Abstract:
A method for coupling a head-end to end-users, comprising:providing a concentrator; connecting the head-end to the concentrator; connecting a plurality of mini-fiber-nodes (mFNs) to the concentrator; connecting the end-users to the mFNs; receiving a first downstream communication signal from the head-end; demultiplexing the first downstream communication signal; transmitting demultiplexed signals to the mFNs based on destination information of each of the demultiplexed signals; receiving a second downstream communication signal together with the first downstream signal from the head-end, the second downstream communication signal being one of a digital signal or analog signal; demultiplexing the first and the second downstream communication signals into one or more demultiplexed signals; modulating a portion of the demultiplexed signals destined to one or more fiber nodes onto radio frequency carriers if the second downstream communication signal is digital; and transmitting one or more modulated signals to the fiber nodes.
