Abstract

A furcation system of an optical fiber assembly includes a fan-out and a transition tube. The fan-out includes a surface and stations. The surface is flexible such that the surface is configured to be changed from flat to curved. The stations are coupled to one side of the surface and are configured to receive and hold sub-units of an optical fiber cable, while allowing the sub-units to project from the stations. The stations are spaced apart from one another such that the stations provide separation between the sub-units received by the stations. Bending of the surface moves the stations from a planar arrangement to a three-dimensional arrangement such that the sub-units may project from the stations of the fan-out in planar and three-dimensional arrays.

Claims

1. A furcation system of an optical fiber cable assembly, comprising:

a fan-out, comprising;

a surface that is flexible such that the surface is configured to be changed from flat to curved; and

stations coupled to one side of the surface, wherein the stations are configured to receive and hold sub-units of an optical fiber cable, while allowing the sub-units to project from the stations;

wherein the stations are spaced apart from one another such that the stations provide separation between the sub-units received by the stations, and wherein bending of the surface moves the stations from a planar arrangement to a three-dimensional arrangement such that the sub-units may project from the stations of the fan-out in planar or three-dimensional arrays; and

a transition tube configured to be attached to the fan-out and the optical fiber cable, wherein the transition tube receives the sub-units from the optical fiber cable and provides the sub-units to the fan-out.

2. The furcation system of claim 1, wherein the surface of the fan-out is configured to be changed from flat to cylindrical such that the three-dimensional arrangement corresponds to a round projection of the sub-units from the fan-out.

3. The furcation system of claim 2, wherein the stations are uniformly positioned between lateral ends of the surface when the surface is flat.

4. The furcation system of claim 3, wherein the fan-out is configured such that the lateral ends of the surface are connected to one another and the surface is in a cylindrical configuration with the stations interior to the cylinder.

5. The furcation system of claim 4, wherein the fan-out further comprises adhesive used to hold the surface of the fan-out in the cylindrical configuration.

6. The furcation system of claim 5, wherein the adhesive additionally holds the transition tube to the fan-out.

7. The furcation system of claim 4, wherein the surface of the fan-out has a raised edge such that, in the cylindrical configuration, the raised edge forms a beveled end to the cylinder.

8. The furcation system of claim 1, wherein the stations include conduits, and wherein the conduits are cylindrical and have open ends such that one of the sub-units may be inserted in one of the open ends and the sub-unit may project from the other of the open ends.

9. The furcation system of claim 8, wherein exterior surfaces of the conduits are configured to contact one another when the fan-out is in a cylindrical configuration such that the conduits provide rigidity to the fan-out to limit further flexing of the fan-out beyond the cylindrical configuration.

10. A fan-out for a furcation system of an optical fiber assembly, comprising:

a surface that is flexible, wherein the surface, in a flat configuration, is elongate and has opposite lateral ends; and

stations for receiving sub-units of an optical fiber cable, wherein the stations are coupled to one side of the surface, between the opposite lateral ends of the surface;

wherein the stations are spaced apart from one another such that the stations provide separation between the sub-units received by the stations; and

wherein the surface is flexible such that the opposite lateral ends of the surface are configured to be connected to one another, forming the fan-out in a cylindrical configuration with the stations on the interior of the cylinder.

11. The fan-out of claim 10, wherein the stations include conduits, and wherein the conduits are cylindrical and have open ends such that one of the sub-units may be inserted in one of the open ends and the sub-unit may pass through the respective conduit and project from the other of the open ends.

12. The fan-out of claim 11, wherein exterior surfaces of the conduits are configured to contact one another when the fan-out is in the cylindrical configuration such that the conduits provide rigidity to the fan-out to limit further flexing of the fan-out beyond the cylindrical configuration.

13. The fan-out of claim 10, wherein the surface has a raised edge such that, in the cylindrical configuration, the raised edge forms a beveled end to the cylinder.

14. The fan-out of claim 13, wherein the stations are positioned along an edge of the surface away from the raised edge.

15. The fan-out of claim 10, further comprising adhesive used to hold the surface in the cylindrical configuration.

16. The fan-out of claim 15, wherein the adhesive is epoxy filling at least a portion of the interior of the cylinder between and around the exterior of the stations.

17. A method of using a furcation system, comprising steps of:

inserting sub-units of an optical fiber cable into first ends of conduits positioned along a surface of a fan-out such that the sub-units extend through the conduits and project from second ends of the conduits, wherein the surface is flexible; and

bending the surface to connect lateral ends of the surface to one another in order to form a cylinder with the conduits interior to the cylinder.

18. The method of claim 17, further comprising a step of fastening together the lateral ends of the surface connected to form the cylinder.

19. The method of claim 18, further comprising steps of:

attaching the cylinder to a transition tube; and

providing epoxy to the interior of the cylinder such that the epoxy fills at least a portion of the interior of the cylinder between and around the exterior of the conduits.

20. The method of claim 17, further comprising a step of removing an end portion of a jacket of the optical fiber cable to expose the sub-units.
