Please take the Windows Mac war to another topic. I read
here that Category 8 is intended only for the data center. It is called 40GBase-T or 40G for short, meaning 40 gigabits per second. The article also has a picture of the cables. Category 8.1 has 4 untwisted pairs plus an overall foil sheath. Category 8.2 has a foil sheath around each pair plus an overall foil plus braided sheath.
