发明名称	Method and system for propagating upstream cable modem signals and RF return video control signals over the same optical network
摘要	A method and system can propagate upstream cable modem signals and radio-frequency (RF) return video control signals over the same passive optical network (PON). The method and system can include various combinations of hardware and software to support this operation. Three exemplary embodiments of optical network terminals (ONT) of a DPON system improve performance of the system by ensuring that, in the event the upstream transmitters of two ONTs are turned on simultaneously, they will not interfere with each other. The system is designed such that in a situation of competing transmissions, the one which is received and processed by the head end out of two competing transmissions originating from a set top box and a cable modem, will be the one originating from the cable modem, which may use the DOCSIS cable modem protocol.
