1. A method of compensating for crosstalk in a modular communication connector comprising a plug and a jack, the jack comprising a plurality of jack contacts and a plurality of insulation displacement connectors (IDCs) configured to connect to wires of a cable, each jack contact having an interface at which the plug, when inserted into the jack, contacts the jack contact, the method comprising:
- connecting a flexible printed circuit (FPC) to the jack contacts such that a first end of the FPC is connected to each jack contact approximately adjacent to and on an opposite side from the interface; and
connecting a second end of the FPC to the IDCs, the FPC providing a network path for at least two conductor pairs between the jack contacts and the IDCs wherein the network path comprises conductive traces that provide crosstalk compensation and include a Near End (NEXT) compensation zone, a Near End (NEXT) crosstalk zone, a first transition zone between the jack contacts and the NEXT compensation zone, and a second transition zone between the NEXT compensation zone and the NEXT crosstalk zone, and the NEXT compensation zone is approximately equal in length to the NEXT crosstalk zone.
