1. A system for processing communication signals in an Orthogonal Frequency Division Multiple Access (OFDMA)-Passive Optical Network (PON) comprising:

  • an optical line terminal (OLT) configured to transmit first signals on a wavelength generated by an optical source in the OLT;

    a plurality of optical network units (ONUs), wherein each optical network unit (ONU) is configured to receive the first signals on the wavelength, perform carrier suppression on an optical carrier on the wavelength received from the OLT and modulate the suppressed optical carrier to generate upstream optical OFDM data signals for transmission to the OLT on the wavelength.
