Abstract

Embodiments of the present invention generally relate to the field of electronic communication, and more particularly, to techniques used to compensate for/reduce/or otherwise manipulate crosstalk in communication connectors, and apparatuses and methods which employ such techniques. In an embodiment, the present invention is a communication connector that includes a plurality of signal pairs including at least a first pair and a second pair, a first compensation stage between the first pair and the second pair, and an orthogonal compensation network between the first pair and the second pair. The orthogonal compensation network can be time delayed from the first compensation stage.

Claims

1. A method for tuning a communication plug, said plug adapted for use with a communication jack, said plug producing a predefined amount of offending crosstalk that is substantially cancelled within said communication jack, said method comprising the steps of:

producing a first differential pair of conductors;

producing a second differential pair of conductors; and

positioning a first R-L-C circuit between a first conductor of said first differential pair of conductors and a first conductor of said second differential pair of conductors to produce a first offering crosstalk, said first R-L-C circuit including a first resistor, a first inductor, and a first capacitor connected to each other in series, said a first capacitor having a capacitance value selected to produce a predefined amount of first capacitive crosstalk, said first inductor having an inductance value selected to produce, in combination with said first capacitor, a predefined first resonant frequency, and said first resistor having a resistance value selected to produce a predefined first peak level of a frequency response of said first R-L-C circuit, said first peak level occurring at said first resonant frequency.

2. The method of claim 1, further comprising the steps of:

positioning a second R-L-C circuit between a second conductor of said first differential pair of conductors and a second conductor of said second differential pair of conductors to produce a second offering crosstalk, said second R-L-C circuit including a second resistor, a second inductor, and a second capacitor connected to each other in series, said a second capacitor having a capacitance value selected to produce a predefined amount of second capacitive crosstalk, said second inductor having an inductance value selected to produce, in combination with said second capacitor, a predefined second resonant frequency, and said second resistor having a resistance value selected to produce a predefined second peak level of a frequency response of said second R-L-C circuit, said second peak level occurring at said second resonant frequency.

3. The method of claim 2, wherein said first R-L-C circuit is balanced with respect to said second R-L-C circuit.

4. The method of claim 1, wherein said communication plug is tuned to be backwards compatible with at least one of a Category 6 standard and a Category 6A standard.
