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, wherein the jacket includes 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;

a connector assembly including a rear housing having a connector end to which an end portion of an outer surface of the jacket is directly anchored;

wherein the end portion includes a texturized surface on the outer surface of the end portion that engages the connector end, the texturized surface having a plurality of external threads; and

wherein the connector end defines a plurality of internal threads that engage the external threads to anchor the outer surface of the end portion to the connector end.

2. A fiber optic cable assembly as claimed in claim 1, wherein the end portion of the jacket defines a bore adapted to receive the connector end of the connector assembly.

3. A fiber optic cable assembly as claimed in claim 2, wherein the connector end includes a plurality of flared portions for retaining the connector end in the bore of the jacket.

4. A fiber optic cable assembly as claimed in claim 3, 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.

5. A fiber optic cable assembly as claimed in claim 1, wherein the jacket surrounding the optical fiber includes about 40% to about 70% by weight of the plurality of reinforcement members integrated into the matrix material of the jacket.

6. A fiber optic cable assembly as claimed in claim 1, wherein the reinforcement members are selected from a group consisting of rods, tendrils, extensions, fibers, and combinations thereof.

7. A fiber optic cable assembly as claimed in claim 1, wherein the reinforcement members have lengths less than 3.2 mm and diameters less than 100 μ

m.

8. A fiber optic cable assembly as claimed in claim 1, wherein a pull-out force required to disengage the connector assembly from the fiber optic cable is at least about twenty-six pounds.
