ABSTRACT:
A communication jack has a housing with a face having a plug receiving aperture. A plurality of conductive path pairs extends from corresponding plug interface contacts located at the plug receiving aperture to corresponding output terminals. A first circuit board is connected to the plug interface contacts and a second circuit board is connected to the plug interface contacts and the output terminals. The first circuit board has a first single stage of crosstalk compensation with opposite polarity of the crosstalk of a plug for a first combination of the conductive path pairs. The second circuit board includes a second single stage of opposite polarity crosstalk compensation for some of the conductive path pairs not compensated on the first circuit board. The stages cancel substantially all of the crosstalk caused by the plug, for the signal operating frequencies, for corresponding combinations of the conductive path pairs.
