  • Publication number: 20240098392
    Abstract: A method performed by an optical network unit (ONU) gateway connecting an access passive optical network (PON) and a home PON for rerouting in-home traffic data back to the home PON. The method includes receiving, by the ONU gateway, an access PON downstream optical signal from an optical line terminal (OLT). The access PON downstream optical signal includes first access traffic intended for the ONU gateway and second access traffic not intended for the ONU gateway. The ONU gateway also receives a home PON upstream optical signal from an ONU of the home PON. The home PON upstream optical signal includes in-home traffic data and upstream access data. The ONU gateway generates a composite downstream signal that includes the first access traffic intended for the ONU gateway and the in-home traffic data. The ONU gateway transmits the composite downstream signal to all ONUs of the home PON.
