Abstract:

In the future optical transmission systems, it is likely that Erbium doped fiber optical amplifiers will replace present electrical regenerators. Both experimental studies 1, 2 and computer simulations 3-5 have investigated the feasability of non-regenerated optical long haul systems. A considerable number of parameters are determining the overall performances of the transmission link. In this paper, we report on theoretical studies carried out using numerical simulations in order to investigate the limits of such systems. We have considered both cases of 5 Gbits and 10 Gbits transmission. The theoretical limit value of the amplifier spacing, as imposed by group velocity dispersion GVD, self phase modulation SPM and accumulated amplified spontaneous emission ASE has been evaluated.
