Abstract

An apparatus and method for crosstalk compensation in a jack of a modular communications connector includes connected to the plug interface contacts proximate the plug/jack interface. The structure configured to allow the current to flow generally orthogonal to the plug interface contact.

Claims

1. A communication jack configured to receive a plug to form a communication connection, comprising:

a plurality of jack contacts, the plurality of jack contacts at least partially disposed within a plug receiving cavity in the jack;

a structure attached to at least one of the plurality of jack contacts, the structure connected to the at least one jack contact such as to allow the current to flow generally orthogonal the jack contact,

2. The communication jack of claim 1 wherein the structure is attached to the at least one contact proximate to the plug/jack interface.

3. The communication jack of claim 2 wherein the structure is a flexible printed circuit board connected to the jack contact.

4. The communication jack of claim 2 wherein the structure is a plug interface contact (PIC) cover.
