Abstract :
This letter presents a theoretical performance assessment assuming that single- and double-cavity Fabry-Perot filters are used as demultiplexers in two-channel dispersion supported transmission systems operated at 10 Gb/s. A suitable simulation methodology has been used that combines signal simulation with noise analysis in optically amplified multichannel direct detection systems. The results obtained show an improved system performance if a double-cavity Fabry-Perot filter is used as a demultiplexer, resulting in a WDM transmission with a crosstalk power penalty within 1 dB in the region of low dispersion penalty of the DST method, for a channel spacing of 1 nm. The robustness against dependencies on data patterns is verified.<>
