Abstract

A tapered fiber optic distribution cable that includes a plurality of drop cables (2) having at least one predetermined breakout location where a drop cable is withdrawn from the tapered distribution cable. The drop cables are bound together to form the tapered fiber optic distribution cable by binding members (5) or helical winding. Each drop cable (2) contains a plurality of optical fibers which may be reconnectorized according to a user'"'"'s preferences.

Claims

1. A tapered fiber optic distribution cable, comprising:

a plurality of drop cables bundled together; and

a breakout point located along the tapered fiber optic distribution cable,

wherein one of the drop cables has a first length shorter than a second length of the tapered fiber optic distribution cable and has an end terminating at the breakout point.

2. The tapered fiber optic distribution cable according to claim 1, wherein a substantial portion of an exterior of the tapered fiber optic distribution cable comprises a portion of the plurality of drop cables.

3. The tapered fiber optic distribution cable according to claim 1, wherein the plurality of drop cables are bundled by helical winding.

4. The tapered fiber optic distribution cable according to claim 1, wherein the plurality of drop cables are bundled together by a binding member.

5. The tapered fiber optic distribution cable according to claim 1, wherein at least one of the drop cables is pre-fitted with an optical fitting.

6. The tapered fiber optic distribution cable according to claim 1, further comprising a plurality of binding members disposed at intermittent locations along the length of the tapered fiber optic distribution cable, wherein each of the binding members comprise a collar.

7. The tapered fiber optic distribution cable according the claim 1, wherein the binding member comprises a wire wrapped around the drop cables.

8. The tapered fiber optic distribution cable according the claim 1, further comprising a core cable, wherein the drop cables are helically wound around the core cable.

9. The tapered fiber optic distribution cable according to claim 5, wherein the core cable comprises a drop cable having a length equal to the total length.

10. The tapered fiber optic distribution cable according to claim 1, wherein at least one of the drop cables comprises a plurality of optical fibers, at least one of said optical fibers is fitted with an individual fiber optic connector.

11. The tapered fiber optic distribution cable according to claim 1, wherein at least one of the drop cables comprises a plurality of optical fibers, at least two of said optical fibers are fitted with a single connector.

14. The tapered fiber optic distribution cable according to claim 9, wherein said binding member comprises at least one of a wire, a sheath, an adhesive and a collar.

12. A tapered fiber optic distribution cable, comprising:

a first drop cable having a first predetermined length and containing a first number of optical fibers;

a second drop cable having a second predetermined length and containing a second number of optical fibers; and

a binding member to secure the first drop cable and the second drop cable together,

wherein each of the first number of optical fibers and each of the second number of optical fibers are different and the first predetermined length and the second predetermined length are different.

13. The tapered fiber optic distribution cable according to claim 12, wherein a substantial portion of the exterior of the tapered fiber optic distribution cable comprises at least one of the first drop cable and the second drop cable.

15. A method of making a tapered fiber optic distribution cable, the method comprising;

providing a plurality of drop cables;

cutting one of drop cables to a predetermined breakout length to make a cut drop cable; and

binding the drop cables together.

16. The method of making a tapered fiber optic distribution cable according to claim 15, wherein the drop cables are bound together by helically winding the drop cables.

17. The method of making a tapered fiber optic distribution cable according to claim 15, wherein the drop cables are bound together by at least one of a binder clip, tape, shrink wrap and adhesive.

18. The method of making a tapered fiber optic distribution cable according to claim 15, further comprising:

binding the cut drop cable to the other drop cables at a breakout location corresponding to the predetermined breakout length with at least one of a binder clip, tape, shrink wrap and adhesive.

19. The method of making a tapered fiber optic distribution cable according to claim 18, further comprising:

preparing an end of the cut drop cable near the breakout location with an optical connector.
