Patent Images
1. A jack for use in a plug-jack combination in a communication system, said jack comprising:
- plug interface contacts for making an electrical connection with plug contacts;
a near-end crosstalk zone comprising a first compensation structure providing a first compensation coupling having a first magnitude and a second compensation structure providing a second compensation coupling having a second magnitude, a ratio between said first magnitude and said second magnitude varying with frequency; and
a compensation zone placed between said plug interface contacts and said near-end crosstalk zone in a signal pathway of said jack.

Abstract
A jack is provided that has compensation and crosstalk zones. At least one of the zones employs a lattice network that couples conductors in the zone to reduce the net crosstalk in the plug/jack system. The lattice network has a frequency response slope that is different from the frequency response slope of a first-order coupling or of a series LC circuit coupling. A variety of lattice networks are provided.
