Power Injectors: Small Devices, Big Network Impact
Power Injectors are compact networking devices designed to supply electrical power to compatible equipment over an Ethernet cable. Commonly used in Power over Ethernet (PoE) environments, they eliminate the need for separate power adapters, helping create cleaner and more efficient installations. Devices such as wireless access points, IP cameras, and VoIP phones often rely on power injectors for stable operation.
How Power Injectors Work
A Power Injector functions by inserting electrical power into a standard Ethernet cable without interfering with data transmission. One port connects to a network switch or router for data input, while another port delivers both power and data to the powered device. This dual functionality allows network administrators to extend device placement beyond traditional power outlets.
