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 (a−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.
Claims9
An electrical connector for providing predetermined amounts of compensating signals for approximately canceling a like amount of an offending signal at a given frequency, the connector having a plurality of pairs of metallic conductors forming an interconnection path between input and output terminals of the connector, at least some of the pairs being adjacent each other, the connector further including a first compensation stage at a first location along the interconnection path wherein compensating signals having a first magnitude and polarity are coupled between the pairs and second compensation stage at a second location along the interconnection path wherein compensating signals having a second magnitude and polarity are coupled between the pairs;
- at least a third compensation stage at a third location along the interconnection path wherein compensating signals having a third magnitude and polarity are coupled between the pairs;
- wherein the magnitudes and polarities of the compensating signal in the several stages are given by the algorithm:
- (a−b)n
- where the values and signs of the coefficients of the expanded algorithm determine the magnitudes and polarities of compensating the signals in the stages and wherein n is equal to the member of compensation for values of n≧3.
