Abstract

The present disclosure relates to a telecommunications distribution hub having a cabinet that defines a primary compartment. The cabinet also includes one or more main doors for accessing the primary compartment. Telecommunications equipment is mounted within the primary compartment. The distribution hub further includes a secondary compartment that can be accessed from an exterior of the cabinet without accessing the primary compartment. A grounding interface is accessible from within the secondary compartment.

Claims

1. An enclosure for connecting incoming and outgoing fibers, the enclosure comprising:

a housing defining an interior, an input cable port leading to the interior, and an output cable port leading to the interior;

a termination region disposed within the interior of the housing, the termination region having a first side and a second side, the termination region defining a dividing line between the incoming fibers at the first side of the termination region and the outgoing fibers at the second side of the termination region;

a splitter region disposed within the interior of the housing;

a first routing path leading from the input cable port to the splitter region and from the splitter region to the first side of the termination region;

a second routing path leading from the input cable port to the first side of the termination region and bypassing the splitter region en route to the first side of the termination region; and

a third routing path leading from the second side of the termination region to the output cable port.

2. The enclosure of claim 1, further comprising a second termination region disposed along at least one of the first and second routing paths between the input cable port and the termination region.

3. The enclosure of claim 2, further comprising an optical adapter disposed at the second termination region.

4. The enclosure of claim 3, wherein the optical adapter is one of a plurality of optical adapters disposed at the second termination region.

5. The enclosure of claim 4, wherein the optical adapters include sliding adapter packs.

6. The enclosure of claim 2, wherein the termination region carries both optical adapters and connector holders.

7. The enclosure of claim 3, wherein the termination region, second termination region, and splitter region are carried by a frame that pivots relative to the housing.

8. The enclosure of claim 1, further comprising:

an optical splitter disposed at the splitter region;

a splitter input fiber routed partially along the first routing path to the optical splitter;

a plurality of splitter pigtails output from the optical splitter, the splitter pigtails being routed partially along the first routing path from the optical splitter towards the termination region; and

a pass-through fiber routed partially along the second routing path to the termination region.

9. The enclosure of claim 8, further comprising a second termination region disposed along at least one of the first and second routing paths between the input cable port and the termination region.

10. The enclosure of claim 9, wherein the splitter input fiber ex en from the second termination region to the optical splitter.

11. The enclosure of claim 10, wherein the pass-through fiber extends from the second termination region to the termination region.

12. The enclosure of claim 9, wherein the pass-through fiber extends from the second termination region to the termination region.

13. The enclosure of claim 9, further comprising a splice tray disposed along the first routing path, wherein the splitter input fiber extends between the splice tray and the optical splitter.

14. The enclosure of claim 13, wherein the pass-through fiber extends between the second termination region and the termination region.

15. The enclosure of claim 8, wherein the termination region carries both optical adapters and connector holders.

16. An enclosure for connecting incoming and outgoing fibers, the enclosure comprising:

a housing defining an interior;

a first termination region disposed within the interior of the housing, the first termination region including a plurality of optical adapters, each optical adapter having a first port and a second port, the second ports of the optical adapters being optically coupled to the outgoing fibers;

an optical splitter disposed within the interior;

a second termination region disposed within the interior separate from the first termination region;

first and second incoming fibers routed into the interior of the housing and to the second termination region;

a splitter input fiber extending between first and second ends, the first end being optically coupled to the first incoming fiber at the second termination region, the second end being optically coupled to an input of the optical splitter; and

a plurality of splitter pigtails output from the optical splitter, the splitter pigtails having connectorized ends routed towards the first ports of the optical adapters at the first termination region;

a pass-through fiber having a first end optically coupled to the second incoming fiber at the second termination region, the pass-through fiber having a connectorized end routed towards the first ports of the optical adapters of the first termination region.

17. The enclosure of claim 16, further comprising a connector holder mounted at the termination region, the connector holder receiving the connectorized ends of the splitter pigtails and the pass-through fiber.

18. The enclosure of claim 16, wherein the connectorized end of the pass-through fiber is received at an optical adapter disposed at the first termination region.

19. The enclosure of claim 16, wherein a plurality of optical adapters are disposed at the second termination region.

20. The enclosure of claim 16, wherein a splice tray is disposed at the second termination region.
