The PoE extender can be used to repeat the network for non-POE devices such as WiFi routers. A POE injector and a POE splitter are required. The standard PoE injector will verify the edge device before it releases the power. If the PoE splitter does not exist in the system, the POE injector will not send the power, and the POE extender can’t take the power inline. The PoE extender doesn’t need an external power source. This is the Long Distance PoE extender which can supply 300 meters PoE Network instead of 100 meters. The long-distance chipset is built into the extenders. It is just the Ethernet cable between two ends, you can bury the cable directly without involving the PoE extenders.
