Power over Ethernet (PoE)

Power over Ethernet (PoE) is a technology that allows both power and data to travel over an Ethernet cable. It ensures that the Ethernet cable is no longer just a data-carrying cable; it is now also a power-carrying cable. It is a way of using an RJ45 cable to transmit both power and data signals. In this way, it is now possible to use the same cable to connect the device (now called a powered device, PD) to the power source (called the power sourcing equipment, PSE) and also to connect the PD to the network, all at the same time. When you install PoE devices, you have the option to not use traditional electrical outlets at all because the PoE standard allows devices to be powered anywhere you can get an active Ethernet cable.

Network switches are an essential part of any network. They are the central connecting point for many devices in a system. Some switches go further by providing power. Power over Ethernet (PoE) switches serve several functions within a network. They allow us to push power, they can still switch frames, and they also expand port counts.

Commonly found between a switch without Power over Ethernet (PoE) support and a device that requires PoE (like an IP camera), PoE injectors are essential energy-boosting devices that give a network cable the power it needs to ensure a PoE device can work properly with no glitches. When the costs of a switch and the number of ports needed make them impractical for use at the edge of the network, a Power over Ethernet solution can be equally effective in the tasks just described.
