Abstract

A fiber distribution system ( 10 ) includes a fiber distribution hub ( 20, 300 ); at least one fiber distribution terminal ( 30, 100 ); and a cable ( 40 ) wrapped around a spool ( 110 ) of the fiber distribution terminal ( 30, 100 ). The fiber distribution terminal ( 30, 100 ) includes a spool ( 110 ) and a management tray ( 120 ) that rotate together. A second connectorized end ( 40 b ) of the cable ( 40 ) is held at a fiber optic adapter ( 125 ) on the tray ( 120 ). After dispensing the first connectorized end ( 40 a ) to the hub ( 20 ), an optical splitter ( 70, 130, 140 ) can be mounted to the tray ( 120 ). The splitter ( 26, 70, 130, 140, 306 ) has output adapters at which patch cords ( 50 ) can be inserted to connect subscribers to the system. The fiber distribution hub can use the same format of splitters ( 26, 70, 130, 140, 306 ). Other distributed splitter systems are provided with splicing and/or adding of splitters as needed.

First claim

What is claimed is:

1. A fiber distribution terminal comprising:
a base, and an external cover removably mounted to the base;
an internal cover positioned over a cable area which covers a splice and a cable from a riser cable, the internal cover including a surface onto which a splitter device is mounted;
an adapter arranged in the base; and
a connector extending from the splice and mating with the adapter in the base, the connector configured to be removably connected to an output connector through the adapter to provide a single service output, the connector further configured to be removably connected to the splitter device through the adapter to provide multiple service outputs when the output connector is removed from the adapter and the splitter device is mounted onto the surface of the internal cover, wherein the splitter device includes a plurality of splitter outputs with a plurality of splitter adapters, each removably matable with the output connector, and wherein the splitter device includes a splitter input connector for mating with the adapter.

2. The fiber distribution terminal of claim 1 , wherein the external cover is removed from the base when the splitter is connected to the adapter.

3. The fiber distribution terminal of claim 1 , wherein the adapter faces downwardly.

4. The fiber distribution terminal of claim 1 , wherein the splitter includes outputs in the form of adapters which face downwardly.

5. A method of using a fiber distribution terminal comprising:
providing a base including an adapter, an external cover removable from the base, an internal cover positioned over a cable area which covers a splice and a cable from a riser cable, the internal cover including a surface onto which a splitter is mounted;
providing a connector extending from the splice and mating with the adapter in the base, wherein a single output connector is connectable to the connector through the adapter to provide a single service output,
removing the single output connector from the adapter, and
replacing the single output connector with the splitter by mounting the splitter onto the surface of the internal cover, wherein the splitter includes a plurality of splitter outputs with a plurality of splitter adapters, each removably matable with the single output connector, and wherein the splitter includes a splitter input connector for mating with the adapter.

6. The method of claim 5 , further comprising, prior to removing the single output connector, removing the external cover from the base.

7. The method of claim 5 , wherein the adapter faces downwardly.

8. The method of claim 5 , wherein the splitter includes outputs in the form of adapters which face downwardly.

9. A fiber distribution terminal comprising:
a riser cable;
a base defining a channel through which the riser cable is routed, the channel defining a breakout region at which an optical cable of the riser cable is accessed and pulled into the base, the base including a holding location configured to hold a fiber optic base adapter, the base including an internal cover that removably covers the base and includes a surface onto which a splitter device is mounted;
a fiber optic base adapter positioned in the holding location at the base; and
a splice pigtail spliced to the optical cable of the riser cable at a splice at a cable area of the base, the splice pigtail having a connectorized end plugged into one port of the fiber optic base adapter, the connectorized end of the splice pigtail configured to be removably connected to an output connector through the fiber optic base adapter to provide a single service output, the connectorized end of the splice pigtail configured to be removably connected to the splitter device through the fiber optic base adapter to provide multiple service outputs, wherein the splitter device includes a plurality of splitter outputs with a plurality of splitter adapters, each removably matable with the single service output, and wherein the splitter device includes an input including a fiber optic input connector for plugging into the fiber optic base adapter.

10. The fiber distribution terminal of claim 9 , further comprising an external cover removably mounted to the base.

11. The fiber distribution terminal of claim 9 , wherein the internal cover is positioned over the cable area which covers the splice and the optical cable from the riser cable.

12. The fiber distribution terminal of claim 9 , wherein the fiber optic base adapter faces downwardly.

13. The fiber distribution terminal of claim 9 , wherein the breakout region leads to a routing passage that provides slack storage around a spool or bend radius limiter.

14. The fiber distribution terminal of claim 13 , wherein a splicing passage leads from the routing passage to one or more optical splice holders; and wherein a pigtail passage also connects to the routing passage and/or to the splicing passage, the pigtail passage extending to the holding location.

15. The fiber distribution terminal of claim 9 , wherein the input of the splitter connector protrudes from a surface of a rear of the splitter device and the fiber optic output adapters are at a front of the splitter device.

16. The fiber distribution terminal of claim 9 , wherein the outputs of the splitter and the input of the splitter face in opposite directions.

17. The fiber distribution terminal of claim 16 , wherein the outputs of the splitter are facing downwardly and the input of the splitter is facing upwardly.

18. The fiber distribution terminal of claim 9 , wherein the splitter device mounts with a sliding motion.

19. A fiber distribution terminal for use with a riser cable including an optical cable comprising:
a base and an external cover removably mounted to the base, the base defining a channel through which the riser cable is routed, the channel defining a breakout region at which the optical cable of the riser cable is accessed and pulled into the base, the breakout region leading to a routing passage that provides slack storage around a spool or bend radius limiter, the base including a holding location configured to hold a fiber optic base adapter, the base at least partially configured to mount a splitter device;
a fiber optic base adapter positioned in the holding location at the base;
wherein a splice pigtail is spliced at a splice to the optical cable of the riser cable at a cable area of the base, the splice pigtail having a connectorized end pluggable into one port of the fiber optic base adapter;
an internal cover positioned over the cable area which covers the splice and the optical cable of the riser cable, the internal cover including a splitter mount surface; and
a splitter device removably mounted onto the splitter mount surface, wherein the splitter device mounts with a sliding motion onto the splitter mount surface, the splitter device having a front and a rear, the splitter device including an input at the rear, a plurality of outputs at the front, and a splitter component between the input and the outputs, the input being in the form of a fiber optic input connector, the outputs being in the form of fiber optic output adapters, the fiber optic input connector protruding from a surface of the rear, the fiber optic input connector and the fiber optic output adapters facing in opposite directions, the fiber optic input connector plugged into the fiber optic base adapter.

20. The fiber distribution terminal of claim 19 , wherein the fiber optic base adapter faces downwardly.
