摘　　要：运营商充分利用好PON和4G的各自优势,建立PON+LTE的融合宽带网络,可以实现优势互补,为用户提供体验一致的高速宽带接入服务。本文详细分析了在下一代无源光接入网中将LTE小基站信号和高速有线宽带信号混传的技术。仿真结果显示,在下一代无源光接入网的备选技术正交频分复用无源光接入网中混传无线LTE信号和高速有线宽带信号,可以省去无线信号的上下变频处理,技术实现简单,可以提升接入信号的多样性和速率。For telecommunications operators, making full use of the advantages of PON and 4 G respectively, can construct a converged broadband network and provide high-speed broadband access services to users. In order to meet the large-scale deployment of 4 G small stations and the increasing demand for wired access speed, the heterogeneous access technology of LTE signals and high-speed wired broadband signals in NG-PON2 was analyzed in this paper. The simulation results show that the orthogonal frequency division multiplexing PON(OFDM-PON, NG-PON2 alternative technology) with hybrid LTE signal and highspeed wired broadband signal can omit the wireless signal up and down frequency conversion processing and improve the access signal diversity and rate.
