ASON传输系统调制特性的研究
Research on Modulation Characteristics in ASON Transmission System
摘要
Abstract
Under the mode of Internet plus,Quality of service(QoS)of Intelligent optical network(ASON)which carry large data due to self phase modulation(SPM)and cross phase modulation(XPM)will be decreased significantly. This paper firstly ana?lyzes the causes and effects of the modulation problem in the medium transmission system,and then expounds the modulation mecha?nism by using mathematical model from the mechanism of optical carrier transmission. In order to objectively indicate the impact of the modulation characteristics in the ASON transmission system,the system simulation is carried out by setting the corresponding parameter,and thus further,the relationship is given between modulation characteristics and the channel number & transmission distance. Finally,five solutions to overcome modulation characteristics are proposed in this paper.关键词
