Passive optical network

A passive optical network has an input port (500) and a plurality of output ports (520). It responds to input optical signals in a first wavelength region ( lambda mon) by routing them to respective output ports, depending on their wavelengths (demultiplexing 610). It responds to input optical signa...

Summary:A passive optical network has an input port (500) and a plurality of output ports (520). It responds to input optical signals in a first wavelength region ( lambda mon) by routing them to respective output ports, depending on their wavelengths (demultiplexing 610). It responds to input optical signals in a second wavelength region lambda s by routing a portion to each of the output ports (star coupling 510).
