摘要
对含有光纤光栅和光环形器的DWDM(密集波分复用)环网存在的串扰进行了分析,得到了评价串扰性能的指标(功率恶化、网络吞吐量)的数学模型,并将此模型图形化,联系图形得出了功率恶化、吞吐量与节点个数、节点损耗、串扰系数、发射功率、比特率等因素的关系。得出的结论对于DWDM环网的网络构建和性能改良有着重要的现实指导意义。
Through the performance analysis of DWDM ring with Optical Add - Drop Multiplexer （OADM） based on fiber grating and optical circulators, mathematic model of the indexes to evaluate the crosstalk pertormance, namely power penalty and throughput, is established. We also describe the model with graphs and draw a conclusion：to get a network with excellent performance, proper optical power, the number of nodes,the loss in every node and bit rate are needed. The conclusion is helpful to built and improve a DWDM ring network.
