Abstract:
1. A communications connector system, comprising: a first communications connector that includes a first output terminal and a second output terminal, the first and second output terminals being connected to respective first and second conductive paths through the first communications connector, the first and second conductive paths forming a first differential pair of conductive paths through the first communications connector; a second communications connector that includes a third output terminal and a fourth output terminal, the third and fourth output terminals being connected to respective third and fourth conductive paths through the second communications connector, the third and fourth conductive paths forming a second differential pair of conductive paths through the second communications connector, the second communications connector being immediately adjacent to the first communications connector and arranged such that a first signal coupling level from the first output terminal to the third output terminal in response to a first communication signal that is transmitted through the first differential pair of conductive paths exceeds a second signal coupling level from the first output terminal to the fourth output terminal in response to the first communication signal; and a multi-stage near-end alien crosstalk compensation circuit having at least a first stage and a second stage that is configured to compensate for near-end alien crosstalk between the first and second differential pairs of conductive paths, wherein the polarity of the near-end alien crosstalk introduced in the first stage is generally opposite the polarity of the near-end alien crosstalk introduced in the second stage and is also generally opposite the polarity of the near-end alien crosstalk introduced in the first through fourth output terminals.
