Cat6a is a type of Ethernet cable designed for high-speed data transmission. It supports frequencies up to 500 MHz and can transmit data at speeds of 10 Gbps over distances of up to 100 meters. This makes it suitable for demanding applications like video streaming and online gaming. The "a" in Cat6a stands for "augmented," indicating improvements over the earlier Cat6 standard. Cat6a cables are thicker and have better shielding, which helps reduce interference and crosstalk. This makes them ideal for use in data centers and other environments where reliable, high-speed connections are essential.
