Patent ID: 8287317

Claim:
A communication jack for use in a communication network, the jack having a plurality of plug interface contacts for making conductive contact with contacts of a plug, the communication jack comprising: eight current-carrying paths through the communication jack, the current-carrying paths comprising first, second, third, and fourth differential pairs of conductors, each of the differential pairs comprising a first and a second conductive pathway; compensation circuitry adapted to decrease an overall crosstalk when the communication jack is connected to a plug, the compensation circuitry including: a first capacitor connected between the first conductive pathway of the first differential pair and the second conductive pathway of the second differential pair; a second capacitor connected between the second conductive pathway of the first differential pair and the first conductive pathway of the second differential pair; a third capacitor connected between the second differential pair and the fourth differential pair; and a fourth capacitor connected between the second differential pair and the third differential pair; wherein the first, second, third, and fourth capacitors are provided on a flexible circuit board in electrical contact with the plug interface contacts; and wherein the jack further includes a rigid circuit board containing compensation circuitry having a frequency-dependent crosstalk between the first and second differential pairs wherein a magnitude of the frequency dependent crosstalk varies at a rate with frequency different than a magnitude of crosstalk provided by the first capacitor and the second capacitor.
