Abstract

In the design of higher capacity and longer distance WDM transmission systems, it is very critical to make the all signal channels having almost equal performances in terms of signal power, optical signal-to-noise ratio (OSNR), Q-factor, accumulative/residual dispersion and so on. Both signal-to-signal stimulated Raman scattering and wavelength dependence of fiber loss degrade the signal power and the OSNR especially in shorter wavelength band. In order to compensate these degradations, it is useful to independently control the spectra of noise figure and Raman gain.
