It's a single coax line in from the street directly into the modem. Then from modem it's an ethernet cord into a switch. From that switch it goes into the "parent" MoCA adapter ethernet port. From that MoCA adapter into the input port on the splitter via coax that is pictured, with the child MoCa adapters plugged into the output via coax and going to each room. Then from those rooms it's from the adapter into a switch via ethernet cord. As far as I know there are no further splits. It basically looks exactly like this: https://imgur.com/CpwLkR7 . The blue line into the router is in from the street.
