Abstract

A connector includes a wafer having first, second, third, and fourth communication channels. The first and second communication channels form a first differential pair, and the third and fourth communication channels form a second differential pair. The wafer includes a plug and a receptacle. The plug includes a first portion of the first, second, third, and fourth communication channels. The receptacle includes a second portion of the first, second, third, and fourth communication channels. A first crisscross is located at a first predetermined location of the first and second communication channels of the first differential pair. The first crisscross changes a first polarity of a first signal to be transmitted on the first differential pair. A second polarity of a second signal to be transmitted on the second differential pair remains the same throughout an entire length of the second differential pair.
