10 gigabit Ethernet is a telecommunication technology that offers data speeds up to 10 billion bits per second. 10 gigabit Ethernet (10-Gigabit Ethernet) is also known as 10GE, 10GbE or 10 GigE.

The 10 GbE standard is fully interoperable with existing Ethernet protocols. It differs from traditional Ethernet in that it is a full-duplex protocol, meaning it does not need Carrier Sense Multiple Access/Collision Detection (CSMA/CD) protocols. In every other way, 10 GbE is the same as the original Ethernet protocol. This is important for network managers because as the demand for speed increases, 10 Gb Ethernet can easily be deployed within existing networks, providing a cost-effective technology that can support high-speed, low-latency requirements.
