GoKawiilEthernet cable category alone doesn't determine your actual network speed
Actual network throughput is capped by the weakest link in the chain, whether that's your internet plan, router or switch port, network adapter, cable quality, or cable run length. Cat5e can support 2.5Gbps and 5Gbps per TIA guidance, Cat6 can hit 10Gbps only up to 37-55 meters, and Cat6A is needed for 10Gbps at the full 100-meter distance. Cat8 supports 25-40Gbps but only over 30 meters and was built for data centers, while Cat7 is recognized by ISO but not by TIA in North America.
GoKawiil's interpretation of the reporting above, not reported fact.
Buyers often assume a higher cable category number automatically means faster real-world speeds, which the cabling standards themselves contradict once distance and other network components are factored in. This suggests consumers could be overspending on premium cables like Cat8 without any practical benefit for home networking, since bottlenecks elsewhere in the chain often limit performance anyway.
- Overall network speed is limited by the slowest component in the chain, not just the cable.
- Cat5e and Cat6 can exceed their commonly assumed speeds depending on run length, per TIA guidance.
- Cat7 and Cat8 involve inconsistent standards recognition and are largely unnecessary for typical home use.
Cat6A Ethernet Cable (Cable Matters) — If you want reliable 10Gbps speeds across a full 100-meter run without worrying about interference, Cat6A is the sensible middle ground mentioned in the article. It's shielded, future-proof, and won't cost you the data-center-grade premium of Cat8 that most homes simply don't need.
