Does Cat7 or 7a cable really offer an advantage over Cat6a when supporting 10G
For standard 10GBASE-T Ethernet applications, Cat6a is usually sufficient and provides a good balance of performance, flexibility, and cost. It meets the required performance standards for 10GBASE-T and offers reasonable shielding and interference resistance.Cat7 and Cat7a provide additional shielding and higher frequency performance, which can be advantageous in environments with high EMI or for future-proofing against potential higher-speed applications. However, they are generally more expensive and more challenging to install.In summary: If your primary goal is to support 10GBASE-T Ethernet and you’re looking for a cost-effective solution, Cat6a is likely the best choice. If you anticipate future upgrades to higher-speed networks or need additional shielding due to high EMI, then Cat7 or Cat7a could offer additional benefits.
