Commscope Cat 8 Cabling
• This contribution is being made to show the technical feasibility of a category 8 cabling system
• Broad market potential and compatibility are supported by the RJ-45 connector
• These complete cabling channels consist of the following– One long and one short channel– Horizontal cable– Two connectors– A patch cord at each end of each channel

Commscope Cat 8 Cabling
• Differences from the previous contribution– Complete channel, not only permanent link
– All components from the same vendor• Demonstrates existence of two connecting
hardware manufacturers

Conclusions
• Verification that the channel models are correct, based on another manufacturer’s connecting hardware
• So far two cabling companies have demonstrated prototype category 8 connectors and one has demonstrated category 8 cable
• These designs are expected to improve in the future leading to fully meeting all requirements in production
• Technical feasibility, broad market potential, and compatibility are supported by this data
