Abstract
The present invention generally relates to the field of network communication, and more specifically to networks for crosstalk reduction/compensation and communication connectors which employ such networks. In some embodiments, the present invention employs an orthogonal network implemented within a communication jack to compensate for crosstalk which occurs within a communication plug and at the plug/jack interface.
