Which Ethernet standard provides 10 Gigabit Ethernet at 10 Gbps over copper cabling with a maximum distance of 100 meters?

• A. 10GBASE-T
• B. 1000BASE-T
• C. 100BASE-TX
• D. 1000BASE-SX

Answer: (A)

The main idea is delivering 10 gigabits per second over copper Ethernet within a 100-meter reach. That capability is provided by the 10GBASE-T standard. It uses all four twisted pairs of copper cabling and, with appropriate category copper (Cat6a or better), can run at 10 Gbps up to 100 meters. This makes it the copper-based option that meets both the speed and distance requirements. The other options do not fit because they either operate at lower speeds or use fiber instead of copper. A 1 Gbps copper standard runs up to 100 meters but isn’t 10 Gbps. A 100 Mbps copper standard is even slower. And a fiber-based standard (even if it supports long distances) isn’t copper, so it doesn’t match the “over copper cabling” condition.
