Why is there an internal foil on the new design of Cat6A cable, 2D4P6AIPV3R-BU?

The internal foil is designed to assist with immunity to external noise as defined as ‘Alien cross-talk’. “Alien cross-talk” has a predominant effect on the transmission at 10 Gbps speed. This foil design helps to provide full EMI protection (coupling attenuation (AC) > 55dB, Type II coupling attenuation. ANEXT and AFEXT are proven by design)
