attached to the structure defining the first cable channel. The horizontal cable troughs include both upper and lower troughs. The upper cable trough defines two cableways for directing cross-connection and other cables, and provides access openings for cables to pass into and out of each cableway and between the two cableways. The lower cable trough defines a cableway and provides access openings for cables extending into and out of the cableway. Cable troughs attached to adjacently mounted equipment racks cooperate to form continuous horizontal cableways. The cross aisle panel includes movable cable guide structures to permit access to connectors mounted on the panel. The cross-connection modules provide multiple connector planes on the rear of the module to increase the number of circuits the module can support.

Claims

1. A cable trough structure for use with a telecommunications equipment rack wherein equipment is mounted in the rack and a cable extends from the equipment, the cable trough structure comprising:

a mounting side, a bottom extending generally perpendicular to the mounting side, a first outer wall a first distance from the mounting wall, the first outer wall extending upward from the bottom and a second outer wall a second distance from the mounting wall the second outer wall extending upward from the bottom;

a first cableway defined by the mounting wall, the bottom and the first outer wall;

a second cableway defined by the first outer wall, the bottom and the second outer wall;

wherein a cable passage opening is defined between the first cableway and the second cableway through the first outer wall.

2. The cable trough structure of claim 1, wherein an opening is defined in the second outer wall.

3. The cable trough structure of claim 1, wherein a cable access opening is defined in the bottom within the first cableway.

4. The cable trough structure of claim 1, wherein a cable exit is defined in the bottom within the second cableway.

5. The cable trough structure of claim 2, wherein the opening and the cable passage opening cooperate to provide external visibility to the first cableway.

6. The cable trough structure of claim 1, further comprising at least one infrastructure cable opening defined in the bottom within the first cableway.

7. The cable trough structure of claim 1, wherein the second distance is greater than the first distance.

8. The cable trough structure of claim 1, wherein the mounting side includes mounting openings.

9. A cable trough structure comprising:

a planar mounting side having a front and a rear, a bottom extending outwardly from the front of the mounting side, a first outer wall a first distance from the front of the mounting wall, the first outer wall extending generally parallel to the mounting side from the bottom and a second outer wall a second distance from the front of the mounting wall, the second outer wall extending from the bottom generally parallel to the mounting side and the first outer wall;

a first cableway defined by the mounting wall, the bottom and the first outer wall; and

a second cableway defined by the first outer wall, the bottom and the second outer wall;

wherein a cable passage opening is defined between the first cableway and the second cableway through the first outer wall.

10. The cable trough structure of claim 9, wherein an opening is defined in the second outer wall.

11. The cable trough structure of claim 9, wherein a cable access opening is defined in the bottom within the first cableway.

12. The cable trough structure of claim 9, wherein a cable access opening is defined in the bottom within the second cableway.

13. The cable trough structure of claim 10, wherein the opening and the cable passage opening cooperate to provide external visibility to the first cableway.
