Abstract
Various methods and apparatuses are described in which data transmission in two or more discrete wavelength bands are routed in the same transmission direction between a central office and a remote node in a wavelength-division-multiplexed passive-optical-network (WDM PON). The two or more discrete wavelength bands are separated by at least ten nanometers in wavelength spectrum. Further, each wavelength band contains two or more optical wavelength channels within that wavelength band.
