What is the distance limitation for 10GBASE-T cabling?

The correct answer indicates that the distance limitation for 10GBASE-T cabling is 100 meters. This standard defines the maximum length for a copper twisted pair connection to support 10 Gigabit Ethernet. 10GBASE-T is designed to operate over Category 6 and Category 6A cabling, with the latter being capable of performing reliably up to the full 100-meter length at the 10G speeds.

This specification is crucial for network designers and administrators when planning the layout of a network, especially in large setups where the distance between network devices can influence performance. Understanding this distance limitation ensures that technicians can avoid potential issues pertaining to signal degradation and latency, which can emerge if distances exceed the specified limits.

In this context, the other distance options provided are not suitable for 10GBASE-T. For instance, Category 6 cabling has a reliable distance of up to 55 meters at 10G speeds, but to utilize the full capability of the 10GBASE-T standard without loss of performance, it's important to use Category 6A cabling and stay within the 100-meter range.
