【摘要】 随着我国电信行业的飞速发展，运营商已经进入了全业务时代。中国移动和中国铁通由于政策的限制无法进行全业务经营，造成部分宽带和手机用户的流失。为了应对竞争，提高自身的竞争力，铁通实施了城域网改造工程。本论文结合铁通廊坊城域网改造工程的实施，深入研究了GPON技术，设计并组织实施了GPON技术在铁通廊坊城域网改造工程中的应用。具体工作有以下几点：首先，分析了运营商的在新一轮的电信重组后的现状。中国电信和中国联通凭借其牌照的优势，用有线宽带绑定手机的方式抢占国内电信市场。而中国移动和中国铁通由于政策的限制无法进行全业务经营，在竞争中处于劣势，从而造成部分宽带和手机用户的流失。在这种环境下，企业为了生存与发展必须不断创新来应对竞争。其次，对GPON的原理和GPON的技术等特性进行了分析，指出GPON的优势与不足。分析了GPON的多种接入方式（GPON+AD、GPON+LAN、GPON+FTTH、GPON+WBS），分析廊坊铁通城域网改造中应用GPON技术的可行性与经济性。再次，给出廊坊铁通城域网改造工程的设计方案，从实际出发，结合廊坊铁通的网络现状，选择合适的接入模型，分别针对农村用户、普通社区用户、高档小区用户、偏远山区用户进行了具体接入模型的分析。最后，对廊坊铁通城域网改造后的效果进行了评估。，本工程中体现的内容实用性强，节约了建设成本，提升了用户体验，实现了三网融合，克服了最后500m基础接入资源及应用模型上的缺乏。建全了自己的接入网并丰富了场景的模型，表明了铁通业务存在的合理性。在日后的竞争中保有一席之地。更多还原

【Abstract】 With the rapid development of China’s telecommunications industry, operators haveentered the area of the whole business. China Mobile and China Railcom policy can not bedue to limitations whole business, resulting in some loss of broadband and mobile phoneusers. In response to competition, to improve their competitiveness and theimplementation of the CRC MAN renovation project. This paper combines theimplementation of the CRC Langfang MAN renovation project, in-depth study of theGPON technology, design and implement the GPON technology in Langfang RailwayMAN reconstruction project. Concrete work are the following:Firstly, the status of operators in the new round of telecom restructuring wasanalyzed，China Telecom and China Unicom, with the advantage of its license, bound withcable broadband phone way to seize the domestic telecom market. China Mobile andChina Railcom policy can not be due to limitations whole business, at a disadvantage inthe competition, resulting in partial loss of broadband and mobile phone users. In thisenvironment, companies must develop in order to survive and continue to innovate torespond to competition.Secondly, the principles of GPON technology and other characteristics were analyzed,pointing out the advantages and disadvantages of GPON. Analysis of a variety of GPONaccess (GPON+AD, GPON+LAN, GPON+FTTH, GPON+WBS), analyzes theapplication of Langfang Railway MAN reconstruction GPON technology feasibility andeconomy.Then, given the design Langfang Railway MAN reconstruction project, from reality,combined with the status quo Langfang Railway network, select the appropriate accessmodel, respectively, for rural users, the general community of users, high-end residentialusers, users in remote mountainous areas analysis of the specific access model.Finally, the effect of Langfang Railway MAN after transformation were assessed.This project reflects the contents of the practical, saving construction costs and enhancethe user experience, to achieve the triple play, the last500m to overcome the lack ofaccess to basic resources and application model. Built his whole access network andenriched model of the scene, indicating the existence of rationality CTT business. Retain aplace in the future competition.更多还原
