Abstract
The present disclosure discloses a method and an apparatus for hybrid multiplexing/de-multiplexing in a passive optical network, the method comprising steps of: dividing N first intermediate frequency sub-bands averagely into M clusters, wherein each of the clusters contains K first intermediate frequency sub bands and N=M*K, and wherein each of the K first intermediate frequency sub-bands carries a baseband digital electrical signal; selecting, by a software defined first intermediate frequency multiplexer, the baseband digital electrical signals of K first intermediate frequency sub-bands from the N first intermediate frequency sub-bands for software defined frequency division multiplexing and forming a cluster; and frequency division multiplexing, by an analog hardware cluster multiplexer, analog electrical signals of the M clusters on a second intermediate frequency sub-band.
