The PoE splitter and combiner kit is an economical and practical solution for powering and transmitting data to 2 devices with 100 Mbps line speed over a single Ethernet cable over a distance of up to 100m. Wires 1.2 (+) and 3.6 (-) are always used for data transmission and power supply. The combiner at the input combines 2 cables (it always uses only 4 cores from each cable) connected, for example, to a switch with 802.3af/at PoE support, and the subsequent splitter at the end divides it again and it is possible to connect, for example, 2 cameras from them. This method of use is used when there is an insufficient number of installed cables and a small speed requirement, for example for connecting IP cameras, IoT, Wi-Fi AP, etc.
