Power over Ethernet (PoE) is a technology that allows power and data to be transmitted over a single Ethernet cable. PoE is a convenient way to provide power to network-connected devices such as IP phones, wireless access points, security cameras, and other devices that are connected via Ethernet.
PoE works by sending electrical power through the data lines of an Ethernet cable along with the data signals. Power is transmitted from a PoE-enabled network switch or PoE injector to the device that needs to be powered. This eliminates the need for additional power cables and simplifies the installation of devices that require power.
PoE cables are available in two different varieties – Category 5 (CAT5) and Category 6 (CAT6). CAT5 cables are capable of delivering up to 15.4W of power while CAT6 cables can deliver up to 25.5W. The wattage that can be delivered depends on the type of PoE technology that is being used.
PoE cables make it easy to power devices in hard-to-reach locations, such as in ceilings or walls, without having to run additional power cables. This makes PoE a great solution for installations where power outlets are not available or are difficult to access.
PoE is a cost-effective and efficient way to provide power to devices that require a connection to a network. It simplifies the installation of network-connected devices and eliminates the need for additional power cables.
