发布时间：2019-03-18 14:19
【摘要】：由于近年来通信技术的飞速发展,通信网络的核心部分发生了巨大的变化,固网传输网的数字化和光纤化已基本实现,但是接入网部分发展则显得较慢,只适合传送话音的铜缆和传统交换技术成为制约整个网络宽带化和用户体验进步的瓶颈,从长远上来说,唯一能解决这一瓶颈问题的技术手段就是光接入技术。“光进铜退”是由中国电信提出的基于无源光网络(PON)技术实施固网接入光纤化、宽带化的重要举措,此举不仅可以取代接入铜缆,而且可以同步取代传统的话音交换程控设备。PON技术作为一种新兴的宽带接入方式,由于其能够提供光网络的优势带宽,可以完全满足现在或者可以预见的未来各种宽带和其他业务的需要,且在设备成本及运维管理开销方面费用相对较低,使得全面推进光接入成为可能。陕西电信对于“光进铜退”工程建设及改造的进度在全国是位于前列的,由此接入网光进铜退技术实现与应用的研究对于本省乃至全国光进铜退的进一步推进具有理论及现实的双重意义。 本文的研究内容主要包括以下几个方面：首先,对宽带接入网层面的技术现状进行了初步研究,介绍了“光进铜退”的基本观点；其次,对光纤到户/光纤到楼(FTTH/FTTB)的理论,E/GPON技术原理、关键技术进行了对比研究；第三,对陕西电信“光进铜退”建设策略进行了研究,包括“光进铜退”改造前铜缆现状调研、业务需求分析、光线路终端(OLT)、光分配网络(ODN)部署,通过FTTB及FTTH实际应用案例分析,得出陕西电信“光进铜退”改造主要采用FTTH形式进行的结论；第四,结合陕西实际情况给出FTTX网络建设方案；最后详细介绍了五十三中家属院光进铜退实现方案,并搭建了测试环境,从线路、网络、语音等方面进行测试,利用多种主流应用及实际通话测试整体网络速度和语音质量,验证了FTTH接入的有效性。
[Abstract]:due to the rapid development of the communication technology in recent years, the core part of the communication network has changed greatly, the digitization and the optical fiber transformation of the fixed network transmission network are basically realized, but the development of the access network part is relatively slow, Copper and traditional switching technology, which is only suitable for transmitting voice, becomes the bottleneck of the whole network broadband and user experience progress, and in the long run, the only technical means to solve the bottleneck problem is the optical access technology. "light in and out of the copper" is an important measure to implement fixed-network access and broadband based on passive optical network (PON) technology proposed by China Telecom, which not only can replace the access copper cable, but also can synchronously replace the traditional voice exchange program control equipment. The PON technology, as an emerging broadband access mode, can fully meet the needs of the current or foreseeable future various broadband and other services due to the advantage bandwidth of the optical network, and the cost is relatively low in terms of equipment cost and operation and maintenance management overhead, Such that the overall propulsion of optical access becomes possible. The progress of Shaanxi Telecom in "light in and out of the copper" engineering construction and transformation is in the forefront of the country, and the research on the realization and application of the access network light to the copper return technology has the dual meaning of theory and reality for the further advancement of the light in the province and even the whole country. The research contents of this paper mainly include the following aspects: firstly, the present situation of the broadband access network is initially studied, the basic point of view of the "light in and out of the copper" is introduced; secondly, the theory of the optical fiber to the home/ optical fiber to the building (FTTH/ FTTB) and the E/ GPON technology The paper makes a comparative study on the key technology and the key technology. The third part is to study the construction strategy of the telecommunication "light in and out of the copper" in Shaanxi, including the research on the current situation of the copper cable before the "light in and out of the copper", the analysis of business needs, the optical line terminal (OLT) and the optical distribution network (ODN), and the practical application case of FTTB and FTTH. In this paper, it is concluded that the transformation of the telecommunication "light in and out of the copper" in Shaanxi is mainly based on the form of FTTH. The fourth part, combining with the actual situation of Shaanxi, gives the construction scheme of FTTX network. Finally, the paper introduces the implementation of the light-in-and-back implementation of the home-owned house in the fifty-third, and sets up the test environment, from the line and the network. The test is carried out in the aspects of complex network, voice and the like, and the effectiveness of the FTTH access is verified by using a variety of mainstream applications and the overall network speed and voice quality of the actual call test.
