What is the maximum frequency rating for Cat 6a cables?

The maximum frequency rating for Category 6a (Cat 6a) cables is indeed 500 MHz. This specification allows Cat 6a cables to support 10 Gigabit Ethernet (10GBASE-T) over distances of up to 100 meters. The increased frequency rating compared to earlier categories is essential for accommodating the higher data transfer rates that are needed in modern networking environments. It enables more efficient transmission of signals and reduces crosstalk and interference, which are critical for maintaining high performance and signal integrity in networks that require robust data transmission capabilities.
