CAT6a cables are designed to support up to 10 Gbps speeds and up to a 100-meter channel length, which makes them suitable for a 10GBase-T network. CAT5e, although capable of 1 Gbps speeds, does not support 10 Gbps necessary for 10GBase-T. CAT7 cables are indeed capable of up to 10 Gbps speeds, but they are optimized for frequencies up to 600 MHz, which is more than required for 10GBase-T, making CAT6a a more cost-effective and sufficiently capable option. CAT3 is primarily used for telephone installations and supports much lower speeds, making it unsuitable for 10GBase-T requirements.
