Abstract :
An upgrade of a standard terrestrial fibre network to 40 Gb/s per channel with no signal regeneration is proposed. The technique is based on a quasi-linear transmission scheme with hybrid amplification. The nonlinear management technique is used to obtain the optimal amplification ratio between the gains provided by distributed Raman amplifiers and Erbium doped fibre amplifiers. The impact of the dispersion maps on the transmission performance is investigated. The results show that, by properly choosing the dispersion map, the detrimental nonlinear effects can be significantly suppressed. This hypothesis is confirmed by studying the effect of span average dispersion to the transmission performance.
