Abstract:
1. An optical deaggregator receiving an input line carrying a plurality (n) of optical channels modulated at different wavelengths, said deaggregator dividing the plurality of optical channels into at least a first group of optical channels having a first population of different modulating wavelengths and a second group of optical channels having a second population of different modulating wavelengths, wherein the first and second population differ in value from each other, wherein said plurality of (n) optical channels include at least eight different modulating wavelengths, and said first population comprises an integer value of more than 0.25n number of modulating wavelengths and said second population includes a non-zero integer value of less than 0.25n number of modulating wavelengths, wherein said first population of different modulating wavelength and said second population of different modulating wavelength are passed through at least one optical selector.
