Power over Ethernet (**PoE**) provides a way for your network devices to be powered by their data cables rather than by separate power cords. In many applications, particularly in the installation of touch panels, keyboards, sensors, wireless access points, or IP telephones, PoE can significantly reduce installation costs.

Power Over Ethernet (PoE) integrates power and data onto one single cabling infrastructure, eliminating the need to have AC power adapters available at all locations. The **IEEE 802.3af** and **IEEE 802.3at** standards define how products should provide and receive power over the data infrastructure.

Using category 5/5e cable or better, PoE will provide power to PoE-compatible devices, such as touch panels, IP telephones, wireless LAN access points, and IP cameras, for a **distance up to 100 Meters**. Products that are powered by PoE are generically called powered Devices (PD). PoE is already widely adopted in the market, saving up to 50% of overall installation costs by eliminating the need to install separate electrical wiring and power outlets in new or hard-to-reach places.
