A cable assembly comprises an insulative housing; a plurality of terminals received into the insulative housing; a cable electrically connected to the plurality of terminals. The cable comprises two differential pairs of signal wires. Each differential pair of signal wires comprises two signal wires, a grounding wire and a shielding layer surrounding the two signal wires and a grounding wire. Front end regions of the signal wires and the grounding wires are exposed out of the shielding layer. And, a wire management is assembled to a rear end of the insulative housing and defines a plurality of channels respectively plated with an electroplated layer. The front end regions of the signal wires and the grounding wires are respectively passed through the plurality of channels and electrically connected to the corresponding terminals.
