Abstract

A fiber optic cable assembly includes a fiber optic cable and a connector assembly. The fiber optic cable includes an optical fiber, having a core surrounded by a cladding, and a jacket, which surrounds the optical fiber. The jacket includes a plurality of reinforcement members integrated into a matrix material of the jacket. The connector assembly includes a rear housing having a connector end that is directly engaged with an end portion of the jacket. A fiber optic cable includes an optical fiber with a core surrounded by a cladding. The fiber optic cable also includes a jacket that surrounds the optical fiber. The jacket includes about 40% to about 70% by weight of a plurality of reinforcement members integrated into a matrix material of the jacket.

Claims

1. A fiber optic cable assembly comprising:

a fiber optic cable including;

an optical fiber having a core surrounded by a cladding;

a jacket surrounding the optical fiber, the jacket including a plurality of reinforcement members integrated into a matrix material of the jacket;

wherein the fiber optic cable does not include a separate strength layer; and

a connector assembly including a rear housing having a connector end to which an end portion of the jacket is directly anchored, wherein a pull-out force required to disengage the connector assembly from the fiber optic cable is at least about twenty-six pounds.

2. A fiber optic cable assembly as claimed in claim 1, wherein an outer perimeter of the end portion of the jacket has a texturized surface and wherein the connector assembly engages the texturized surface of the jacket.

3. A fiber optic cable assembly as claimed in claim 2, wherein the texturized surface includes a plurality of external threads.

4. A fiber optic cable assembly as claimed in claim 3, wherein the connector assembly is in threaded engagement with the texturized surface of the jacket.

5. A fiber optic cable assembly as claimed in claim 2, wherein the end portion of the jacket defines a bore adapted to receive the connector end of the connector assembly.

6. A fiber optic cable assembly as claimed in claim 5, wherein the connector end includes a plurality of flared portions for retaining the connector end in the bore of the jacket.

7. A fiber optic cable assembly as claimed in claim 6, further comprising a crimp disposed along the texturized surface of the jacket, wherein the texturized surface assists in the retention of the crimp when the crimp is in tight engagement with the jacket.

8. A fiber optic cable assembly as claimed in claim 1, wherein the connector end is a selectively deformable structure that defines an inner cavity adapted to receive the jacket.

9. A fiber optic cable assembly as claimed in claim 1, wherein the connector assembly is mechanically swaged to the jacket.

10. A fiber optic cable assembly as claimed in claim 1, wherein the connector assembly is ultrasonically swaged to the jacket.

11. A fiber optic cable assembly as claimed in claim 1, wherein the connector assembly is thermally welded to the jacket.

12. A fiber optic cable assembly as claimed in claim 1, wherein the connector assembly is secured to the jacket using a coating and a UV-curing process.

13. A fiber optic cable assembly as claimed in claim 1, wherein the reinforcement members include aramid yarn.

14. A fiber optic cable assembly as claimed in claim 1, wherein the reinforcement members make up about 40% to about 70% of a total weight of the jacket.

15. A fiber optic cable assembly as claimed in claim 1, wherein lengths of the reinforcement members are no more than about 3.2 mm.

16. A fiber optic cable assembly as claimed in claim 1, wherein diameters of the reinforcement members are no more than about 100 μ

m.

17. A fiber optic cable assembly as claimed in claim 1, wherein the end portion of the jacket is disposed within the connector end of the connector assembly.
