First Claim
Patent Images
1. A communication jack for use in a communication network, the jack comprising:
- a plurality of conductive pathways through the jack, the plurality of pathways comprising at least a first and second signal pair of conductive pathways, each signal pair comprising a first and second conductive pathway;
a first stage of compensation circuitry, the first stage having a first capacitor connected between the second conductive pathway of the first signal pair and the first conductive pathway of the second signal pair and a second capacitor connected between the first conductive pathway of the first signal pair and the second conductive of the second signal pair; and
a second stage of compensation circuitry, the second stage being time delayed and positioned further from a plug/jack interface than the first compensation stage, the second compensation stage having a third capacitor connected between the first conductive pathway of the first signal pair, and the first conductive pathway of the second signal pair, the third capacitor further being positioned between and in series with a first and second inductor.

Abstract
A communication connector uses compensation circuitry to compensate for crosstalk in a network connection. Capacitors are connected between specific conducive paths in said communication connector. Inductive stubs are utilized in the compensation circuitry to improve the overall compensation performance.
