The PoE strip is used to transmit power to active devices using a UTP/FTP cable.
Power over Ethernet, or PoE for short, is a technology based on several standards for the transmission of electricity via twisted-pair cable to Ethernet peripheral devices.
Many types of PoE injectors are available on the market. The choice depends on how many devices we want to connect, whether it is possible to mount them in a rack etc.
