Patent ID: 7787615

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; and a crosstalk compensation arrangement that provides crosstalk compensation between selected tracks of the circuit board, the selected tracks including two pairs of tracks, wherein tracks of each pair diverge from one another as the tracks extend from their corresponding contact spring to their corresponding wire termination contacts, the selected tracks also having high impedance portions with impedances greater than 100 ohms; wherein capacitive couplings are provided between the tracks of each pair at a position located between the crosstalk compensation arrangement and the wire termination contacts, the capacitive couplings being positioned far enough away from the crosstalk compensation arrangement to reduce return loss of the selected tracks at least for signal frequencies in the range of 200-500 MHz.
