光纤通信中新技术的发展研究 摘要 光纤通信自从问世以来，给整个通信领域带来了一场革命，它使高速率、大容量的通信成为可能。光纤通信由于具有损耗低、传输频带宽容量大、抗电磁干扰等优点而备受业内人士的青睐，发展非常迅速。目前它已经成为一种不可替代的的信息传输技术。这篇文章简要介绍了光纤通信的技术概述和现阶段应用光纤通信的基本情况，大致地总结了目前光纤通信主要技术— —光波分复用技术、光纤接入技术、光孤子通信技术和超大容量、超长距离传输技术的基本原理、优势、发展状况，最后具体详细论述了未来光纤通信将是朝着全光网络的方向发展，以全光网络为重点，结合现在通信发展，谈谈光纤通信技术的发展前景。 关键词 ：光波分复用 光纤接入 光孤子 全光网络 Title : the development of new technology research in Optical Fiber Communication . Abstract: Since the advent of fiber-optic communications,as a whole to bring about a revolution, communications makes high-speed, high-capacity communications possible. Since the loss optical fiber communication with low-frequency bandwidth transmission capacity, anti-electromagnetic interference, and so has advantages in the industry as a favor to develop very quickly. At present, it has become an irreplaceable information transmission technology. The article outlined the Optical Fiber Communication Technology and Application of fiber-optic communications at the present stage of the basic, more or less summed up the current main fiber-optic communications technology——optical wavelength division multiplexing technology, optical fiber access technology, optical soliton communication technology and large-capacity , Ultra-long-distance transmission of the basic principles of technical advantages, the development of the final details of the specific optical fiber communication in the future will be moving in the direction of all-optical network development in order to focus on all-optical network, now combined with the development of communication, to talk about the fiber-optic communication Prospects for the development of technology. keywords: Optical Wavelength Division Multiplexing Optical Access Optical soliton All-optical network 目录 1 引言 5 2 光纤通信技术概述 5 2.1 光纤通信的定义特点及应用领域 5 2.2 光纤通信的发展状况 6 3 光纤通信技术的现状及发展趋势 6 3.1 波分复用技术 6 3.2 光纤接入技术 7 3.3 光孤子通信 8 3.4 超大容量、超长距离传输技术 9 3.5 全光网络技术 9 4 全光网络基本原理 10 4.1 概念及优点 10 4.1.1 全光网的概念 10 4.1.2 全光网的优点 10 4.2 基本
