1. PoE switch

A Power over Ethernet (PoE) switch is a networking device that combines the functionality of a standard Ethernet switch with the ability to provide power to connected devices over the same Ethernet cable used for data transmission. This technology eliminates the need for separate power cables, simplifying installation and reducing costs, especially in areas where power outlets are limited. PoE switches can supply power to devices like IP cameras, VoIP phones, and wireless access points, making them ideal for powering network devices in locations where electrical outlets may not be readily available. By integrating data and power delivery into a single cable, PoE switches offer a convenient and efficient solution for network connectivity and device power supply.
