Abstract :
We present a generalized momentum method to describe evolution of the root-mean-square (rms) (averaged over time) optical pulse characteristics in dispersion-managed fiber lines. A closed system of the ordinary differential equations is derived for the rms pulse power, width, and chirp. The developed method can be useful for massive numerical simulations required to optimize wavelength-division-multiplexing dispersion-managed transmission using chirped return-to-zero format.
