Abstract

A breakout assembly for transitioning a multi-fibre optical cable into one or more individual fibres is disclosed. The breakout assembly includes a first housing segment engageable at a first end to the cable and engageable at a second end with one or more furcation tubes that each receive an individual fibre from the cable, and a second housing segment engageable at a first end to the cable and engageable at a second end with one or more furcation tubes that each receive an individual fibre from the cable. The first housing segment is securable to the second housing segment so as to encapsulate at least a portion of the individual fibres as they break out from the cable.

Claims (44)

1. An assembly for transitioning a multi-fiber optical cable into one or more individual fibers, the assembly comprising:

a first housing segment engageable at a first end to the cable, the cable defining a longitudinal axis, the longitudinal axis defining a radial dimension extending away from the longitudinal axis;

a second housing segment engageable at a first end to the cable, the first housing segment being securable to the second housing segment so as to encapsulate at least a portion of the individual fibers as they extend from the cable; and

first and second swage members,

wherein each of the first and second housing segment is configured to receive a strength member of the cable such that a swaging portion of each strength member is positioned between a pair of spaced apart opposing wall portions of the corresponding housing segment; and

wherein the first and second swage members are configured to be crimped on to the swaging portions of the strength members by pressing the first and second swage members onto the swaging portions of the strength members in directions that are radially toward the longitudinal axis.

2. The assembly of claim 1 , wherein each of the swaging portions extends from one of the corresponding opposing wall portions to the other of the corresponding opposing wall portions of the corresponding housing segment.

3. The assembly of claim 2 , wherein each of the swage members is configured to extend from one of the corresponding opposing wall portions to the other of the corresponding opposing wall portions of the corresponding housing segment.

4. The assembly of claim 1 , further comprising a heatshrink component adapted to cover the first and second housing segments.

5. The assembly of claim 1 , wherein each of the first and second housing segment is engageable at a second end with one or more furcation tubes that each receive one of the individual fibers extending from the cable.

6. The assembly of claim 5 , wherein one or more furcation tubing connectors extend from the second end of each housing segment.

7. The assembly of claim 6 , wherein the one or more furcation tubes are secured to the one or more furcation tubing connectors.

8. The assembly of claim 7 , wherein each of the furcation tubes is crimped onto a corresponding furcation tubing connector using a crimp sleeve.

9. The assembly of claim 8 , wherein a heat shrink is applied over a portion of each furcation tube and corresponding crimp sleeve.

10. The assembly of claim 1 , wherein the first and second housing segments are identical.

11. The assembly of claim 1 , wherein each of the housing segments defines a channel for receiving a portion of the individual fibers extending from the cable.

12. The assembly of claim 11 , wherein the channels cooperate to define an enclosed passage adapted to encapsulate the portions of the individual fibers extending from the cable.

13. The assembly of claim 12 , wherein at least one of the channels is at least partially filled with a resin adhesive or a gel material.

14. The assembly of claim 13 , wherein the channel of each housing segment leads into one or more passageways, each passageway adapted to receive an inner tube of a furcation tube through which one of the individual fibers can be fed.

15. The assembly of claim 1 , wherein the first and second housing segments are latchable together.

16. The assembly of claim 1 , wherein the cable is a ribbon cable.

17. The assembly of claim 1 , wherein the strength members are rods or tubes.

18. An assembly, comprising:

an optical cable including a plurality of optical fibers and a pair of strength members, the optical cable defining a longitudinal axis, the longitudinal axis defining a radial dimension extending away from the longitudinal axis;

a first housing segment engaged at a first end to the cable;

a second housing segment engaged at a first end to the cable, the first and second housing segments encapsulating portions of the fibers as they extend from the cable; and

first and second swage members,

wherein each of the first and second housing segment receives one of the strength members such that a swaging portion of each strength member is positioned between a pair of spaced apart opposing wall portions of the corresponding housing segment; and

wherein the first and second swage members are crimped on to the swaging portions of the strength members by pressing the first and second swage members onto the swaging portions of the strength members in directions that are radially toward the longitudinal axis.

19. The assembly of claim 18 , further comprising one or more single fiber optical connectors terminated onto one or more of the plurality of fibers.

20. A method of assembling an assembly onto a multi-fiber optical cable, the assembly including a first housing segment and a second housing segment, the optical cable defining a longitudinal axis, the longitudinal axis defining a radial dimension extending away from the longitudinal axis, the method including:

locating the cable into a first end of the first housing segment;

securing the first housing segment to the second housing segment so as to encapsulate at least portions of individual fibers extending from the cable;

positioning a pair of strength members of the cable into the first and second housing segments to expose a swaging portion of each strength member; and

crimping a swage member onto the swaging portion of each strength member by pressing the swage members onto the swaging portions of the strength members in directions that are radially toward the longitudinal axis.

21. The method of claim 20 , wherein each of the housing segments includes a channel for receiving the portions of individual fibers extending from the cable, and the method further comprises at least partially filling at least one of the channels with a resin adhesive or a gel material.

22. The method of claim 21 , further including covering the first and second housing segments by applying a heatshrink or overmould thereto.

23. An assembly for transitioning a multi-fiber optical cable into one or more individual fibers, the assembly comprising:

a first housing segment engageable at a first end to the cable;

a second housing segment engageable at a first end to the cable, the first housing segment being securable to the second housing segment so as to encapsulate at least a portion of the individual fibers as they extend from the cable; and

first and second swage members,

wherein each of the first and second housing segment is configured to receive a strength member of the cable such that a swaging portion of each strength member is positioned outside the corresponding housing segment and between a pair of spaced apart opposing wall portions of the corresponding housing segment;

wherein the first and second swage members are configured to be crimped on to the swaging portions of the strength members; and

wherein each of the swaging portions extends from one of the corresponding opposing wall portions to the other of the corresponding opposing wall portions of the corresponding housing segment.
