摘要 设计并仿真分析了16路双向CSRZ-DPSK调制的40Gb/sDWDM系统,并采用对下行信号进行DP-SK再调制的方式产生上行数据信号。仿真结果显示此种方式在节省FTTH用户端发射成本的同时得到了比较理想的高速传输效果,在未来中国FTTH系统的推广中将是很有竞争力的解决方案。 Propose and simulate a 40Gb/s dense wavelength division multiplexed(DWDM) system, using Cartier-Suppressed Return-to-Zero differential phase-shift keying (CSRZ-DPSK) modulation format both in downstream and upstream signals .And the upstream signal is generated by re-modulating the downstream signal. Simulation results shows that the system not only decrease the cost of transmitter at the optical networking unit (ONU) but also have good performance. It will be a competitive solution in FTTH development in China.
