摘　　要：为降低光线路终端和光网络单元光电器件的部署成本,基于现有成熟的10G-class光电器件,采用超奈奎斯特(FTN)窄带传输技术成功实现4×25Gb/s不归零码(NRZ)信号的100G下一代无源光网络(NG-PON2)传输。通过仿真和离线实验验证:基于FTN的窄带传输技术进行NRZ传输,在O波段可以实现单模光纤(SMF)20km传输,接收灵敏度可以达到-25.8dBm,且可以实现大于33dBm的功率预算。该系统方案满足NG-PON2的功率预算要求,实现与上一代PON系统的兼容设计。In order to reduce the deployment cost of optoelectronic devices in optical terminal and optical network unit,the existing mature 10G-class optoelectronic devices,and the next generation passive optical network(NG-PON2) transmission of 4×25 Gb/s non-return-to-zero(NRZ) line code signal is successfully realized by using faster-than-nyquist(FTN) narrowband transmission technology.Through simulation and off-line experiment,it is proved that the narrowband transmission technology based on FTN can realize 20 km transmission of single mode fiber(SMF) in O-band.Meanwhile,the receiving sensitivity can reach -25.8 dBm,and the power budget can be greater than 33 dBm.The scheme of the system meets the power budget requirements of NG-PON2 and achieves compatible design with the previous generation PON system.
