摘要
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 (PDM-QPSK) 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 high-precision 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%.
