Description

This paper discusses the impact of double cavity Fabry-Perot demultiplexers on the performance of wavelength division multiplexing (WDM) systems with dispersion supported transmission (DST) of three 10 Gbit/s channels separated 1 nm. For performance assessment, a suitable simulation methodology has been used which combines signal simulation with noise analysis in optically amplified multichannel direct detection systems. Simulation results show an improved system performance if a double cavity Fabry-Perot filter is used as demultiplexer, resulting in WDM transmission with a crosstalk penalty less than 1 dB in the region of small linear increase of dispersion penalty of the DST method. The robustness of the multichannel DST method against data pattern dependencies is investigated. http://dx.doi.org/10.1002/ett.4460080212
