Propagation analysis of an 80-Gb/s wavelength-converted signal utilizing cross-phase modulation

For robust operation of high speed networks, wavelength conversion, as well as new signal processing and coding techniques are important. In this thesis, we model the propagation of an 80-Gb/s wavelength-converted signal gener- ated by utilizing cross-phase modulation (XPM) in a highly nonlinear fiber. We then compare the transmission performance of the wavelength-converted signal to that of the standard signal. After propagation over 1280 km or less, wavelength conversion adds no signal degradation in terms of BER. We conclude that wavelength conversion leads to no significant deterioration in a noise-limited propagation system
