Abstract

A communications cabling system adapted for being installed adjacent a first side of a structure having a port communicating with a second side of the structure includes a plurality of unique cable assemblies. Each cable assembly includes a plurality of wires having first and second ends, a first connector having a first plurality of electrical contacts electrically connected to each of the plurality of wires at the first end, a second connector having a second plurality of electrical contacts electrically connected to a first unique subset of the plurality of wires at the second end and a third connector having a third plurality of electrical contacts electrically connected to a second unique subset of the plurality of wires at the second end. At least one of the first, second and third connectors is configured for being supported proximate the port. At least one of the first, second and third connectors includes a portion accessible from the second side. The portion has a unique indicia corresponding to and associated with each unique cable assembly. As a result, the unique indicia indicates at least one of the first and second unique subsets of wires terminating in the second and third connectors, respectively. Preferably, the unique indicia comprises a unique color indicia. In at least one of the first, second and third connectors, a second plurality of electrical contacts are interleaved amongst the first plurality of electrical contacts electrically connected to the plurality of wires. The second plurality of electrical contacts are electrically interconnected to one another.

Claims

1. A communications cabling system comprising:

a set of unique cable assemblies configured to be serially connected to one another, each cable assembly in the set having a different internal structure and external color indicia from all the other cable assemblies to provide each cable assembly with a different function and appearance from all the other cable assemblies, each cable assembly including,

a plurality of wires having first and second ends;

a first connector having a first plurality of electrical contacts electrically connected to each of the plurality of wires at the first end;

a second connector having a second plurality of electrical contacts electrically connected to a first unique subset of the plurality of wires at the second end;

a third connector having a third plurality of electrical contacts electrically coupled to a second unique subset of the plurality of wires at the second end; and

a unique color indicia corresponding to and associated with each unique cable assembly, whereby the color indicia visually indicates at least one of the first and second unique subsets of wires terminating in the second and third connectors, respectively.

2. The cabling system of claim 1 wherein the cable assemblies are configured to be connected together in a serial chain in any order.

3. The cabling system of claim 1 wherein the cable assemblies are configured to be connected together in a serial chain so long as no two cable assemblies in the chain share the same color indicia.

4. The cabling system of claim 1 wherein at least some of the plurality of wires are contained within at least one cable segment.

5. The cabling system of claim 4 including:

a plurality of cable segments; and

a sheath encasing the plurality of cable segments.

6. The cabling system of claim 1 wherein the plurality of wires is arranged in twisted pairs.

7. The cabling system of claim 1 wherein the first connector is of a first gender type and wherein the second and third connectors are of a second gender type.

8. The cabling system of claim 1 wherein the first connector of each of the cable assemblies has a first common color indicia.

9. The cabling system of claim 8 wherein the second connector of each of the cable assemblies has a second common color indicia.

10. The cabling system of claim 9 wherein the third connector of each of the cable assemblies has the unique color indicia.

11. The cabling system of claim 1 wherein the third connector has the unique color indicia.

12. The cabling system of claim 1 wherein the cabling system is configured for being installed adjacent a first side of a structure having a port communicating with a second side of the structure, wherein at least one of the first, second and third connectors is configured for being supported proximate the port and wherein said at least one of the first, second and third connectors includes a portion visually accessible from the second side of the structure, the portion including the unique color indicia.

13. The cabling system of claim 12 wherein the portion projects through the port.

14. The cabling system of claim 13 wherein the portion projects beyond the structure on the second side.

15. The portion of claim 12 wherein the structure includes a surface extending about the portion at the second side, and wherein the portion includes a face extending substantially parallel to the surface, the face including the unique color indicia.

16. The cabling system of claim 12, wherein the unique color indicia is co-molded as part of the portion.

17. A communications cabling system adapted for being installed adjacent a first side of a structure having a port communicating with a second side of the structure, the cabling system comprising:

a set of unique cable assemblies, each cable assembly in the set having a different internal structure and external indicia from all the other cable assemblies to provide each cable assembly with a different function and appearance from all the other cable assemblies, each cable assembly including,

a plurality of wires having first and second ends;

a first connector having a first plurality of electrical contacts electrically connected to each of the plurality of wires at the first end;

a second connector having a second plurality of electrical contacts electrically connected to a first unique subset of the plurality of wires at the second end;

a third connector having a third plurality of electrical contacts electrically connected to a second unique subset of the plurality of wires at the second ends wherein at least one of the first, second and third connectors is configured for being supported proximate the port and wherein said at least one of the first, second and third connectors includes a portion accessible from the second side, the portion having a unique indicia corresponding to and associated with each unique cable assembly, whereby the unique indicia indicates at least one of the first and second unique subsets of wires terminating in the second and third connectors, respectively.

18. The cabling system of claim 17 wherein the portion is visually accessible from the second side.

19. The cabling system of claim 17 wherein the portion projects through the port.

20. The cabling system of claim 19 wherein the portion projects beyond the structure on the second side.

21. The cabling system of claim 17 wherein the structure includes a surface about the port at the second side, and wherein the portion includes a face extending substantially parallel to the surface, the face including the unique indicia.

22. The cabling system of claim 17 wherein the unique indicia comprises a unique color indicia.

23. The cabling system of claim 22 wherein the portion is co-molded with a material having the unique color indicia.
