【摘要】：90年代以后,密集波分复用技术获得了极快的发展速度,并由此推动了光纤通信向更高级的层次发展。光纤作为未来的通信领域、信息领域的重要传输基础,其重要性不言而喻。目前亟待解决的是,如何通过充分发挥光纤的带宽优势进而利用其广泛分布的传输资源,并最终推动宽带传送技术再一次提高。全光网(All Optical Network)作为一种端到端的全光路,其传输过程中是不存在光电转换、也没有光电转换器的,它的原理即是信号在从网中到用户节点之间的信号通道是一种光的形式,而不是光电依次转换性的方式进行信息传输。全光网有两个基本结构,分别是光网络层和电网络层。通常而言,光网络层一般是说光链路相连的那一部分,依赖与DWDM技术,可在同一光网中传输几个不同波长的光信号,其网格节点之间一般为光交叉连接设备(OXC)。不难发现,在以后的通讯业务、信息产业中,宽带网络有极大可能是全光网络与IP业务网相结合的大格局;基于这些光纤网络的技术,论文主要从以下几方面展开论述。首先,详细介绍了无源光网络的基本理论。本人在论文设计的初期,阅读了大量的国内国外有关于无源光网络的技术书籍与技术资料,从中了解到了当今无源光网络的最近技术。整个论文设计的无源光网络区别于传统的传输网络的技术优势主要体现在,全程光纤网络传输,传输距离长,网络带宽质量好,网络安全性好,承载多业务模式,光纤到户或到桌面。这些技术优势决定了,整个网络的设计与建设是与时俱进的,是符合现代网络技术快速发展潮流的。其次,基于当今通信网络技术的理论基础,在光纤网络全球大发展的时代背景下,提供FTTX的最优的解决方案,为用户提供方便,快捷,高速的网络访问体验,将各种网络设备优化,让它们发挥最大的效能,同时降低网络建设的成本,建立一套性价比很高的网络是本论文设计的核心思想。同时,论文中针对不同的应用场景进行不同的方案设计,充分利用现有的网络资源,在不进行大量的投资前提下,显著的提升网络效能,满足现代社会人们对于网络速度提升的要求。最后,对于全文的主要工作进行总结与展望
[Abstract]:Since the 1990s, dense wavelength Division Multiplexing (DWDM) technology has gained a rapid development speed, and thus promoted the development of optical fiber communication to a higher level. Optical fiber as the future communication field, information field of important transmission basis, its importance is self-evident. At present, what needs to be solved urgently is how to make full use of the bandwidth advantage of optical fiber and make use of its widely distributed transmission resources, and finally promote the broadband transmission technology to improve again. As an end to end all optical network, there is no photoelectric conversion and no photoelectric converter in the transmission process. Its principle is that the signal channel from the network to the user node is a form of light. Instead of optoelectronic sequential conversion of information transmission. All-optical network has two basic structures: optical network layer and electric network layer. Generally speaking, the optical network layer usually refers to the part of the optical link connected. Depending on the DWDM technology, it can transmit several optical signals of different wavelengths in the same optical network. It is not difficult to find that, in the future communication service and information industry, broadband network may be the combination of all-optical network and IP service network. Based on the technology of these fiber-optic networks, this paper mainly discusses from the following aspects. Firstly, the basic theory of passive optical network is introduced in detail. At the beginning of the thesis design, I read a lot of technical books and technical materials about passive optical network at home and abroad, from which I learned the latest technology of passive optical network. The technical advantages of the passive optical network designed in the whole paper are mainly reflected in the following aspects: the whole optical fiber network transmission, long transmission distance, good network bandwidth quality, good network security, and carrying multi-service mode. Fiber to the home or to the desktop. These technical advantages determine that the design and construction of the whole network is keeping pace with the times and is in line with the rapid development trend of modern network technology. Secondly, based on the theoretical foundation of communication network technology, in the background of the global development of optical fiber network, the optimal solution of FTTX is provided to provide users with convenient, fast and high-speed network access experience. The core idea of this paper is to optimize all kinds of network equipment, to make them exert maximum efficiency, at the same time to reduce the cost of network construction, and to establish a set of network with high performance and price ratio. At the same time, according to different application scenarios, the thesis designs different schemes, makes full use of existing network resources, and improves network efficiency significantly without a lot of investment. To meet the needs of modern society for the speed of the network. Finally, the main work of the full text is summarized and prospected.
