Abstract
Abstract A link cable assembly is provided as an interface between a network cable test instrument and a network to be tested. The link cable assembly includes a link cable that is constructed to minimize cross talk and have long-term high quality reliability. Interchangeable connector personality modules releasably attached to the link cable permit testing networks having different electrical characteristics. Calibration data may be stored within the cable assembly to allow intrinsic “patch cord” return loss to be factored out of network cable measurements.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
A cable assembly, comprising: a plurality of differential pair cables arranged in juxtaposition relationship to form a flat link cable having a first end and a second end; and an outer sheath of insulating material formed around said plurality of differential pair cables, each of said plurality of differential pair cables comprising two wires arranged in juxtaposition relationship and disposed in an individual dielectric medium which embeds said two wires of only one of said plurality of differential pair cables in constant spatial relationship over a length, and a metallic shield disposed around an outer surface of each of said individual dielectric medium.
Claim 2
Dependent Claim
103 words
A cable assembly, comprising: a plurality of differential pair cables arranged in juxtaposition relationship to form a flat link cable having a first end and a second end; and an outer sheath of insulating material formed around said plurality of differential pair cables, each of said plurality of differential pair cables comprising two wires arranged in juxtaposition relationship and disposed in an individual dielectric medium which embeds said two wires of only one of said plurality of differential pair cables in constant spatial relationship over a length, and a metallic shield disposed around an outer surface of each of said individual dielectric medium.
Claim 3
Dependent Claim
72 words
A cable assembly in accordance with claim 1 wherein said metallic shield comprises a first shield formed by wrapping a tape having at least one metallic surface in a first direction around each of said individual dielectric medium, and a second shield formed by wrapping said tape having at least one metallic surface in a second direction around said first shield such that said metallic surfaces are in contact with each other.
Claim 4
Dependent Claim
29 words
A cable assembly in accordance with claim 2 further comprising a drain wire disposed between said first shield and said second shield in electrical contact with said metallic surfaces.
Claim 5
Dependent Claim
24 words
A cable assembly in accordance with claim 2 further comprising a third shield of magnetic material disposed outside of said first and second shield.
Claim 6
Dependent Claim
36 words
A cable assembly in accordance with claim 1 further comprising an interface adapter electrically connected to said first end of said link cable, said interface adapter including a connector for connecting with a cable test instrument.
Claim 7
Dependent Claim
28 words
A cable assembly in accordance with claim 5 wherein said interface adapter also includes a memory containing calibration data relating to intrinsic return loss in said link cable.
Claim 8
Dependent Claim
35 words
A cable assembly in accordance with claim 1 further comprising a personality module electrically connected to said second end of said link cable, said personality module having a connector for connecting with a network port.
Claim 9
Dependent Claim
23 words
A cable assembly in accordance with claim 7 wherein said personality module is releasably attached to said second end of said link cable.
Claim 10
Dependent Claim
30 words
A cable assembly in accordance with claim 8 wherein said personality module is one of a plurality of interchangeable personality modules each having characteristics to match a specific network port.
Claim 11
Dependent Claim
70 words
A cable assembly in accordance with claim 9 wherein said personality module includes a memory device containing stored information relating to said network connector, and wherein said link cable further includes a data cable extending along said plurality of differential pair cables with one end of said data cable electrically connectible to said memory device and the other end of said data cable electrically connectible to a cable test instrument.
