High-speed connector with multi-stage compensation

A communication jack for use in a communication network, said jack having a plurality of plug interface contacts for making conductive contact with contacts of a plug, said communication jack comprising:

• eight current-carrying paths through the communication jack, said current-carrying paths comprising first, second, third, and fourth differential pairs of conductors, each of said differential pairs comprising a first and a second conductive pathway;
• compensation circuitry adapted to decrease the overall crosstalk when said communication jack is connected to a plug, said compensation circuitry comprising:
• 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 first conductive pathway of the second differential pair and the first conductive pathway of the fourth differential pair;
• and
• a fourth capacitor connected between the second conductive pathway of the second differential pair and the second conductive pathway of the third differential pair;
• wherein said first, second, third, and fourth capacitors are provided on a flexible circuit board in electrical contact with said plug interface contacts and further are provided within a single stage of compensation in said jack;
• and
• wherein the jack further comprises a rigid circuit board containing compensation circuitry wherein the compensation circuitry comprises second stage lattice network crosstalk between the first and second differential pairs.
