Abstract

A cable slack handling device including a base portion with a first lobe and a second lobe each joined with the base portion. The first and second lobes each have an arcuate exterior wall portion to accommodate cable slack around a perimeter of the cable slack handling device. A connection device holder is located between a portion of the first and second lobes. The connection device holder is adapted to contain cable connection devices. The connection device holder has two opposite ends each adapted to receive cables.

Claims

1. A cable slack handling device comprising:

a base portion;

a first lobe and a second lobe each joined with the base portion;

at least one arcuate exterior wall portion on each of the first and second lobes, the arcuate exterior wall portions adapted to accommodate cable slack around a perimeter of the device;

at least two interior wall portions on each of the first and second lobes defining a first channel and a second channel disposed between the first and second lobes, the first and second channels adapted to receive one or more cables; and

a connection device holder disposed between at least a portion of the first and second lobes and disposed between at least a portion of the first and second channels, the connection device holder adapted to contain one or more connection devices that receive the cables from the channels.

2. The device as defined by claim 1, wherein the width of each channel between the first lobe and the second lobe is less than or substantially equal to the width of the connection device holder.

3. The device as defined by claim 1, wherein the arcuate exterior wall portion of the first lobe and the arcuate exterior wall portion of the second lobe cooperate to form a substantially circular exterior wall configuration to accommodate cable slack in a substantially circular arrangement.

4. The device as defined by claim 1, wherein a part of each of the interior wall portions of the first and second lobes is arcuate and has a radius of curvature less than the radius of curvature of the arcuate exterior wall portions of the first and second lobes.

6. The device as defined by claim 1, wherein a part of each of the interior wall portions of the first and second lobes has a radius of curvature substantially equal to the radius of curvature of a part of the arcuate exterior wall portions of the first and second lobes, wherein the first and second lobes further comprise a linear exterior wall portion having a substantially planar surface and adapted to accommodate cable slack around the perimeter of the cable slack handling device, wherein the linear exterior wall portions of the first and second lobes are substantially parallel.

7. The device as defined by claim 1, wherein the connection device is selected from the group consisting of:

mechanical splices, fusion splices, splitters, couplers, connectors, and passive optical devices.

8. The device as defined by claim 1, wherein a portion of at least one of the interior walls of each lobe is arcuate and has a radius of curvature of less than about 30 mm.

9. The device as defined by claim 1, wherein the connection device holder is positioned at an angle relative to the base portion such that the connection device holder is adapted to direct an input end of the cables in an input path around the exterior wall portions of the lobes and adapted to direct an output end of the cables in an output path around the exterior wall portions of the lobes to thereby separate the input path of the input end of the cables from the output path of the output end of the cables.

10. The device as defined by claim 9, further comprising a plurality of protuberances extending radially outward from the exterior wall portion of the lobes comprising at least one center protuberance, at least one first protuberance on one side of the center protuberance, and at least one second protuberance on the other side of the center protuberance, wherein the space between the first protuberances and the center protuberances defines the input path, and wherein the space between the second protuberances and the center protuberances defines the output path.

5. (canceled)

11. A cable slack handling device comprising:

a base portion;

a plurality of cables each containing one or more optical fibers;

a plurality of connection devices for connecting the fibers; and

a first lobe and a second lobe each joined with the base portion;

at least one arcuate exterior wall portion on each of the first and second lobes, the arcuate exterior wall portions to accommodate cable slack around a perimeter of the device;

at least two interior wall portions on each of the first and second lobes defining a first channel and a second channel disposed between the first and second lobes, the first and second channels adapted to receive one or more cables; and

a connection device holder disposed between at least a portion of the first and second lobes and disposed between at least a portion of the first and second channels, the connection device holder adapted to contain one or more connection devices that receive the cables from the channels.

12. The device as defined by claim 11, wherein the one or more connection devices is selected from the group consisting of:

mechanical splices, fusion splices, splitters, couplers, connectors, and passive optical devices.

13. The device as defined by claim 11, wherein the cables comprise multi-fiber cables.

14. The device as defined by claim 11, wherein the connection device holder is positioned at an angle relative to the base portion such that the connection device holder directs an input end of the cables in an input path around the exterior wall portions of the lobes and directs an output end of the cables in an output path around the exterior wall portions of the lobes to thereby separate the input path of the input end of the cables from the output path of the output end of the cables.

15. The device as defined by claim 14, further comprising a plurality of protuberances extending radially outward from the exterior wall portion of the lobes comprising at least one center protuberance, at least one first protuberance on one side of the center protuberance, and at least one second protuberance on the other side of the center protuberance, wherein the space between the first protuberances and the center protuberances defines the input path, and wherein the space between the second protuberances and the center protuberances defines the output path.

16. A system for handling cable slack comprising:

a housing; and

a cable slack handling device mounted to the housing, the cable slack handling device comprising;

a base portion;

one or more cables containing one or more optical fibers;

a plurality of connection devices for connecting the fibers;

a first lobe and a second lobe each joined with the base portion;

at least one arcuate exterior wall portion on each of the first and second lobes, the arcuate exterior wall portions to accommodate cable slack around a perimeter of the device;

at least two interior wall portions on each of the first and second lobes defining a first channel and a second channel disposed between the first and second lobes, the first and second channels adapted to receive one or more cables; and

a connection device holder disposed between at least a portion of the first and second lobes and disposed between at least a portion of the first and second channels, the connection device holder adapted to contain one or more connection devices that receive the cables from the channels.

17. The device as defined by claim 16, wherein the cable slack handling device is rotatably mounted to the housing.

18. The device as defined by claim 16, wherein the housing comprises a drawer adapted to facilitate connection to telecommunications equipment.

19. The device as defined by claim 16, wherein the housing comprises a connection device tray adapted to facilitate connection between one set of telecommunication lines and another set of telecommunication lines.
