Abstract

A fiber optic transition assembly includes a drop cable including a plurality of optical fibers and an outer jacket. The assembly further includes a plurality of furcation cables, each of the plurality of furcation cables surrounding an extended portion of one of the plurality of optical fibers. The assembly further includes a plurality of biasing members, each of the plurality of biasing members surrounding a first end portion of each of the plurality of furcation cables. The assembly further includes a transition member defining an interior, wherein a second end of the outer jacket and first ends of each of the plurality of furcation cables are disposed within the interior, each of the plurality of biasing members is at least partially disposed within the interior, and the plurality of optical fibers extend from the outer jacket to the furcation cables within the interior.

First claim

a plurality of furcation cables, each of the plurality of furcation cables surrounding an extended portion of one of the plurality of optical fibers, each of the plurality of furcation cables extending between a first end and a second end;
a plurality of biasing members, each of the plurality of biasing members surrounding a first end portion of one of the plurality of furcation cables, and the first end portion of each of the plurality of furcation cables surrounded by one of the plurality of biasing members; and
a transition member defining an interior, wherein the second end of the outer jacket and the first ends of each of the plurality of furcation cables are disposed within the interior, each of the plurality of biasing members is at least partially disposed within the interior, and the plurality of optical fibers extend from the outer jacket to the furcation cables within the interior.

2. The fiber optic transition assembly of claim 1 , wherein each of the plurality of biasing members is a coil spring.

3. The fiber optic transition assembly of claim 1 , wherein the drop cable further comprises a plurality of strength rods.

4. The fiber optic transition assembly of claim 3 , wherein each of the plurality of strength rods extends from the second end of the outer jacket into the interior.

5. The fiber optic transition assembly of claim 1 , further comprising a plurality of heat shrink tubes, each of the plurality of heat shrink tubes surrounding the first end portion of one of the plurality of furcation cables and the one of the plurality of biasing members surrounding the first end portion of that furcation cable.

6. The fiber optic transition assembly of claim 1 , wherein each of the plurality of biasing members extends from the transition member.

7. The fiber optic transition assembly of claim 1 , wherein the transition member extends between a first end and a second end, wherein the drop cable enters the first end of the transition member, and wherein each of the plurality of furcation cables enters the second end of the transition member.

8. The fiber optic transition assembly of claim 7 , further comprising a heat shrink tube, the heat shrink tube surrounding the first end of the transition member and a portion of the drop cable extending from the first end of the transition member.

9. The fiber optic transition assembly of claim 1 , further comprising an adhesive disposed within the interior.

10. The fiber optic transition assembly of claim 1 , further comprising:
a plurality of connectors, each of the plurality of connectors comprising a body extending between a first end and a second end,
wherein the second end of each of the plurality of furcation cables is disposed within one of the plurality of connectors and each of the plurality of optical fibers extends from the second end of one of the plurality of furcation cables within each of the plurality of connectors.

11. The fiber optic transition assembly of claim 10 , wherein the plurality of biasing members are a plurality of first biasing members, and further comprising a plurality of second biasing members, each of the plurality of second biasing members surrounding a second end portion of one of the plurality of furcation cables, and the second end portion of each of the plurality of furcation cables surrounded by one of the plurality of second biasing members.

12. The fiber optic transition assembly of claim 11 , wherein each of the plurality of second biasing members is at least partially disposed within one of the plurality of connectors.

13. The fiber optic transition assembly of claim 11 , wherein each of the plurality of second biasing members is a coil spring.

14. The fiber optic transition assembly of claim 11 , further comprising a plurality of heat shrink tubes, each of the plurality of heat shrink tubes surrounding the second end portion of one of the plurality of furcation cables and the one of the plurality of second biasing members surrounding the second end portion of that furcation cable.

15. The fiber optic transition assembly of claim 14 , further comprising a plurality of boots, wherein the first end of the body of each of the plurality of connectors is disposed within one of the plurality of boots, and wherein one of the plurality of heat shrink tubes, one of the plurality of second biasing members, and the second end portion of one of the plurality of furcation cables are at least partially disposed within each of the plurality of boots.

16. A fiber optic transition assembly, comprising:
