【摘要】：随着用户网络带宽需求的不断增长，全球电信运营商都在探寻转型的最佳方法。在原有网络上怎样提供更多的业务，来提升企业的竞争能力，增加业务收入；怎样将多种业务进行融合销售，降运行维护成本；怎样使用户对网络倍感满意，提高用户黏性，达到降低离网率的目的，以上都是各家运营商需要亟待解决的问题。但是，现有的XDSL技术对于上述问题都难以得到解决办法，另外最让各家运营商头痛还是现有网络传输距离与带宽之间的矛盾，因此，业界目前有一个解决问题共同答案就是：“光进铜退”，采用光纤接入方案。无源光网络PON技术已经成为当前宽带接入网的主流技术，尽管还有其他类似技术，比如APON/BPON和EPON等，但GPON (Gigabit-Capable Passive OpticalNetwork，吉比特无源光网络)技术仍然是无源光网络(PON)家族中一个重要的组成部分。 GPON技术所具有的更高带宽，更大分光比，更高发射功率等优势，无疑能够解决“传输距离与带宽矛盾”的问题，因此GPON技术必将成为当前最受关注的光接入技术。接入网是最靠近终端用户的一层网络，基于GPON技术进行接入网建设，通过GEM适配等方法，不但可以能够满足现有的业务需求，还能够支持将来许多新业务的应用，如存储域网(SAN)、数字视像等。GPON为各种业务需求提供了一条清晰的传输途径，目前是实现光纤宽带接入最有优势的技术之一，随着GPON技术及应用的快速发展，它已经成为国际范围内的热点技术之一。锦州市电信公司也在积极探索和实施基于GPON技术的接入网建设，在基于GPON技术的接入网设计和实施工作中，将锦州市电信公司的现有网络资源、网络现状和基于GPON技术的接入网建设项目进行整理、分析来撰写本论文。论文首先介绍了基于吉比特技术无源光网络(GPON)的概念、网络结构、工作原理及关键技术，分析出GPON技术应用到锦州电信接入网的技术优势。结合锦州电信现有网络的现状，提出锦州电信基于GPON技术的接入网建设总体方案，包括OLT的设置，，原有机房资源的利用，分光器的设置，现有ADSL小区的改造方式，针对不同性质用户FTTX的建设模式等。本论文的重点是介绍基于GPON技术的几种应用场景，总结了目前基于GPON技术的FTTx接入网建设的应用模型，通过分析光纤用户接入网的现状和不同用户的业务需求，提出了基于GPON技术的锦州电信接入网络建设策略和原则。通过研究锦州宝地晟丽花园、石化新区和杏花里住宅小区的实际建设场景，给出基于GPON技术的在上述小区接入网设计、实施方案及完成情况。总结基于GPON技术的接入网项目在用户容量、投资情况、应用主要设备和经济效益等方面的评价指标和总体运行情况，通过建设项目的经济效益分析，证明了在建设成本上比ADSL接入方式更加经济合理，在维护方式、维护费用方面，较原有的ADSL网络具有较大的优势，实现了减小维护工作量，降低维护费用的目的。本文最后通过对GPON技术在接入网FTTH中应用的分析，及未来应用技术的分析和展望，给出基于GPON技术的接入网设计及实现的发展前景。随着光源器件等设备成本的不断下降，在大带宽业务需求的驱动下，未来会有更好的技术应用到FTTH接入网的建设中，比如10G GPON、波分无源光网络（WDM-PON）等先进技术将得到越来越多的应用。
[Abstract]:Along with the increasing demand for bandwidth of network users, the global telecom operators are the best way to explore the transformation. How to provide more services on the original network, to enhance the competitive ability of the enterprise, increase business income; how will a variety of business integration sales, reduce operation and maintenance cost; how users feel satisfied with the network, improve the user viscosity, reduce churn rate to operators above are needed to be solved. However, the existing XDSL technology for the above problems are difficult to get the solution, in addition to the contradictions between the various operators headache or the existing network transmission distance and bandwidth so that the industry currently has a solution the answer is: "the common problem of copperquot, using optical fiber access scheme.
Passive optical network PON technology has become the mainstream technology of broadband access network, even though there are other similar technologies, such as APON/BPON and EPON, but GPON (Gigabit-Capable Passive OpticalNetwork, gigabit passive optical network) technology is still the passive optical network (PON) is an important part of the family. GPON technology has higher bandwidth the greater the splitting ratio, higher transmit power and other advantages, it can solve the transmission distance and bandwidth contradiction ", so GPON technology will become the most popular optical access technology.
The access network is a network layer closest to the end user, the access network construction based on GPON technology, through the GEM adapter and other methods, can not only be able to meet current business needs, but also can support the future application of many new businesses, such as storage area network (SAN), and provide a clear way of digital video transmission.GPON for a variety of business needs, is currently one of the most advantageous optical fiber broadband access technology, with the rapid development of GPON technology and application, it has become one of the hot technologies in the international scope.
Jinzhou telecom company is also actively exploring and implementing access network construction based on GPON technology, based on access network design and implementation of GPON technology in the existing cyber source Jinzhou City telecommunication company, the status quo of network and access network construction project based on GPON technology for processing, analysis to the writing of this thesis.
This paper first introduces the technology of gigabit passive optical network (GPON) based on the concept of network structure, working principle and key technology of the application of GPON technology to Jinzhou Telecom access network technology.
According to the present situation of Jinzhou Telecom's existing network, put forward overall scheme of Jinzhou Telecom Access Network Construction Based on GPON technology, including OLT settings, use the original room resources, splitter settings, renovation of existing residential ADSL, according to different user FTTX construction mode.
The focus of this paper is to introduce several application scenarios based on GPON technology, summarizes the current application model based on the construction of FTTx access network GPON technology, through the analysis of the status of optical fiber access network and different business needs of users, the GPON technology is put forward for Jinzhou Telecom Access Network Construction Strategy and based on the principles through the study of Jinzhou Sheng treasure. Li Garden, residential construction area and the actual scene of petrochemical apricot, given the community access network design based on GPON technology, implementation and completion. Summarize the access network project based on GPON technology in user capacity, investment, application of main equipment and economic benefits and other aspects of the evaluation index and the overall running situation. Through the analysis of the economic benefits of the construction project, the construction cost is proved in ADSL access way more economically and reasonably in maintenance mode, maintenance costs, Compared with the original ADSL network, it has great advantages to reduce the maintenance work and reduce the maintenance cost.
Finally, through the analysis of the application of GPON technology in the access network of FTTH, analysis and outlook and future application technology, gives the design of GPON access network technology and development prospects. Based on the realization of lighting devices with the declining cost of equipment, in driving large bandwidth business needs, the future will have better technology application the construction of FTTH access network, such as 10G GPON, WDM passive optical network (WDM-PON) and other advanced technology will be more and more.
