Multiple reflections from fiber connectors, transmitter and receiver interfaces create multipath interference (MPI) in fiber optic links. MPI converts phase noise to relative intensity noise (RIN) and imposed a severe limit on high-speed PAMn transmission with direct detection. Computed by taking the Fourier transform of the autocorrelation of the time-domain noise term. Multipath interference (MPI) plays a major role in optical communication links, especially in FTTx PON architecture where splitter-based distribution causes reflections from each splitter. Isolators can help mitigate this problem but they are not very suitable for passive networks due to their.
