Abstract

A traceable cable assembly includes a traceable cable having at least one data transmission element, a jacket at least partially surrounding the data transmission element, and first and second tracing optical fibers 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. The first and second tracing optical fibers each have a light launch end and a light emission end. The light launch ends of the first and second tracing optical fibers each include a bend. The bend allows for launching of light into the light launch ends without disengaging the first or second connectors from corresponding connector receptacles.

First claim

We claim:

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;
a first tracing optical fiber extending along at least a portion of a length of the traceable cable, wherein the first tracing optical fiber comprises a light launch end and a light emission end, wherein the light launch end comprises a first bend; and
a second tracing optical fiber extending along the portion of the length of the traceable cable, wherein the second tracing optical fiber comprises a light launch end and a light emission end, wherein the light launch end comprises a second bend;

a first connector provided at a first end of the traceable cable and a second connector provided at a second end of the traceable cable;
wherein the first tracing optical fiber facilitates identification of the second connector when a launch light is injected in the light launch end of the first tracing optical fiber;
wherein the second tracing optical fiber facilitates identification of the first connector when the launch light is injected in the light launch end of the second tracing optical fiber;
wherein the light launch end of the first tracing optical fiber is positioned opposite from the light launch end of the second tracing optical fiber; and
wherein the first bend is located in the first connector and the second bend is located in the second connector.

2. The traceable cable assembly of claim 1 , wherein the light emission end of the first tracing optical fiber is located in the second connector and the light emission end of the second tracing optical fiber is located in the first connector.

3. The traceable cable assembly of claim 1 , wherein the light emission end of the first tracing optical fiber is located near the second connector and the light emission end of the second tracing optical fiber is located near the first connector.

4. The traceable cable assembly of claim 3 , wherein the first tracing optical fiber passes through the second connector and the light emission end of the first tracing optical fiber protrudes outside of the second connector, and wherein the second tracing optical fiber passes through the first connector and the light emission end of the second tracing optical fiber protrudes outside of the first connector.

5. The traceable cable assembly of claim 1 , wherein the light emission end of the first tracing optical fiber comprises a third bend that is equal to or less than 90 degrees.

6. The traceable cable assembly of claim 5 , wherein the light emission end of the second tracing optical fiber comprises a fourth bend that is equal to or less than 90 degrees.

7. The traceable cable assembly of claim 1 , wherein the first tracing optical fiber comprises a core and a cladding, wherein the cladding is removed at the light emission end of the first tracing optical fiber.

8. The traceable cable assembly of claim 1 , wherein the light emission end of the first tracing optical fiber comprises a diffusing element.

9. The traceable cable assembly of claim 8 , wherein the diffusing element is selected from the group comprising a layer of TiO2 impregnated material, a roughened surface, a conical-shaped end, a reflective surface, a refractive surface and a parabolic-shaped end.

10. The traceable cable assembly of claim 1 , wherein the light emission end of the first tracing optical fiber is capable of illuminating at least a portion of the second connector when light is launched into the light launch end of the first tracing optical fiber.

11. The traceable cable assembly of claim 1 , further comprising a launch light tool for emitting light into the first tracing optical fiber or the second tracing optical fiber.

12. The traceable cable assembly of claim 1 , wherein the first bend of the first tracing optical fiber is about 180 degrees to allow for illumination of the light launch end of the first tracing optical fiber when the first connector is engaged in a connector receptacle.

13. The traceable cable assembly of claim 1 , wherein the first bend is equal to or greater than 90 degrees and the second bend is equal to or greater than 90 degrees.

14. The traceable cable assembly of claim 1 , wherein the first bend is the only bend in the first tracing optical fiber and the second bend is the only bend in the second tracing optical fiber.

15. 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;
a first tracing optical fiber extending along at least a portion of a length of the traceable cable, wherein the first tracing optical fiber comprises a light launch end and a light emission end, wherein the light launch end comprises a first bend; and
a second tracing optical fiber extending along the portion of the length of the traceable cable, wherein the second tracing optical fiber comprises a light launch end and a light emission end, wherein the light launch end comprises a second bend;

a first connector provided at a first end of the traceable cable and a second connector provided at a second end of the traceable cable;
wherein the first tracing optical fiber facilitates identification of the second connector when a launch light is injected in the light launch end of the first tracing optical fiber; and
wherein the second tracing optical fiber facilitates identification of the first connector when the launch light is injected in the light launch end of the second tracing optical fiber;
wherein the light launch end of the first tracing optical fiber is positioned opposite from the light launch end of the second tracing optical fiber; and
wherein the first bend is located near the first connector and the second bend is located near the second connector.

16. 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 second tracing optical fiber extending along the portion of the length of the traceable cable, wherein the second tracing optical fiber comprises a light launch end and a light emission end, wherein the light launch end of the second tracing optical fiber comprises a second bend that is equal to or greater than 90 degrees,
wherein the light launch end of the first tracing optical fiber is positioned opposite from the light launch end of the second tracing optical fiber;

a first connector provided at a first end of the traceable cable and a second connector provided at a second end of the traceable cable, wherein the first bend of the first tracing optical fiber is located in the first connector and the second bend of the second tracing optical fiber is located in the second connector;
wherein the first tracing optical fiber facilitates identification of the second connector when a launch light is injected in the light launch end of the first tracing optical fiber; and
wherein the second tracing optical fiber facilitates identification of the firs
