中文摘要: 无源光网络是解决光接入网络瓶颈的最佳方案,是推动当前我国三网融合政策的关键技术,其研究具有重要的科学和社会意义。本课题从下一代无源光网络(PON)高性能、高灵活性、低成本的需求出发,提出一种基于单载波频域均衡的无源光网络(SCFDE-PON)方案。SCFDE-PON相比OFDM-PON有更低的峰均比,从而降低了实现成本,并具有与传统TDM-PON高度兼容性。本课题重点研究SCFDE-PON的上/下行传输理论、高频谱效率调制物理限制、SCFDE-PON网络结构和高度自适应的动态带宽分配(DBA)策略等科学问题,最终建立面向100Gb/s SCFDE-PON双向离线实验平台与基于FPGA的10Gb/s双向SCFDE-PON实时实验平台,对理论研究成果进行实验验证。

英文摘要: The passive optical network (PON) is the best solution to remove the bottleneck of current optical access network. Also it is the key technique for the Tripple-play Strategy of China. The research of PON has much scientific and social significance. This project is to propose a PON scheme based on single-carrier frequency-domain equalization (SCFDE), which helps to achieve effective next-generation PON with high performance, high flexibility and low cost. The SCFDE-PON has lower peak-to-average power than the OFDM-PON to be cost-effective, also it has high compatibility with conventional TDM-PON. The project is to focus on some scientific problems for SCFDE-PON, such as theories of upstream/downstream transmission, physical limits of high-order modulation, network architecture and adaptive DBA strategy. The researchers aim to build a 100-Gb/s bi-directional offline experimental platform and a 10-Gb/s bi-directional real-time experimental platform. The theoretical research results will be verified on the two experimental platforms.
