Abstract

An optically traceable patch cord includes a cable extending from a first connector at a first end to a second connector at a second end. A trace assembly in the cable is located between the first end of the cable and the second end of the cable. An optical tracing fiber extends from the trace assembly to one of the first connector and the second connector.

First claim

What is claimed is:

1. An optical traceable patch cord, comprising:
a cable extending from a first connector at a first end to a second connector at a second end;
a trace assembly provided in the cable between the first end of the cable and the second end of the cable and spaced from each of the first connector and the second connector, the trace assembly comprising a connection sleeve surrounding the cable and crimped to an interface housing; and
an optical fiber extending from the trace assembly towards the second end of the cable.

2. The optical traceable patch cord of claim 1 , wherein the trace assembly comprises an optical receptacle, the optical fiber extending from the optical receptacle towards the second end of the cable, the optical receptacle configured to connect to a light source.

3. The optical traceable patch cord of claim 2 , further comprising an alignment sleeve encapsulating the optical receptacle.

4. The optical traceable patch cord of claim 3 , wherein the alignment sleeve comprises a spring steel material.

5. The optical traceable patch cord of claim 2 , wherein the optical receptacle comprises a ferrule fixedly mounted within the interface housing.

6. The optical traceable patch cord of claim 2 , wherein the optical receptacle is configured to connect to the light source at an end of the optical receptacle, further comprising a cap configured to selectively cover the end of the optical receptacle configured to connect to the light source.

7. The optical traceable patch cord of claim 6 , wherein the cap is rotatably mounted to the trace assembly, whereby the cap is selectively rotatable between an open position for providing access to the optical receptacle and a closed position wherein the cap covers the end of the optical receptacle.

8. The optical traceable patch cord of claim 2 , wherein the cable extends along a first direction through the trace assembly and the optical receptacle is oriented along a second direction oblique to the first direction.

9. The optical traceable patch cord of claim 1 , wherein the trace assembly is a first trace assembly, further comprising a second trace assembly provided in the cable and spaced from each of the first connector and the second connector, the optical fiber extending from the first trace assembly to the second trace assembly.

10. The optical traceable patch cord of claim 1 , wherein the interface housing comprises a first half and a second half, the interface housing comprising a protrusion at the first half and a mating recess at the second half, the protrusion configured to join into the mating recess to join the halves together.

11. A method of tracing a patch cord, the patch cord comprising a cable extending from a first connector to a second connector, the method comprising:
emitting light into an optical tracing fiber at a trace assembly in the patch cord, the trace assembly spaced from each of the first connector and the second connector and comprising a connection sleeve surrounding the cable and crimped to an interface housing and
transmitting the light through the optical tracing fiber towards the second connector.

12. The method of claim 11 , wherein the trace assembly is a first trace assembly, the step of transmitting the light comprises transmitting the light to a second trace assembly spaced from each of the first connector and the second connector and proximate the second connector, and the method further comprises detecting the light at the second trace assembly.

13. The method of claim 11 , wherein the trace assembly comprises an optical receptacle, the optical tracing fiber is connected to the optical receptacle, and wherein the method further comprises connecting a light source to the optical receptacle and the step of emitting light comprises emitting light from the light source connected to the optical receptacle into the optical tracing fiber.

14. The method of claim 13 , further comprising aligning the light source with the optical receptacle through an alignment sleeve encapsulating the optical receptacle prior to connecting the light source to the optical receptacle.

15. The method of claim 14 , wherein the alignment sleeve comprises a spring steel material, and wherein the step of aligning comprises biasing the alignment sleeve with the light source.

16. The method of claim 13 , further comprising removing a protective cap from an end of the optical receptacle prior to connecting the light source to the optical receptacle, wherein the step of connecting the light source to the optical receptacle comprises connecting the light source to the end of the optical receptacle.

17. The method of claim 16 , wherein the step of removing the protective cap comprises rotating the protective cap.

18. The method of claim 17 , wherein the step of removing the protective cap further comprises rotating the protective cap about the interface housing.

19. The method of claim 11 , the method comprising:
coupling a first half and a second half of the interface housing to the cable via a protrusion at the first half configured to join a mating recess at the second half.
