摘　　要：设计实现了基于宽光源频谱分割密集波分复用无源光网络(DWDM-PON)的实验系统。针对于相邻信道和非相邻信道串扰,通过串扰理论模型分析、系统实验测试得出的丢包率和光谱图比较了二者的影响;对比了理论和实验中DWDM-PON系统的串扰功率代价。结果表明:在信道间隔为0.8nm、速率为125Mbit/s的情况下,相邻信道串扰带来的光功率代价约为0.2dB;相邻信道引起的串扰远大于非相邻信道引起的串扰,非相邻信道引起的串扰影响可以忽略。An experimental system for spectrum-spliced dense wavefength division multiplexed passive optical network(DWDM-PON)based on broadband light source(BLS)is proposed.We compare the different effects of crosstalk in adjacent channel and non-adjacent channel based on the theoretical calculation as well as the experimental packet loss rate and frequency spectrum.We also fox the theoretical and the experimental crosstalk power penalty.The results show that at the 0.8nm channel spacing,125Mbit/s per channel,the pow...
