Abstract

A fiber optic connector and cable assembly is disclosed. The assembly includes a fiber optic connector and a fiber optic cable. The fiber optic cable can be coupled to the assembly at a demarcation section. All components of the fiber optic cable (e.g., fiber, strength members, jacket, etc.) are fixed relative to each other and relative to the fiber optic connector at the demarcation section. The demarcation section may be located on a boot mounted at a proximal end of the fiber optic connector. For example, the demarcation section may be located at a proximal end of the boot. The boot may include an inner passage extending from the demarcation section to the connector, and exterior slots which do not connect to the inner passage.

Claims

1. A fiber optic connector and cable assembly comprising:

a fiber optic connector including a connector body and a boot, the boot being more flexible than the connector body, and the boot having a distal end portion that is coupled to a proximal end portion of the connector body;

a fiber optic cable including an optical fiber, an outer jacket that surrounds the optical fiber, and a tensile reinforcing structure that provides tensile reinforcement to the fiber optic cable, the optical fiber extending through the boot towards the connector body, and the tensile reinforcing structure being anchored relative to the boot at an anchoring location positioned at a proximal half-portion of the boot;

a crimp band for securing the tensile reinforcing structure at the anchoring location on an exterior of the boot;

wherein the boot defines an enclosed inner fiber passage configured to receive the optical fiber extending between the anchoring location and the connector body.

2. The fiber optic connector and cable assembly of claim 1, wherein the connector body is an MPO connector body.

3. The fiber optic connector and cable assembly of claim 1, further comprising a ferrule positioned at the distal end portion of the connector body and a spring that biases the ferrule in a distal direction relative to the connector body, wherein the optical fiber is coupled to the ferrule.

4. The fiber optic connector and cable assembly of claim 3, wherein the connector body is an MPO connector body.

5. The fiber optic connector and cable assembly of claim 1, wherein the boot includes slots extending from the exterior of the boot, and wherein the boot includes an inner core defining the enclosed inner fiber passage not in communication with the slots.

6. The fiber optic connector and cable assembly of claim 1, wherein the fiber optic cable includes a plurality of inner tubes, wherein each inner tube includes a plurality of optical fibers, wherein the tubes terminate at a location past the crimp band and before the connector body.

7. The fiber optic connector and cable assembly of claim 1, wherein the boot includes a snap arrangement for connecting to the connector body.

8. The fiber optic connector and cable assembly of claim 1, wherein the boot includes a plurality of external ridges at the anchoring location.

9. The fiber optic connector and cable assembly of claim 1, wherein the boot tapers in width from the distal end portion to a proximal end portion.

10. A fiber optic connector boot for a fiber optic connector and cable assembly including a fiber optic connector including a connector body and a fiber optic cable including an optical fiber, an outer jacket that surrounds the optical fiber, and a tensile reinforcing structure that provides tensile reinforcement to the fiber optic cable, the optical fiber extending through the boot towards the connector body, and the tensile reinforcing structure being anchored relative to the boot at an anchoring location positioned at a proximal half-portion of the boot, a crimp band for securing the tensile reinforcing structure at the anchoring location on an exterior of the boot;

the fiber optic connector boot comprising;

a boot body, the boot body being more flexible than the connector body, and the boot body having a distal end portion that is coupled to a proximal end portion of the connector body;

wherein the boot body defines an enclosed inner fiber passage configured to receive the optical fiber extending between the anchoring location and the connector body;

wherein the boot body includes slots extending from the exterior of the boot, and wherein the boot body includes an inner core defining the enclosed inner fiber passage not in communication with the slots.

11. The fiber optic connector boot of claim 10, wherein the connector body is an MPO connector body.

12. The fiber optic connector boot of claim 10, further comprising a ferrule positioned at the distal end portion of the connector body and a spring that biases the ferrule in a distal direction relative to the connector body, wherein the optical fiber is coupled to the ferrule.

13. The fiber optic connector boot of claim 12, wherein the connector body is an MPO connector body.

14. The fiber optic connector boot of claim 10, wherein the fiber optic cable includes a plurality of inner tubes, wherein each inner tube includes a plurality of optical fibers, wherein the tubes terminate at a location past the crimp band and before the connector body.

15. The fiber optic connector boot of claim 10, wherein the boot body includes a snap arrangement for connecting to the connector body.

16. The fiber optic connector boot of claim 10, wherein the boot body includes a plurality of external ridges at the anchoring location.

17. The fiber optic connector boot of claim 10, wherein the boot body tapers in width from the distal end portion to a proximal end portion.
