【摘要】：随着新技术新材料的不断涌现,当今市场瞬息万变,顾客需求不断升级,企业之间的竞争程度加剧。在国外随着光纤接入技术从有源到无源的巨大转型,“光进铜退”的宽带接入理念也在日益深入人心。无源光网络(PON)技术经历了从APON/BPON到EPON/GPON的发展,也趋于成熟。它具有无限的带宽和较大的传输容量,可避免电磁干扰,且传输介质普遍,安全性高不容易被窃取.光网络是信息时代的主导尤其是无源光网络更是节约了有源设备的投入与复杂性和供电不方便,避免单点故障,可提高系统可靠性。国内组网方式主流是EPON(以太无源光网络),就是通过OLT-OBD-ONU组成的网络结构,可承载以太网,语音,视频,以及高清数码有线电视等业务,可兼容xDSL。本文通过对光纤接入的概念的理解,和对互联网技术、通信需求增长的分析,结合用户和配电设备的优点和缺点,开展光纤网络的结构设计,以确定网络拓扑的发展。根据PON网络结构图确定所选择设备类型,计算所述光网络单元设备的位置、数量和距离,选择光器件,完成布线工艺和通过验收规范。本文包括六个部分。第一部分是绪论,分析了研究的背景,阐述了研究的目的和意义。第二部分对无源光网络PON进行了介绍,描述了光纤接入网的基本概念、基本构成、网络结构和层级结构,提出设计思路并以案例说明PON光纤接入网的解决方案。第三部分是ODN组网设计的研究方法,对理论内容,模型和层次结构做了相应地回顾。第四部分说明了PON光纤接入网的光器件选用。第五部分是光纤接入网的布线工艺及验收规范,以及性能测试结果。最后是结束语,总结归纳和展望。
[Abstract]:With the continuous emergence of new technologies and materials, the market is changing rapidly and customer demand is constantly upgrading. The degree of competition between enterprises is increasing. With the great transformation of optical fiber access technology from active to passive abroad, the broadband access concept of "optical access and copper retreat" is becoming increasingly popular. The passive optical network (PON) technology has experienced the development from APON/BPON to EPON/GPON. It also tends to mature. It has unlimited bandwidth and large transmission capacity, can avoid electromagnetic interference, and the transmission medium is universal, High security is not easy to be stolen. Optical network is the dominant in the information age, especially the passive optical network, which saves the input and complexity of active equipment and is inconvenient for power supply, and avoids single point fault. EPON (Ethernet passive Optical Network) is the network structure formed by OLT-OBD-ONU, which can carry Ethernet, voice, video, high-definition digital cable television and other services. XDSL.Through the understanding of the concept of optical fiber access, and the analysis of Internet technology and communication demand growth, combined with the advantages and disadvantages of users and distribution equipment, this paper develops the structure design of optical fiber network. In order to determine the development of network topology, according to the PON network structure diagram to determine the selected device type, calculate the location, number and distance of the optical network unit equipment, select the optical device, This paper includes six parts: the first part is introduction, the background of the research is analyzed, and the purpose and significance of the research are expounded. The second part introduces the passive optical network (PON). This paper describes the basic concept, basic structure, network structure and hierarchical structure of optical fiber access network, puts forward the design idea and illustrates the solution of PON optical fiber access network with a case study. The third part is the research method of ODN network design, and the theoretical content is discussed. The model and hierarchy are reviewed accordingly. In the fourth part, the optical device selection of PON fiber access network is described. The fifth part is the wiring process and acceptance specification of the optical fiber access network, as well as the performance test results. Finally, the conclusion is given. Summary and prospect.
