Abstract

A modular outlet having reduced crosstalk is presented. The modular outlet of the present invention comprises a connector housing which supports a plurality of contacts and a termination cap mated to the housing for terminating a plurality of wires at one end of the contacts. The contacts are positioned on a contact carrier which is received in the housing. The contacts include current carrying plates which are stacked to induce capacitance between selected contacts. This method of achieving a controlled amount of capacitive coupling between selected contacts allows the modular outlet to meet or exceed Category 5 requirements. Further, while the modular outlet connections are positioned in accordance with a standard configuration, the insulation displacement contacts are sequentially positioned, thereby eliminating pair splitting when terminating.
