摘要
Current integrated application services,especially bi directional interactive service and data transmission service,launched over CATV network,make exact demands for the performance of network.The authors conducted researches on the relationship between performance indexes of HFC optical node and number of consumers,selected test points with 3 various consumer accesses for the reconstruction,and performed test,induction and analysis of all technical indexes before and after the reconstruction,thus providing a practical experience for fully popularizing the reconstruction of CATV network.
