Abstract: Various example embodiments supporting optical communications in an optical communication system may be configured to support joint stimulated Brillouin scattering (SBS) suppression and polarization tracking for a set of orthogonal polarization optical channels in an intensity modulated/direct detection (IM/DD) passive optical network (PON). Various example embodiments may be configured to support joint SBS suppression and polarization tracking for a set of orthogonal polarization optical channels based on a set of frequency tones (e.g., using a single frequency tone per optical channel in the set of orthogonal polarization optical channels, respectively) such that SBS suppression is supported for transmissions from the transmitter (e.g., based on application of the frequency tones to the optical channels) and polarization tracking is supported at the receiver (e.g., based on use of one or more of the frequency tones of the optical channels in the set of orthogonal polarization optical channels for polarization tracking).
