Communication connector with improved crosstalk compensation

A communication system for connection to at least one communication plug over a range of signal operating frequencies, the communication plug having a source of crosstalk, said communication system comprising:

• electrical equipment having at least one jack receiving aperture;
• a communication jack connected to said electrical equipment at said jack receiving aperture, said communication jack including a housing having a first face with a plug receiving aperture therein;
• a plurality of conductive path pairs extending from corresponding plug interface contacts located at said plug receiving aperture to corresponding output terminals, said plurality of conductive path pairs including a first circuit board connected to said plug interface contacts and a second circuit board connected to said plug interface contacts and said output terminals, said first circuit board including a first single stage of crosstalk compensation with opposite polarity of the crosstalk of the plug for at least a first combination of said conductive path pairs, said second circuit board including a second single stage of crosstalk compensation with opposite polarity of the crosstalk of the plug for at least some of said conductive path pairs not compensated on said first circuit board, wherein said stages cancel substantially all of the crosstalk caused by the plug, for all of the signal operating frequencies, for corresponding combinations of said plurality of conductive path pairs;
• wherein said first circuit board comprises a flexible circuit board.

A communication jack for compensating for a source of near-end crosstalk in a mated communication plug over a range of signal operating frequencies, the mated plug including a plurality of plug contacts, comprising:

• a housing having a first face with a plug receiving aperture therein;
• a plurality of conductive path pairs directly extending from corresponding plug interface contacts located at said plug receiving aperture to corresponding output terminals, said plurality of conductive path pairs including a circuit board connected to said plug interface contacts beyond where the plug contacts engage said plug interface contacts, said circuit board being a flexible circuit board, not in direct contact with said output terminals, said circuit board including a single stage of crosstalk compensation with opposite polarity of the crosstalk of the plug for at least one combination of said conductive path pairs, wherein said single stage of crosstalk compensation cancels substantially all of the near-end crosstalk caused by the plug, over the range of signal operating frequencies, for said at least one combination of said conductive path pairs, said plug interface contacts including a plug contact point approximately where the plug contacts engage said plug interface contacts, said single stage of crosstalk compensation being located a physical distance from said plug contact point and along said plurality of conductive path pairs, and said single stage of crosstalk providing compensation approximately equivalent to a maximum of 3.0 degrees of electrical phase of the signal at the highest frequency in the range of signal operating frequencies.
