Abstract(in English) The nonlinear transmission technology is one of very useful technology for dense wavelength division multiplexing (DWDM) transmission systems. This is because self-phase modulation (SPM) effects can be canceled out by dispersion effects. The transmission characteristics are, however, remarkably degraded by cross-phase modulation (XPM) and so the high launching peak power can not be applied for SNR improvement. in this study, we compare the system using an optical phase conjugator (OPC) at the midway of a dispersion flattened transmission line with the system using nonlinear transmission technology in DWDM transmission. From simulation results, it is shown that the OPC system is more suitable than the system using nonlinear transmission technology because the launching peak power can be added to more than 3dB and dispersion tolerance becomes more than 10 times.
