Abstract

A fiber distribution device includes a swing frame chassis pivotally mounted to a support structure. At least a first optical splitter module is mounted to the swing frame chassis. Pigtails having connectorized ends are carried by the swing frame chassis and have portions that are routed generally vertically on the swing frame chassis. An optical termination field includes fiber optic adapters carried by the swing frame chassis. The fiber optic adapters are configured to receive the connectorized ends of the pigtails.

Claims

1. A fiber distribution device comprising:

a swing frame chassis pivotally mounted to a support structure;

at least a first optical splitter module mounted to the swing frame chassis, the first optical splitter module being configured to receive an incoming optical signal and to split the incoming optical signal into a plurality of output signals;

a plurality of pigtails having connectorized ends, the pigtails being carried by the swing frame chassis, each of the pigtails being configured to transmit one of the output signals split by the first optical splitter module, the pigtails having portions that are routed generally vertically on the swing frame chassis; and

an optical termination field including a plurality of fiber optic adapters carried by the swing frame chassis, the fiber optic adapters being configured to receive the connectorized ends of the pigtails.

2. The fiber distribution device of claim 1, further comprising an outside-rated enclosure configured to enclose the swing frame chassis.

3. The fiber distribution device of claim 2, wherein the support structure includes a wall of the enclosure.

4. The fiber distribution device of claim 1, further comprising fiber management brackets carried by the swing frame chassis for generally vertically routing the portions of the pigtails on the swing frame chassis.

5. The fiber distribution device of claim 1, wherein the fiber optic adapters of the optical termination field are arranged into a plurality of rows.

6. The fiber distribution device of claim 5, wherein the rows of adapters are vertically offset from each other.

7. The fiber distribution device of claim 1, further comprising a fiber management channel carried by the swing frame chassis for routing the pigtails on the swing frame chassis.

8. The fiber distribution device of claim 1, further comprising fiber bend radius limiters carried by the swing frame chassis for managing the pigtails on the swing frame chassis.

9. The fiber distribution device of claim 1, further comprising a shelf carried by the swing frame chassis.

10. The fiber distribution device of claim 1, further comprising a splice location carried by the swing frame chassis.

11. The fiber distribution device of claim 10, wherein the splice location includes a splice tray.

12. The fiber distribution device of claim 1, further comprising a fiber optic connector storage location at which the connectorized ends of the pigtails can be stored when not received within the fiber optic adapters of the optical termination field, the connector storage location being carried by the swing frame chassis.

13. The fiber distribution device of claim 12, wherein the fiber optic connector storage location includes a plurality of receptacles each configured for receiving one of the connectorized ends of the pigtails, and wherein the receptacles are not functional fiber optic adapters.

14. The fiber distribution device of claim of claim 1, wherein the optical splitter module mounts to the swing frame chassis at a splitter module mounting location that is vertically offset from the optical termination field.

15. The fiber distribution device of claim 1, further comprising a vertically extending fiber management channel carried by the swing frame chassis that is configured to route at least portions of the pigtails on the swing frame chassis from the first optical splitter module to the optical termination field.

16. The fiber distribution device of claim 1, wherein the optical termination field carried by the swing frame chassis includes at least 144 of the fiber optic adapters.

17. A fiber distribution device comprising:

a swing frame chassis pivotally mounted to a support structure, the swing frame being configured to pivot relative to the support structure between an open position and a closed position;

at least a first optical splitter module mounted to the swing frame chassis, the first optical splitter module being configured to receive an incoming optical signal and to split the incoming optical signal into a plurality of output signals;

a plurality of pigtails having connectorized ends, the pigtails being carried by the swing frame chassis, the pigtails being accessible when the swing frame chassis is arranged in the closed position, each of the pigtails being configured to transmit one of the output signals split by the first optical splitter module; and

an optical termination field including a plurality of fiber optic adapters carried by the swing frame chassis, the fiber optic adapters being configured to receive the connectorized ends of the pigtails.

18. The fiber distribution device of claim of claim 17, wherein the optical splitter module is vertically offset from the optical termination field.

19. The fiber distribution device of claim 17, further comprising an outside-rated enclosure configured to enclose the swing frame chassis.

20. The fiber distribution device of claim 17, wherein the support structure includes a wall of the enclosure.

21. The fiber distribution device of claim 17, further comprising a vertically extending fiber management channel carried by the swing frame chassis that is configured to route at least portions of the pigtails on the swing frame chassis from the first optical splitter module to the optical termination field.

22. The fiber distribution device of claim 21, further comprising fiber management brackets carried by the swing frame chassis for generally vertically routing at least portions of the pigtails on the swing frame chassis.

23. The fiber distribution device of claim 17, further comprising fiber management brackets carried by the swing frame chassis for routing the pigtails on the swing frame chassis.
