Here is a pseudo-code illustration to clearfy the structure:

}

class EthernetCommunicator implements Communicator { /* … */ }
class USBCommunicator implements Communicator { /* … */ }

abstract class CommunicationManager {
 abstract Communicator createCommunicator();
 // common methods like retry logic, logging
}

class EthernetManager extends CommunicationManager {
 Communicator createCommunicator() { return new EthernetCommunicator(); }
}

class USBManager extends CommunicationManager {
 Communicator createCommunicator() { return new USBCommunicator(); }
}

// Client
string protocol = getConfiguration("comm_protocol");
CommunicationManager manager;
if (protocol == "ethernet") manager = new EthernetManager();
else if (protocol == "usb") manager = new USBManager();
// …
