The image shows an Active Power over Ethernet (PoE) Splitter, a networking accessory used to supply power and data to non-PoE devices.How It WorksA PoE Splitter acts as an intermediary component in a network layout:Input: A standard Ethernet cable carrying both data and high-voltage power (typically 48V) from a PoE switch or injector plugs into the female RJ45 port on the main housing.Internal Conversion: The internal circuit steps down the voltage to a lower, stable output—commonly 12V DC.Output: It separates the combined stream back out into two distinct tails at the other end:A male RJ45 Ethernet connector to deliver data.A DC barrel jack to provide power
