## AI overview

This tutorial explains how NBASE-T provides 2.5 Gbps and 5 Gbps Ethernet speeds between traditional Gigabit and 10 Gigabit Ethernet over existing copper cabling. It covers auto-negotiation, RJ-45 compatibility, and use cases such as Wi-Fi access points and security cameras.

## Source excerpt

NBASE-T bridges the gap between 1 Gigabit and 10 Gigabit Ethernet by supporting 2.5 Gbps and 5 Gbps over existing copper cabling. Learn how it works, where it makes sense, and what network engineers should look for when deploying and troubleshooting multi-gigabit links. The post What Is NBASE-T?
