Abstract:
1. An Optical Network Unit (ONU) comprising: at least two logic-independent virtual ONUs each adapted to process a packet based on a respective pre-configured protocol, wherein a first virtual ONU of the at least two logic-independent virtual ONUs is configured to perform PPP over ATM (PPPoA)-based forwarding and ATM Passive Optical Network (PON) adaptation; wherein a second virtual ONU of the at least two logic-independent virtual ONUs is configured to perform PPP over Ethernet (PPPoE)-based forwarding and Ethernet PON adaptation; a user interface unit connected with one or more Customer Premises Equipments (CPEs) via a Digital Subscriber Line (DSL), an Ethernet Line or a Power Line Communication Line, for processing Physical Layer and Data Link Layer of the DSL, the Ethernet Line or the Power Line Communication Line, and for sending a packet from the one or more CPEs to the corresponding virtual ONU; and an Optical Distribution Node interface unit connected with one or more Optical Line Terminals (OLTs) via an Optical Distribution Node (ODN), for sending a packet processed by the virtual ONU to the OLT corresponding to the virtual ONU.
