Abstract

Both differential mode-to-differential mode crosstalk compensation and differential-to-common (or common mode-to-differential mode) crosstalk compensation are realized by using a pattern of conductor crossovers in a multi-pair electrical connector dictated by the algorithm (.alpha.-b)n with n >= 3, where n determines the number of compensating stages and the coefficients of the expanded algorithm in each stage. An electrical connector with a pattern of conductors fashioned with these constraints among several of the pairs of conductors.
