Cat6A Ethernet cable, often called Category 6A, is a cable standard designed for 10 Gigabit Ethernet. It offers up to 600MHz performance and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T / 1000BASE-TX (Gigabit Ethernet), and 10GBASE-T (10 Gigabit Ethernet) networks. It's backwards compatible with earlier standards like Cat6, Cat5e, and Cat5.
