TP-LINK's PoE Injector TL-POE150S fully complies with IEEE 802.3af standard. No need to buy a PoE switch, you can use the existing non-PoE switch or non-PoE router to connect PoE devices with the help of TL-POE150S.
The PoE Injector TL-POE150S can work with all IEEE 802.3af PoE compliant PDs (Powered Devices) or PoE Receiver Adapters, such as TP-LINK's TL-POE10R, or other equivalent products, to expand your network to where there are no power lines or outlets, where you wish to fix devices like Wireless Access Points, IP Cameras or IP Phones, etc.
