Abstract
An electrical connector system includes first and second connector assemblies. Each connector assembly includes contacts arranged in at least two differential pairs wherein one of the pairs is an aggressor pair and one of the pairs is a victim pair. A differential signal carried by the aggressor pair generates far end crosstalk on the victim pair. The contacts are arranged such that, when the first and second connector assemblies are electrically connected to each other, the far end crosstalk on the victim pair in the first connector assembly has a magnitude and a polarity, and the far end crosstalk on the victim pair in the second connector assembly has the same magnitude and an opposite polarity.
Claims15
An electrical connector comprising:
- a housing having a mating face and a mounting face, the housing holding signal contacts and ground contacts arranged in rows, each of said signal contacts and ground contacts including a mating end extending from said mating face of said housing and a mounting end extending from said mounting face of said housing, wherein said signal contacts are arranged in alternating pairs of straight signal contacts and offset signal contacts, structure of said pair of straight signal contacts are different from said pair of offset signal contacts, and wherein for each said row, said mounting ends of said ground contacts and said straight signal contacts are arranged along a centerline of said row and said mounting ends of said offset signal contacts in each pair of offset signal contacts are offset on opposite sides of said centerline.
An orthogonal connector assembly including a pair of connectors configured to be electrically connected to one another from opposite sides of a circuit board, said electrical connector assembly comprising:
- first and second connector housings, each having a mating face and a mounting face, said mounting faces being configured to be electrically connected to one another from opposite sides of the circuit board in line with one another along a longitudinal axis, and wherein said first and second connector housings are angularly offset ninety degrees about said longitudinal axis with respect to one another;
- and
- signal and ground contacts held in said connector housings and arranged in rows, each said signal contact and ground contact including a mating end and a mounting end, and wherein said signal contacts include pairs of straight signal contacts and offset signal contacts, and wherein mated pairs of said offset signal contacts on opposite sides of the circuit board are arranged about a common axis and wherein said mated pairs are rotated one hundred eighty degrees with respect to one another about said axis.
