Abstract

A cable assembly including a fiber optic cable and at least one network access point positioned on the cable at which at least one optical fiber within the cable is accessed and preterminated. The cable assembly comprises a tether adapted to be selectively extended and including at least one tether optical fiber therein that is optically connected to the at least one optical fiber that is preterminated, and a tether storage member for storing at least a portion of the tether therein, wherein at least one of the at least one optical fiber that is preterminated and the at least one tether optical fiber comprises a bend performance optical fiber.

Claims

1. A cable assembly including a fiber optic cable and at least one network access point positioned on the cable at which at least one optical fiber within the cable is accessed and preterminated, the cable assembly comprising:

a tether adapted to be selectively extended relative to the network access point and including at least one tether optical fiber therein that is optically connected to the at least one preterminated optical fiber; and

a tether storage member for storing at least a portion of the tether therein, wherein the tether portion is moveable therein;

wherein at least one of the at least one preterminated optical fiber and the at least one tether optical fiber comprises a bend performance optical fiber.

2. The cable assembly of claim 1, wherein the tether is adapted to be selectively retracted.

3. The cable assembly of claim 1, wherein the bend performance optical fiber performs at least one 180 degree turn or loop within the tether storage member.

4. The cable assembly of claim 1, further comprising a body substantially enclosing the at least one network access point.

5. The cable assembly of claim 4, wherein the body is an overmolded body.

6. The cable assembly of claim 4, wherein the body is flexible.

7. The cable assembly of claim 4, wherein the body secures at least a portion of the tether storage member.

8. The cable assembly of claim 1, wherein the tether is preconnectorized.

9. The cable assembly of claim 1, further comprising a lanyard for limiting the extension of the tether.

10. The cable assembly of claim 1, wherein the tether storage member is internal to the fiber optic cable.

11. The cable assembly of claim 1, wherein the tether storage member is external to the fiber optic cable.

12. The cable assembly of claim 1, wherein the bend performance optical fiber is a microstructured optical fiber comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes and the microstructured fiber having a 12 mm macrobend induced loss at 1550 nm of less than 0.1 dB/turn.

13. The cable assembly of claim 1, wherein the bend performance optical fiber is a microstructured optical fiber comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes and the microstructured fiber having a 12 mm macrobend induced loss at 1550 nm of less than 0.05 dB/turn.

14. The cable assembly of claim 1, wherein the bend performance optical fiber is a microstructured optical fiber comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes and the microstructured fiber having an 8 mm macrobend induced loss at 1550 nm of less than 0.2 dB/turn.

15. The cable assembly of claim 1, wherein the bend performance optical fiber is a microstructured optical fiber comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes and the microstructured fiber having an 8 mm macrobend induced loss at 1550 nm of less than 0.1 dB/turn.

16. A cable assembly including a fiber optic cable and at least one network access point positioned on the cable at which at least one optical fiber within the cable is accessed and preterminated, the cable assembly comprising:

a connectorized tether including a first tether portion that is stationary, a second tether portion that is adapted to be selectively extended relative to the network access point and to the first tether portion, and at least one tether optical fiber therein that is spliced to the at least one preterminated optical fiber;

wherein at least one of the at least one preterminated optical fiber and the at least one tether optical fiber being a bend performance optical fiber.

17. The cable assembly of claim 16, wherein the second tether portion is adapted to be selectively retracted.

18. The cable assembly of claim 16, wherein the bend performance optical fiber performs at least one 180 degree turn or loop within the first tether portion.

19. The cable assembly of claim 16, further comprising a flexible body substantially encapsulating the at least one network access point.

20. The cable assembly of claim 16, further comprising a lanyard for limiting the extension of the tether.

21. The cable assembly of claim 16, wherein the first tether portion is internal to the fiber optic cable.

22. The cable assembly of claim 16, wherein the first tether portion is external to the fiber optic cable.
