Abstract

A fiber distribution hub includes a cabinet; a termination region positioned within the interior of the cabinet; at least one termination module mounted in at least one opening defined at the termination region; fiber optic connectors coupled to termination adapters of the termination module; intermediate fibers extending rearwardly of the fiber optic connectors; and a multi-fiber connector terminating the intermediate fibers. The termination module includes a housing enclosing the termination adapters. One or more termination modules can be incrementally added to the fiber distribution hub.

Claims

1. A fiber distribution hub adapted to provide an interface between an incoming fiber and a plurality of outgoing fibers, the fiber distribution hub comprising:

a cabinet having a front and a rear, the cabinet including a front door for accessing an interior of the cabinet from the front of the cabinet;

a bulkhead positioned within the interior of the cabinet, the bulkhead including a front side that faces toward the front of the cabinet and a rear side that faces toward the rear of the cabinet, the bulkhead defining a termination region and a splitter region, the termination region defining a plurality of spaced openings that are elongated along a top-bottom direction;

a plurality of termination modules mounted at the termination region of the bulkhead, each termination module being disposed in one of the elongated opening, each termination module including a housing holding a plurality of termination adapters, each of the termination adapters having a front port facing the front of the cabinet and a rear port facing the rear of the cabinet, each termination module also including a latching member extending upwardly from a top of the termination module to releasably secure the termination module to the opening; and

a plurality of optical splitter modules mounted at the splitter region of the bulkhead, each of the optical splitter modules being elongated between a front side and a rear side, the front side of each optical splitter module facing the front of the cabinet and the rear side of each optical splitter module facing the rear of the cabinet.

2. The fiber distribution hub of claim 1, further comprising at least one storage module mounted within the cabinet, each storage module being configured to receive and store at least one optical connector terminating an optical fiber extending from one of the optical splitter modules.

3. The fiber distribution hub of claim 2, wherein the storage module is mounted to a storage region defined by the bulkhead.

4. The fiber distribution hub of claim 2, wherein the storage module is mounted to a storage region defined by the front door.

5. The fiber distribution hub of claim 1, wherein labeling is provided on the bulkhead adjacent the elongated openings of the termination region.

6. The fiber distribution hub of claim 1, wherein the elongated openings have rectangular shapes.

7. The fiber distribution hub of claim 1, wherein the plurality of termination adapters includes twelve termination adapters arranged in a column.

8. The fiber distribution hub of claim 1, wherein the bulkhead is part of a swing frame that is pivotally mounted within the interior of the cabinet.

9. The fiber distribution hub of claim 1, further comprising a termination shelf extending rearwardly from the termination region, the termination shelf providing cable management of optical fibers plugged into the rear ports of the termination modules.

10. The fiber distribution hub of claim 1, wherein each termination module is configured to be installed in the respective opening from the rear side of the termination region.

11. The fiber distribution hub of claim 1, wherein the splitter region is disposed at the bulkhead between the termination region and a second termination region.

12. The fiber distribution hub of claim 1, wherein the splitter region is disposed at a top of the bulkhead above the termination region.
