Patent ID: 10686621

Abstract:
A system for digital aggregation of upstream traffic includes digital optical node units (DONUs), each assigned a corresponding timeslot and a corresponding frequency band for transmission of digital data. Each DONU converts a radio frequency burst into the corresponding intermediate frequency (IF) band and transmits the corresponding IF data onto one of the optical fiber spans at the corresponding timeslot to an optical passive splitter. The optical passive splitter receives the digital data from the DONUs without collision, combines the IF data from each of the DONUs into a combined digital data, and sends the combined digital data to the digital RFoG transceiver over a single span. The digital RFoG transceiver recovers IF data for each of the DONUs from the combined digital data, converts the IF data to RF data, combines plurality of RF data, converts the digital combined RF data to analog RF data and outputs the analog data to the network.
