Abstract

An electrical receptacle connector is mounted within a metallic cage for mating with a SFP module received within the cage. The contacts of the cable receptacle connector are arranged with two groups, of which one are connected to the printed circuit board on which the cage is mounted, and the other are connected to the wires which are further connected to a board-mount receptacle connector mounted on another printed circuit board on which the CPU (Central Processing Unit) socket is mounted. Each board-mount receptacle connector corresponds to more than one cable receptacle connector.
