Optimisation of 80×10Gbit/s Ultra long-haul DWDM systems

چکیده
This paper outlines an approach to modelling ultra long-haul DWDM links taking into account spectral variations of gain and noise in EDFAs. A black-box model is used to describe EDFA gain and noise figure tilt and full nonlinear simulations are carried out using the split-step Fourier method. The effect of pre-emphasis and power optimisation is investigated for a typical ultra long-haul link of approximately 3000km.
