Low profile fiber distribution hub
Certain embodiments of a fiber distribution hub include a swing frame pivotally mounted within an enclosure having a low profile. For example, the enclosure can have a depth of less than about nine inches. Termination modules can be mounted to the swing frame and oriented to slide at least partially in a front-to-rear direction to facilitate access to connectors plugged into the termination modules. Splitter modules and connector storage regions can be provided within the enclosure.
1. A fiber distribution hub comprising:
an enclosure defining an interior region, the enclosure including a depth that extends from a front to a back of the enclosure, the front of the enclosure including an access opening for accessing the interior of the enclosure, the enclosure also including a front door for at least partially covering the access opening, the front door having a first vertical pivot axis, the depth of the enclosure being less than 9 inches, wherein a width of the enclosure is at least 1.5 times the depth and a height of the enclosure is at least 3 times the depth;
a splitter module mounting location positioned within the enclosure, the splitter module mounting location being adapted to mount one or more splitter modules within the enclosure;
a pivotal structure pivotally mounted within the enclosure, the pivotal structure having a second vertical pivot axis positioned adjacent to the first vertical pivot axis; and
a termination field including at least one hundred forty-four fiber optic adapters, the termination field being carried by the pivotal structure, the termination field including a plurality of adapter modules each including a plurality of fiber optic adapters, each adapter module being movable relative to the pivotal structure between an extended position and a retracted position.
2. The fiber distribution hub of claim 1 , wherein at least one splitter module is mounted at the splitter module mounting location, the splitter module including a housing enclosing an optical splitter.
3. The fiber distribution hub of claim 2 , wherein the splitter module includes a plurality of connectorized pigtails that extend away from the housing for carrying a signal split at the optical splitter, the connectorized pigtails having connectorized ends.
4. The fiber distribution hub of claim 3 , wherein the connectorized pigtails are long enough to extend from the splitter module mounting location to the termination field so that the connectorized ends can be inserted into the fiber optic adapters of the termination field.
5. The fiber distribution hub of claim 3 , wherein the connectorized pigtails are long enough to extend from the splitter module mounting location to a connector storage location so that the connectorized ends can be stored at the connector storage location.
6. The fiber distribution hub of claim 1 , wherein the fiber distribution hub includes at least 288 circuits.
7. The fiber distribution hub of claim 1 , wherein the fiber distribution hub includes at least 576 circuits.
8. The fiber distribution hub of claim 1 , wherein the pivotal structure includes a swing frame having a width that generally corresponds to the width of the enclosure and a height that generally corresponds to the height of the enclosure.
9. The fiber distribution hub of claim 8 , wherein the swing frame has a depth that is shorter than the depth of the enclosure to accommodate cables and cable management structures provided within the interior of the enclosure at a location behind the swing frame.
10. The fiber distribution hub of claim 8 , wherein the splitter module mounting location is located at a top of the swing frame.
11. The fiber distribution hub of claim 8 , wherein the swing frame defines a vertical cable routing path at an end of the swing frame positioned distal from the second vertical pivot axis.
12. The fiber distribution hub of claim 1 , wherein the depth of the enclosure is less than 8 inches.
13. The fiber distribution hub of claim 1 , wherein the height of the enclosure is at least four times the depth of the enclosure, and wherein the width of the enclosure is at least two times the depth of the enclosure.
14. The fiber distribution hub of claim 1 , wherein the height of the enclosure is at least 5 times the depth of the enclosure, and wherein the width of the enclosure is at least 2 times the depth of the enclosure.
