In an optical access network architecture based on Dense Wavelength Division Multiplexing (DWDM) a central laser source in the central station provides a large number of wavelength channels. Optical interleavers are then used to partition and finally demultiplex the set of available wavelengths to provide one bi-directional wavelength channel per access node, the central station being the only laser source in this network. The laser source provides a large number of very tightly spaced wavelength channels. Each access node retrieves the laser source from the signal received from the central station to be used in modulating its upstream signals. This access network architecture provides one wavelength channel for each access node, and hence enables protocol and data rate transparency on each channel.
