US Patent 9673570 Stacked cage having different size ports

An electrical connector assembly includes a cage member having walls defining an upper port and a lower port configured to receive pluggable modules therein through a front end of the cage member. The cage member houses a communication connector at a rear of the cage member configured to be electrically connected to the pluggable modules received in the upper and lower ports. The walls are manufactured from a conductive material and providing electrical shielding for the pluggable modules. The plurality of walls include side walls, a top wall between the side walls, a bottom wall between the side walls and a divider wall between the side walls. The divider wall separates the upper port from the lower port. The divider wall is positioned closer to the top wall than the bottom wall such that the lower port is taller than the upper port.
