"The most likely cable construction for Category 8 will be 22-AWG S/FTP cabling"

"For example, a customer might install a Category 8 jack-to-jack link now, but continue to use Category 6A patch cords until the active equipment is upgraded. 

While the ISO standard includes both classes, the TIA Category 8 standard will only recognize a Class I solution.

Category 8 cabling is designed to support emerging IEEE 25GBase-T and 40GBase-T needed as server-to-access-switch interconnect applications.

Category 8 is a 30-meter channel, comprising a 24-meter permanent link and up to 6 meters of patch cable. 

Therefore, when planning data centers with end-of-row or middle-of-row topologies, ensure that your jack-to-jack links are no more than 24 meters in length and that you do not need more than 6 meters of patch cords in total. 

What this means for patching is you could have two, 3-meter patch cords, a 1-meter and a 5-meter patch cord, or any combination that adds up to 6 meters or less." 

The TIA-568.2-D standard will, in all likelihood, incorporate the following.

  • The content of ANSI/TIA-568-C.2-1, Category 8 specifications
  • The content of ANSI/TIA-568-C.2-2, which describes alternative test procedures for Category 6A patch cords
  • Refinements to test procedures for cabling and components, as well as extrapolation to 2,000 MHz from the previous maximum frequency of 500 MHz
  • Resistance parameters that are needed for support of remote powering applications
