The PoE Gigabit Injector is used to transfer power to active devices using a UTP/FTP cable.
PoE is a technology based on several standards for the transmission of electricity via twisted-pair cable to Ethernet peripheral devices.
There are many types of PoE injectors on the market. It all depends on how many devices we want to connect, whether there is a possibility of mounting in a rack etc.
