Telecommunications jack with adjustable crosstalk compensation

A crosstalk compensation arrangement for a telecommunications jack comprising:

• a circuit board;
• a plurality of contact springs mounted on the circuit board;
• a plurality of wire termination contacts mounted on the circuit board;
• a plurality of tracks on the circuit board that respectively electrically connect the contact springs to the wire termination contacts;
• and
• a crosstalk compensation arrangement including a zone of crosstalk compensation between a first wire pair and a second wire pair, the zone of crosstalk compensation including a capacitive coupling connected between the first wire pair and the second wire pair and a second capacitive coupling selectively connectable in parallel with the capacitive coupling by altering a connection between a via electrically connected to the capacitive coupling and a via electrically connected to the second capacitive coupling.

A telecommunications jack for use in a twisted pair system, the 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 including a zone of crosstalk compensation between a first wire pair and a second wire pair, the zone of crosstalk compensation including a capacitive coupling connected between the first wire pair and the second wire pair and a second capacitive coupling selectively connectable in parallel with the capacitive coupling by altering a connection between a via electrically connected to the capacitive coupling and a via electrically connected to the second capacitive coupling.
