“…However, e.g., for systems with 40 Gbit/s channel rate and 100 GHz channel spacing a transmission fiber with a reduced dispersion of about 6…10 ps/(km nm) had been found to yield an improved performance compared to standard single mode fiber [21]. It is therefore of interest to look for the optimum transmission fiber in spectrally more efficient systems with a spectral efficiency of 0.8 bits/s/Hz.…”

In order to efficiently use the available optical bandwidth efforts are under way to achieve spectral efficiencies of at least 0.8 bits/s/Hz. For such spectrally efficient systems (considering co-polarized WDM-channels) the importance of filtering for different modulation formats, different channel bitrates from 10 -160 Gbit/s and different dispersion map designs will be discussed. It turns out that the optimisation strategy for spectrally efficient WDM systems shows considerable differences to single channel systems. The specific modulation format and the chosen channel bitrate turn out to be of minor importance, thus enabling simple analytic expressions for the achievable system performance.
