Mi. Hayee et Ae. Willner, PRE-COMPENSATION AND POSTCOMPENSATION OF DISPERSION AND NONLINEARITIES IN 10-GB S WDM SYSTEMS/, IEEE photonics technology letters, 9(9), 1997, pp. 1271-1273
We analyze 10-Gb/s nondispersion-managed and dispersion-managed wavele
ngth-division multiplexed (WDM) systems that use pre-compensation, pos
t-compensation, or dual-compensation of each channel to minimize dispe
rsion and nonlinear effects. We find that dual-compensation gives the
minimal penalty for each channel in dispersion-managed WDM systems, Fu
rthermore, we find that the optimal amount of pre- or post-compensatio
n depends upon the specific dispersion map used in the WDM system.
