1. 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.

Abstract
A communication connector uses compensation circuitry to compensate for crosstalk in a network connection. Portions of the compensation circuitry are placed on a flexible circuit board that makes conductive contact with plug interface contacts of the connector. Additional compensation circuitry is provided on a rigid circuit board within the connector.
