Q-map is a very practical method for the design of high-speed optical communication lines, not only soliton-based systems but also wavelength division multiplexing (WDM) systems. We applied Q-maps to the optimization of periodically dispersion compensated 40 Gbit/s soliton systems and 40 Gbit/s based WDM systems. In soliton-based systems using dispersion-shifted fibers (DSF), optimal signal power is about +5 dBm and the optimal dispersion compensation is about ±30 ps/nm. In WDM systems using non-zero dispersion-shifted fibers (NZDSF) or single-mode fibers (SMF), optimal signal power is about -5 dBm and amplifier noise becomes critical. The optimal channel spacing and dependence of channel numbers are discussed. Tera-bit class systems require very accurate dispersion compensation and low-noise amplifiers.
