ASON传输系统调制特性的研究
|
摘要
互联网+模式下,以光纤作为介质的智能光网络(ASON)在承载大数据时由于受到自相位调制(SPM)和交叉相位调制(XPM)的影响,业务质量(QoS)显著降低。论文首先分析介质传输系统中引发调制问题的相关原因及其影响,再从光载波传输机理出发运用数学模型阐述调制机理。为了客观地说明ASON传输系统受到调制特性影响的严重程度,论文通过设置相应参数进行系统仿真,并由此进一步给出传输距离、信道数量与调制特性之间的关系。最后提出五种克服调制特性的解决方案。
Under the mode of Internet plus,Quality of service(QoS)of Intelligent optical network(ASON)which carry largedata due to self phase modulation(SPM)and cross phase modulation(XPM)will be decreased significantly. This paper firstly analyzes the causes and effects of the modulation problem in the medium transmission system,and then expounds the modulation mechanism by using mathematical model from the mechanism of optical carrier transmission. In order to objectively indicate the impact ofthe modulation characteristics in the ASON transmission system,the system simulation is carried out by setting the correspondingparameter,and thus further,the relationship is given between modulation characteristics and the channel number & transmissiondistance. Finally,five solutions to overcome modulation characteristics are proposed in this paper.
