Efficient Design of High-Capacity Dense Wavelength-Division Multiplex Systems
Taking into account local and accumulated group velocity dispersion, impairments due to fibre nonlinearities are described as a function of the average optical input power per channel. In combination with the degradation of the optical signal-to-noise ratio caused by optical amplifier noise the maximum transmission distance versus optical input power can be determined.
The validity of the models is verified by means of numerical simulations and system experiments. The dependence on data rate, modulation format, fibre type and dispersion compensation scheme is determined. Practical examples illustrate the usefulness of our design approach.
