Communications Patching and Connector Systems Having Multi-Stage Near-End Alien Crosstalk Compensation Circuits

A communications connector system, comprising:

• a first communications connector that includes a first output contact and a second output contact, the first and second output contacts being connected to respective first and second input contacts via respective first and second conductive paths through the first communications connector, the first and second output contacts, input contacts and conductive paths forming a first differential pair of communications paths through the first communications connector;
• a second communications connector that includes a third output contact and a fourth output contact, the third and fourth output contacts being connected to respective third and fourth input contacts via respective third and fourth conductive paths through the second communications connector, the third and fourth output contacts, input contacts and conductive paths forming a second differential pair of communications paths through the second communications connector;
• a third communications connector that includes a fifth output contact and a sixth output contact, the fifth and sixth output contacts being connected to respective fifth and sixth input contacts via respective fifth and sixth conductive paths through the third communications connector, the fifth and sixth output contacts, input contacts and conductive paths forming a third differential pair of communications paths through the third communications connector;
• a first near-end alien crosstalk compensation circuit that is configured to compensate for near-end alien crosstalk between the first differential pair of communications paths and the second differential pair of communications paths;
• and
• a second near-end alien crosstalk compensation circuit that is configured to compensate for near-end alien crosstalk between the first differential pair of communications paths and the third differential pair of communications paths.
