An electrical connector assembly includes a shielding cage member having an upper port and a lower port configured to receive pluggable modules therein with side walls along the sides of the upper and lower ports. A separator member extends between the side walls between the upper and lower ports. The separator member has an upper plate and a lower plate with a channel therebetween. The upper and lower plates have interior surface facing the channel and exterior surfaces facing the upper and lower ports, respectively. RF absorbers are positioned along the exterior surfaces and are exposed along the upper and lower ports. The RF absorbers reduce an amount of EMI propagation through the cage member. A divider wall is positioned in the channel and extends between the interior surfaces of the upper and lower plates.
