Abstract

A communications outlet includes eight outlet tines positioned adjacent one another and defining four pairs of outlet tines. The fourth and fifth outlet tines define a first pair, the first and second outlet tines define a second pair, the third and sixth outlet tines define a third pair, and the seventh and eighth outlet tines define a fourth pair. Each outlet tine has a free end near to which a plug contact is adapted to touch and each outlet tine has a fixed end coupled through a corresponding conductive trace to a corresponding conductive wire termination contact. The communications outlet includes a first modal alien crosstalk compensation stage connected to the outlet tines associated with the second, third, and fourth pairs. The first modal alien crosstalk compensation stage includes independent capacitive components operably responsive to differential signals on the third pair to introduce common mode signals onto the second and fourth pairs that have the opposite polarity of common mode signals on the second and fourth pairs at points where the plug contacts connect with the outlet tines.
