Abstract

In this paper influence of high-precision optical inline dispersion compensation and ideal electric domain dispersion compensation in 100Gbit/s coherent detection polarization division multiplexing quadrature phase shift keying (PDMQPSK) system are studied by numerical simulation. The results show that the system performance of the system without optical inline dispersion compensation is significantly better than the system with high-precision inline dispersion compensation, and the system with ideal electric domain dispersion compensation is more suitable for long-distance transmission. We also try to search the optimal ratio of inline dispersion compensation in high-precision optical inline dispersion compensation system. We discover that there is not the ratio that can make the performance of the highprecision optical inline dispersion compensation system significantly better than the other ratio in a certain range of inline dispersion compensation ratio. Furthermore, the performance of the high-precision inline dispersion compensation system is obviously worse than the ideal electric domain dispersion compensation system when the ratio is optimal, and the performance is a little better than the performance when the ratio is 100%.
