摘要

国际电信联盟(ITU)最近将超高清电视(UHD-TV)标准化，其分辨率是目前高清晰度电视的16倍。无源光网络(PON)需要提高视频源编码的效率或传输通道的容量来传输这些节目。本文提出了10G-PON (XG-PON)与单载波直调双二进制40G-PON (XLG-PON)信号完全无源共存的高容量集成PON基础设施，用于覆盖超高清电视。仿真结果表明，在20公里的双向标准单模光纤中，该方法具有良好的无差错传输性能，可以在广播的基础上以可忽略的功率损失进一步分配到32个光网络单元(onu)。

A Viable Passive Optical Network Design for Ultrahigh Definition TV Distribution

International Telecommunication Union (ITU) has recently standardized ultrahigh definition television (UHD-TV) with a resolution 16 times more than the current high definition TV. An increase in the efficiency of video source coding or in the capacity of transmission channels will be needed to deliver such programs by passive optical network (PON). In this paper, a high capacity integrated PON infrastructure is proposed to overlay ultrahigh definition television by a complete passive coexistence of 10G-PON (XG-PON) and single carrier directly modulated, duo-binary 40G-PON (XLG-PON) signal. The simulation results show error-free transmission performance and further distribution to 32 optical network units (ONUs) on broadcast basis with negligible power penalty over 20 km of bidirectional standard single mode fiber.
