Plug assembly and receptacle assembly with two rows

A receptacle assembly, comprising:

• a cage defining, at least in part, a port, the cage including a front face, a top wall, a plurality of side walls, and a rear wall, the cage having a length between the front face and the rear wall, the cage configured to be mounted to a circuit board, and the port configured to have an insertion direction parallel to the top wall and the circuit board;
• and
• a connector configured to be mounted to the circuit board and to be positioned in the cage between the top wall and the circuit board, the connector including a card slot aligned with the port and having the same insertion direction, the card slot recessed in the port rearward of the front face, wherein:
• the connector includes a first pair of opposing contacts configured to mate with opposing pads on a mating blade in a first connection region when the mating blade is inserted into the card slot in the insertion direction, the connector includes a second pair of opposing contacts configured to mate with opposing pads on the mating blade in a second connection region when the mating blade is inserted into the card slot in the insertion direction, the second connection region positioned rearward of the first connection region and the first connection region positioned rearward of the front face of the cage by a distance of at least one third of the length of the cage, the first pair of opposing contacts are provided by a first set of terminals that are supported in a cantilevered manner, each first terminal among the first set of terminals has an embedded portion that is embedded in a frame and has a cantilevered portion, the cantilevered portion of each first terminal being that portion not embedded in contact with the frame and extending to a contact point of that first terminal, the cantilevered portion of the first set of terminals starts forward of the second connection region while the embedded portion of the first set of terminals is adjacent the second connection region and frame material is positioned between each first terminal of the first set of terminals and forward the second pair of opposing contacts, the receptacle assembly is configured to provide a 200 Gbps 8 X connection that is compatible with a QSFP style plug connector, and the first set of terminals are configured to electrically connect opposing pads on the mating blade to the circuit board when the mating blade is inserted into the card slot in the insertion direction.
