摘要
根据IPQAM系统的技术特点,搭建模拟环境,分别测试IPQAM信号和数字电视信号电耦合、IPQAM信号和数字电视信号在EDFA后光耦合、IPQAM信号和数字电视信号在EDFA前光耦合方式的输出指标情况,并提出IPQAM信号插播方案和具体输入输出指标要求。
According to the technical features of IPQAM system,builds the simulation environment,respectively IPQAM signals and test digital TV signals electrical coupling,IPQAM signals and digital TV signals in optical coupling,IPQAM EDFA after signals and digital TV signals in the way of EDFA former optical coupling situation output index.Put forward IPQAM signal breaks plan and specific input/output index requirements.
