摘要
The minimum number of carrier wavelengths required for full interconnection of a wavelength-routed optical network was determined using the graph colouring of a 'shortest-path graph', derived from the original network description. No two messages with the same carrier wavelength and different source/destination to all possible destinations. The results are applicable to a national wave-division multiplex back-bone network.
