Connector and connector system having edge-coupled terminals

A connector, comprising:

• a housing having a mating face;
• a first wafer and a second wafer supported by the housing and positioned adjacent each other, the first and second wafers each having a first edge and a second edge and a first side and a second side, wherein the second side of the first wafer is adjacent the first side of the second wafer;
• a pair of signal terminals supported by each of the wafers, each of the terminals in the signal pairs having a contact extending from the first edge, a tail extending from the second edge and a body extending between the contact and the tail, the pair of signal terminals being arranged for edge-coupling;
• a ground terminal supported by the first wafer and positioned adjacent the pair of signal terminals supported by the first wafer, the ground terminal having a ground contact, a ground tail and a ground body extending between the ground contact and the ground tail, the ground terminal and the pair of signal terminals forming a single column;
• and
• a shield supported by the first wafer on the first side, the shield having a groove formed by a wall with two arms formed in the shield and extending from the wall, the wall of the groove aligned with the bodies of the pair of signal terminals supported by the first wafer so that the two arms are positioned on opposite sides of the pair of signal terminals supported by the first wafer.
