摘要： A hybrid passive optical network (PON) includes a central office (CO) for multiplexing at least one downstream optical signal for broadcasting and a plurality of downstream optical signals for communication. The PON further includes a remote node (RN) connected to the CO using at least one feeder fiber (FF), and a plurality of optical network units (ONUs), each connected to the RN using at least one distribution fiber (DF). The RN demultiplexes the multiplexed downstream optical signal received from the CO into the downstream optical signal for broadcasting and the downstream optical signals for communication, and multi-splits the downstream optical signal for broadcasting. The RN transmits each split broadcasting downstream optical signal and its corresponding downstream optical signal for communication to each ONU.

摘要： A WDM hubbed ring network includes a single central office connected to a plurality of remote nodes by one optical transmission line. The central office generates at each wavelength corresponding to each channel in a first channel group a high-priority optical signal and a low-priority optical signal. These signals are then WDM-multiplexed and transmitted to each of the remote nodes in different directions along the ring via the optical transmission line. The central office receives a high-priority optical signal and a low-priority optical signal with a wavelength corresponding to each channel in a second channel group from the remote nodes via the optical transmission line in different directions.
