Abstract

A traceable cable assembly includes a traceable cable having at least one data transmission element, a jacket at least partially surrounding the at least one data transmission element, and a tracing optical fiber incorporated with and extending along at least a portion of a length of the traceable cable. The traceable cable assembly also includes a connector provided at each end of the traceable cable. Each connector has a connector housing having opposed first and second ends, the second end being coupled to the traceable cable, and a diffuser supported by the connector housing. The connector housing is configured to receive tracer light from the tracing optical fiber and allow the tracer light to leave the connector housing. The diffuser is also configured to diffuse the tracer light leaving the connector housing.

Claims

1. A traceable cable assembly, comprising:

a traceable cable, comprising;

at least one data transmission element,

a jacket at least partially surrounding the at least one data transmission element, and

a tracing optical fiber incorporated with and extending along at least a portion of a length of the traceable cable; and

a connector provided at each end of the traceable cable, each connector comprising;

a connector housing having opposed first and second ends the second end being coupled to the traceable cable; and

a diffuser supported by the connector housing, wherein the connector housing is configured to receive tracer light from the tracing optical fiber and allow the tracer light to leave the connector housing, and further wherein the diffuser is configured to diffuse the tracer light leaving the connector housing, wherein the diffuser is fixed to the connector housing and configured to permit tracer light to be delivered into the connector to the tracing optical fiber.

3. The traceable cable assembly of claim 1, wherein the diffuser comprises a front face oriented away from the connector housing and a diffusive emission surface recessed from the front face.

4. The traceable cable assembly of claim 1, wherein the diffuser is movable relative to the connector housing such that the connector is configured to accept tracer light that bypasses the diffuser.

5. The traceable cable assembly of claim 4, wherein the diffuser is configured to pivot into the connector housing.

6. The traceable cable assembly of claim 1, wherein the diffuser comprises an array of diffusive protrusions.

7. The traceable cable assembly of claim 6, wherein the diffuser further comprises a central region, and wherein the array of diffusive protrusions extend at least partially around the central region.

8. The traceable cable assembly of claim 1, wherein the connector housing includes a path for routing the tracer optical fiber to the diffuser, and further wherein the tracing optical fiber is looped one or more times in the path.

9. The traceable cable assembly of claim 1, wherein the connector further comprises an expanded beam connector supported by the connector housing, wherein the expanded beam connector is configured to converge or collimate the tracer light into the tracing optical fiber.

2. (canceled)

10. A traceable cable system, comprising:

a traceable cable, comprising;

at least one data transmission element,

a jacket at least partially surrounding the at least one data transmission element, and

a tracing optical fiber incorporated with and extending along at least a portion of a length of the traceable cable;

a connector provided at each end of the traceable cable, each connector comprising;

a connector housing having opposed first and second ends, the second end being coupled to the traceable cable, and

a diffuser supported by the connector housing; and

a launch tool, comprising;

a light source configured to produce tracer light, and

a waveguide having opposite receiving and emissions ends, wherein the receiving end is in optical communication with the light source,

wherein;

the launch tool is configured to at least indirectly provide tracer light to the tracing optical fiber proximate one end of the traceable cable;

the connector housing coupled to an opposite end of the traceable cable is configured to receive the tracer light from the tracing optical fiber and allow the tracer light to leave the connector housing; and

the diffuser is configured to diffuse the tracer light leaving the connector housing such that the tracer light is visible proximate the opposite end of the traceable cable, wherein the diffuser is fixed to the connector housing such that the diffuser permits tracer light to be delivered into the connector to the tracing optical fiber from the launch tool.

12. The traceable cable system of claim 10, wherein the diffuser comprises an array of diffusive protrusions, and wherein the emission end of the waveguide comprises an emission face complimentary to the array of diffusive protrusions.

13. The traceable cable system of claim 10, wherein the emission end of the waveguide comprises a compliant material index-matched to the diffuser, and

wherein the compliant material is configured to abut the diffuser to minimize any air gaps therebetween.

14. The traceable cable system of claim 10, wherein the diffuser comprises a front face oriented away from the connector housing and a diffusive emission surface recessed from the front face, and further wherein a plurality of guide walls of the diffuser form a cavity at least partially around the diffusive emission surface.

15. The traceable cable system of claim 14, wherein the emission end of the waveguide of the launch tool is configured to fit within the cavity.

16. The traceable cable system of claim 10, wherein the diffuser comprises an array of diffusive protrusions.

17. The traceable cable system of claim 16, wherein the diffuser further comprises a central region, and wherein the array of diffusive protrusions extend at least partially around the central region.

18. The traceable cable system of claim 10, wherein the diffuser is movable relative to the connector housing such that the tracer light provided by the launch tool can reach the tracing optical fiber without passing through the diffuser.

19. The traceable cable system of claim 18, wherein the diffuser is configured to pivot into the connector housing when a portion of the launch tool engages the diffuser and extends into the connector housing.

20. The traceable cable system of claim 10, wherein the connector housing comprises a first fastening portion and the waveguide comprises a second fastening portion, the second fastening portion being configured to mate with the first fastening portion, and

wherein mating the first fastening portion to the second fastening portion substantially aligns the emission end of the waveguide with the connector.

21. The traceable cable system of claim 10, wherein the connector housing includes a path for routing the tracer optical fiber to the diffuser, and further wherein the tracing optical fiber is looped one or more times in the path.

22. The traceable cable system of claim 10, wherein the connector further comprises an expanded beam connector supported by the connector housing, wherein the expanded beam connector is configured to converge or collimate the tracer light from the launch tool into the tracing optical fiber.

11. (canceled)

23. A traceable cable assembly, comprising:

a traceable cable, comprising;

at least one data transmission element,

a jacket at least partially surrounding the at least one data transmission element, and

a tracing optical fiber incorporated with and extending along at least a portion of a length of the traceable cable; and

a connector provided at each end of the traceable cable, each connector comprising;

a connector housing having opposed first and second ends, the second end being coupled to the traceable cable, and

a diffuser supported by the connector housing; and

wherein;

the connector housing includes a path that directs the tracer optical fiber from the traceable cable to the diffuser;
