摘要
研究了NRZ-DPSK和NRZ-DQPSKG.655光纤40Gb/sDWDM通信系统中预补偿和逐段补偿两种色散补偿方案。通过仿真对比了这两种方案的色散性能和非线性性能,得出预补偿方案优于逐段补偿方案。在未来50GHz通道间隔40Gb/sDWDM系统中,采用预补偿能获得更好的传输性能。
Tow schemes of dispersion compensation, pre-compensation and section-by-section compensation, are studied in 40Gb/s DWDM system with G.655 using NRZ-DPSK and NRZ-DQPSK modulation formats. A simulation is implemented to compare the dispersion and nonlinearity performance of these two methods, and it is found that pre-compensation performances better than section-by-section-compensation. The usage of pre-compensation will obtain better transmission capability in future 40Gb/s DWDM system with 50GHz channel-spacing.
