Abstract

A telecommunications housing includes a plurality of outer walls defining a housing interior volume and an exit. A plurality of adapters is disposed on an interior panel for connection to connectors of fiber optic cables. At least one radius guide is mounted in the interior volume and has a cable guide portion configured to receive portions of the fiber optic cables and guide the fiber optic cables toward the exit without violating a predetermined minimum fiber optic bend radius. An external guide member may also be located on the outside the housing adjacent the exit. The external guide member has a cable guide portion configured to receive portions of the fiber optic cables and guide the fiber optic cables away from the exit without violating a predetermined minimum fiber optic bend radius.

Claims

1. A telecommunications housing, comprising:

a plurality of outer walls, the outer walls defining a housing interior volume and an exit therefrom;

an interior panel disposed within the housing interior volume;

a plurality of adapters disposed on the interior panel for connection to connectors of fiber optic cables; and

a radius guide mounted within the housing interior volume, the radius guide having a cable guide portion configured to receive portions of the fiber optic cables spaced from the adapters and further configured to guide the fiber optic cables in a direction of the exit without violating a predetermined minimum fiber optic bend radius;

wherein central axes of the adapters extend toward the radius guide, and wherein the fiber optic cables are angled toward the radius guide when attached to the adapter.

2. The telecommunications housing as in claim 1, wherein the outer walls include a first wall, the interior panel being substantially perpendicular to the first wall, and further comprising a support plate located within the interior volume, the support plate being mounted at a non-orthogonal angle relative to the first wall and the interior panel, the radius guide being mounted to the support plate.

3. The telecommunications housing as in claim 2, wherein the outer walls include a second wall perpendicular to the first wall, and the exit comprises an opening extending though the second wall.

4. The telecommunications housing as in claim 1, wherein the adapters are formed in a column along the interior panel extending between a first end and a second end, the radius guide being located adjacent the second end of the column.

5. The telecommunications housing as in claim 4, wherein the adapters are attached to the interior panel so that the central axes extend outward non-orthogonally from the interior panel.

6. The telecommunications housing as in claim 1, wherein the central axes of the adapters are angled at up to about 30 degrees relative to the interior wall.

7. The telecommunications housing as in claim 1, wherein the cable guide portions have a curved configuration with a radius of curvature not less than the predetermined minimum fiber optic bend radius.

8. The telecommunications housing as in claim 7, wherein the predetermined minimum fiber optic bend radius is about ¼

inch to about 1.5 inches.

9. The telecommunications housing as in claim 1, wherein the adapters are formed in a plurality of columns along the interior panel, the columns extending between a first end and a second end, and further including a plurality of the radius guides, the radius guides being located adjacent the second end of a respective one of the columns.

10. The telecommunications housing as in claim 9, wherein the outer walls include a second wall perpendicular to the first wall and a third wall perpendicular to the first wall, the second and third walls being disposed at opposite sides of the housing and each including an exit therein, wherein the radius guides are located so as to guide some of the fiber optic cables toward the exit in the second wall and others of the fiber optic cables toward the exit in the third wall.

11. The telecommunications housing as in claim 1, further including an external guide member located on an outside surface of one of the outer walls adjacent the exit, the external guide member having a cable guide portion configured to receive portions of the fiber optic cables and guide the fiber optic cables away from the exit without violating a predetermined minimum fiber optic bend radius.

12. A telecommunications housing comprising:

a plurality of outer walls, the outer walls defining a housing interior volume, the outer walls including a first wall, a second wall substantially perpendicular to the first wall, and an exit extending through the second wall;

an interior panel disposed within the housing interior volume;

a plurality of adapters disposed on the interior panel for connection to connectors of fiber optic cables, the adapters being formed in a plurality of columns along the interior panel, the columns extending between a first end and a second end;

a support plate mounted within the housing interior volume at an angle to the first and second walls and the interior panel; and

a plurality of radius guides mounted to the support plate, the radius guides being located adjacent the second end of a respective one of the columns, the radius guides having a cable guide portion configured to receive portions of the fiber optic cables in the respective column and guide the fiber optic cables toward the exit without violating a predetermined minimum fiber optic bend radius.

13. The telecommunications housing as in claim 12, wherein the adapters have a central aids, the adapters being attached to the interior panel so That the central axes extend outward non-orthogonally from the interior panel.

14. The telecommunications housing as in claim 13, wherein the central axes of the adapters extend toward the radius guide, wherein the fiber optic cables are angled toward the radius guide when attached to the adapter.

15. The telecommunications housing as in claim 14, wherein the central axes of the adapters axe angled at up to about 30 degrees relative to the interior wall.

16. The telecommunications housing as in claim 12, wherein the cable guide portions have a curved configuration with a radius of curvature not less than the predetermined minimum fiber optic bend radius.

17. The telecommunications housing as in claim 16, wherein the predetermined minimum fiber optic bend radius is about ¼

inch to about 1.5 inches.

18. The telecommunications housing as in claim 12, wherein the outer walls include a third wall perpendicular to the first wall, the second and third walls being disposed at opposite sides of the housing and including an exit therein, wherein the radius guides are located so as to guide some of the fiber optic cables toward the exit in the second wall and others of the fiber optic cables toward the exit in the third wall.

19. The telecommunications housing as in claim 12, further including an external guide member located on an outside surface of one of the outer walls adjacent the exit, the external guide member having a cable guide portion configured to receive portions of the fiber optic cables and guide the fiber optic cables away from the exit without violating a predetermined minimum fiber optic bend radius.

20. A telecommunications housing, comprising:

a plurality of outer walls, the outer walls defining a housing interior volume and an exit;

an interior panel disposed within the housing interior volume;

a plurality of adapters disposed on the interior panel for connection to connectors of fiber optic cables;

a plurality of radius guides mounted within the housing interior volume, the radius guides having a cable guide portion configured to receive first portions of the fiber optic cables spaced from the adapters and guide The fiber optic cables toward the exit without violating a predetermined minimum fiber optic bend radius; and
