High speed, high density electrical connector

A wafer for an electrical connector, the wafer comprising:

• at least one housing;
• a plurality of first conductors disposed in pairs in a column, each of the first conductors having a first width, the first width being measured along the column;
• and
• a plurality of second conductors disposed in the column, the plurality of first conductors and the plurality of second conductors forming a single column, each of the second conductors adjacent at least one pair of the plurality of first conductors with a portion of the at least one housing disposed between the second conductor and the adjacent pair of first conductors, the conductors of the plurality of second conductors having a second width, the second width being measured along the column, and the second width being greater than the first width.

An electrical connector including a plurality of columns, the electrical connector comprising:

• in each of the plurality of columns:
• a plurality of first conductors disposed in pairs in the column, each of the first conductors having a first width, the first width being measured along the column;
• a plurality of second conductors disposed in the column, the conductors of the plurality of second conductors having a second width, the second width being measured along the column, and the second width being greater than the first width, wherein the plurality of first conductors and the plurality of second conductors in the column are disposed in a plane;
• and
• a housing comprising a plurality of insulative portions and a plurality of conductive portions, each of the plurality of first conductors of the plurality of columns being disposed, at least in part, within an insulative portion of the plurality of insulative portions, and each of the plurality of second conductors of the plurality of columns being electrically connected to a conductive portion of the plurality of conductive portions,
• wherein adjacent columns of the plurality of columns are separated by a conductive portion of the plurality of conductive portions.
