Which IEEE standard corresponds to 1 Gbps Ethernet?

The standard that corresponds to 1 Gbps Ethernet is indeed found within the IEEE 802.3 family. Specifically, 802.3ab defines the specifications for 1000BASE-T, which allows for 1 Gbps data rates over twisted-pair cabling, commonly using Cat 5e or Cat 6 cables. This standard was established to facilitate gigabit Ethernet connections in local area networks (LANs).

Understanding the context of other standards within the IEEE 802.3 series provides clarity on their respective data rates:

• 802.3i pertains to 10BASE-T, which supports speeds of 10 Mbps.

• 802.3u describes 100BASE-TX, enabling data transmission rates of 100 Mbps.

• 802.3an, while related to Ethernet standards, actually defines 10GBASE-T for 10 Gbps speeds.

This overview helps establish 802.3ab as the correct reference for 1 Gbps Ethernet, highlighting its role in networking and the evolution of Ethernet technologies.
