Nah look closer - its a switch. USB power supply and normal switch LED indicators on the ports.
Idk why they are marketing it as a "splitter" making it sound inferior...that should make for more painful searches next time I need an actual splitter. Which can be handy for like 2x PoE cameras over 1 existing drop...and even 4K cameras will never saturate 100Mbps so its fine.
That is a switch...look closely it requires power and has lights on it. Its just a 3-port wired gigabit network switch.
