Communication plug with improved crosstalk
First Claim
1. A communication plug comprising:
- a housing;
a printed circuit board (PCB) positioned at least partially inside said housing;
a plurality of cable contacts;
a plurality of connector contacts attached to the PCB, comprising;
a first connector contact and a second connector contact adjacent to the first connector contact, the first and second connector contacts forming a second contact pair;
a seventh connector contact and an eighth connector contact adjacent to the seventh connector contact, the seventh and eighth connector contacts forming a fourth contact pair;
a third connector contact disposed between the second and the seventh connector contact, and adjacent to the second connector contact;
a sixth connector contact disposed between the third and seventh connector contact, and adjacent to the seventh connector contact, the second and sixth connector contacts forming a third contact pair;
a fourth connector contact disposed between the third and the sixth connector contact, and adiacent to the third connector contact; and
a fifth connector contact disposed between, and adiacent to, the fourth and sixth connector contacts, the fourth and fifth connector contacts forming a first connector pair;
a first capacitor connecting the first connector contact to the sixth connector contact to introduce mirrored capacitive crosstalk between the third connector pair and the second connector pair; and
a second capacitor connecting the first connector contact to the fifth connector contact to introduce mirrored capacitive crosstalk between the first connector pair and the second connector pair.

Abstract
A communication plug having a plug body and a plurality of contact pairs at least partially within the plug body, the contact pairs including an inherent asymmetric coupling between individual contacts of one of the contact pairs and other individual contacts of another of the contact pairs. Second asymmetric coupling elements are connected between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. The second asymmetric coupling elements, when combined with the inherent asymmetric coupling, provide a balanced symmetric coupling between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs.
