Abstract :
We report on the impact of the laser linewidth on the performance of OFDM-FSK systems when single-cavity Fabry-Perot filters are used as demultiplexers. The coherence of optical source is considered both in the analysis and for the bit error rate calculations. The results confirm that in order to arrange the channels efficiently the laser linewidth must be considered.<>
