Patent ID: 7381098

Claim:
A telecommunications jack for use in a twisted pair system, the telecommunications jack comprising: a housing defining a port for receiving a plug; a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing; a plurality of wire termination contacts for terminating wires to the jack; a circuit board including conductive tracks that electrically connect the contact springs to the wire termination contacts, wherein the contact springs extend outwardly from a first side face of the circuit board and the wire termination contacts extend outwardly from a second side face of the circuit board, the contact springs and the first side face being opposite with the wire termination contacts and the second side face; and a crosstalk compensation arrangement that provides crosstalk compensation between selected tracks of the circuit board, the crosstalk compensation arrangement including a first zone of compensation that is positioned a first time delay away from a source of crosstalk located at the plug, the crosstalk compensation arrangement also including a second zone of compensation that is positioned a second time delay away from the first zone of compensation, the crosstalk compensation arrangement further including a third zone of compensation that is positioned a third time delay away from the second zone of compensation, the first and third time delays being generally equal to one another, and the second time delay being different from the first and third time delays; wherein the first zone of compensation has a first capacitance having an opposite polarity and at least about three times the magnitude as compared to a capacitance of the source of crosstalk at the plug, wherein the second zone of compensation has a second capacitance having about the same magnitude but an opposite polarity as compared to the first capacitance, wherein the third zone of compensation has a third capacitance having an opposite polarity and about the same magnitude as compared to the capacitance at the source of crosstalk at the plug, and wherein the second time delay is greater than the first and third time delays.
