Wired Ethernet has been the backbone of networking since its inception, providing a reliable and stable medium for data transmission across devices and networks. Over the years, Ethernet technology has seen significant advancements, evolving from its original 10 Mbps to the current capabilities exceeding 400 Gbps. This evolution has been driven by the continuous need for higher bandwidth, lower latency, and more efficient network infrastructures.

Ethernet's importance lies not only in its speed and reliability but also in its ability to adapt to the growing demands of modern networks. One of the major milestone in Ethernet's development has been the transition from copper to fibre-optic cabling, enabling much greater distances and speeds while reducing susceptibility to electromagnetic interference. The introduction of Power over Ethernet (PoE) has been another major technological enabler, greatly simplifying the implementation of wireless access points, security cameras, and point-to-point transmitters. The evolution and adoption of advanced modulation techniques and higher-order encoding schemes has also further pushed the boundaries of data rates and channel efficiency.

For those with a background in wireless technologies, the principles of Ethernet will resonate, as both share the goal of efficient, high-quality data transmission, albeit through different mediums. Dive deeper into the specifics of Wired Ethernet, including the latest standards and techniques, by exploring the sections below.

Power over Ethernet (PoE) is a technology that allows network cables to carry electrical power. This system eliminates the need for a separate power supply, simplifying the process of installing networked devices such as IP cameras or wireless access points. PoE works by running power over the same cables used to transmit internet data. This is accomplished through the use of a PoE switch or injector, which adds power to the Ethernet cable at the source, and a PoE-capable device at the ...
