Abstract

An electrical connector system, comprising: an electrical connector; a plurality of wires extending from the connector and arranged in a plurality of twisted pairs; and an insert separating the wires defining each of the twisted pairs. A method of reducing cross-talk in an electrical connector system that produces an unwanted cross-talk, comprising the steps of: providing an electrical connector with a plurality of wires extending therefrom and arranged in a plurality of twisted pairs; providing an insert; placing the insert between the wires defining each of the twisted pairs. The insert causes the wires to produce a compensating cross-talk that offsets the unwanted cross-talk. A method of using an electrical connector that exhibits an acceptable level of cross-talk within a desired frequency range, comprising the steps of: providing an electrical connector system that is unable to exhibit the acceptable level of cross-talk within the desired frequency range, the system including: an electrical connector; and a plurality of wires extending from the connector and arranged in a plurality of twisted pairs; separating the wires defining each of the twisted pairs; and operating the connector system within the desired frequency range. As a result, the connector system exhibits the desired level of cross-talk.

Claims

1. An electrical connector system, comprising:

an electrical connector, said electrical connector creating a first cross-talk;

first and second twisted pairs of wires extending from said connector; and

a dielectric insert comprising first and second opposed surfaces;

wherein a first wire of said first twisted pair and a first wire of said second twisted pair correspond to a first surface of said insert and a second wire of said first twisted pair and second wire of said second twisted pair correspond to said second surface of said insert such that the wiring contributes towards creating a compensating cross-talk to said first cross-talk.

2. The electrical connector system according to claim 1, wherein said insert has a predetermined length, said predetermined length contributes towards creating said compensating cross-talk.

3. The electrical connector system according to claim 2, wherein said insert separates said wires to a predetermined spacing, said predetermined spacing further contributing towards creating said compensating cross-talk.

4. The electrical connector system according to claim 3, wherein said compensating cross-talk is substantially equal to said first cross-talk.

5. A method of substantially reducing the cross-talk in a connector, comprising the steps of:

providing an pre-constructed electrical connector system having an electrical connector with at least first and second twisted pairs of wires, each wire of said twisted pairs of wires terminated to a contact and extending from the connector;

providing an insert having first and second opposed surfaces;

placing a first wire of said first twisted pair and a first wire of said second twisted pair adjacent said first surface of said insert and a second wire of said first twisted pair and second wire of said second twisted pair adjacent said second surface of said insert.
