Abstract:
1. An optical network remote node comprising: first and second node inputs, each receiving a multiplexed optical signal; node outputs, each outputting a separate replicated or demultiplexed optical signal; first and second optical power splitters, each having a splitter input connected to one of the node inputs and splitter outputs connected to corresponding node outputs; an arrayed waveguide grating having first and second grating inputs connected to the first and second node inputs, respectively, and grating outputs connected to the corresponding node outputs, the arrayed waveguide grating having a demultiplexing ratio equal to the sum of the splitting ratios of the first and second optical power splitters; wherein if the multiplexed optical signal received at one of the node inputs is time division multiplexed, the corresponding connected optical power splitter replicates the received optical signal and outputs the replicated signals at the node outputs; and wherein if the optical signal received at one of the node inputs is wavelength division multiplexed, the arrayed waveguide grating demultiplexes the received optical signals and outputs the demultiplexed signals at the node outputs.
