Abstract In the discretely amplified transmission systems with erbium-doped fiber amplifiers, the system performance of nonlinearity-compensated optical transmission based on pre-dispersed spectral inversion (PSI) is investigated numerically. We find that PSI offers more significant performance improvement in dispersion-managed (DM) links than that in non-dispersion-managed (noDM) links. On the other hand, the DM link is more sensitive to the span offset from the center of the transmission link than noDM link. The performance difference between DM and noDM links is 1 dB if the span offset equals four spans in 20 × 90 km nonlinear transmission. Furthermore, we show that for the dispersion-managed transmission, in order to obtain the best system performance, the amount of pre-dispersion of the PSI, should be optimized over different dispersion maps.

Effective Use

Эффективное применение цифровых систем передачи невозможно без грамотной организации тактовой син- хронизации. В статье рассмотрена одна из проблем организации тактовой сетевой синхронизации передача сигнала синхронизации с минимальным числом переприемов. Для поиска наиболее эффективного маршрута для передачи сигнала синхронизации предлагается использовать алгоритм Флойда-Уоршалла. Effective use of digital transmission systems is impossible without the competent organization of clock synchronization. The article considers one of the problems of organizing clock network synchronization, namely, the transmission of a synchronization signal with a minimum number of re-receptions. To find the most efficient route for transmitting the synchronization signal, it is proposed to use the Floyd-Warshall algorithm.
