【摘要】：隨著用戶網(wǎng)絡(luò)帶寬需求的不斷增長，全球電信運營商都在探尋轉(zhuǎn)型的最佳方法。在原有網(wǎng)絡(luò)上怎樣提供更多的業(yè)務(wù)，來提升企業(yè)的競爭能力，增加業(yè)務(wù)收入；怎樣將多種業(yè)務(wù)進(jìn)行融合銷售，降運行維護(hù)成本；怎樣使用戶對網(wǎng)絡(luò)倍感滿意，提高用戶黏性，達(dá)到降低離網(wǎng)率的目的，以上都是各家運營商需要亟待解決的問題。但是，現(xiàn)有的XDSL技術(shù)對于上述問題都難以得到解決辦法，另外最讓各家運營商頭痛還是現(xiàn)有網(wǎng)絡(luò)傳輸距離與帶寬之間的矛盾，因此，業(yè)界目前有一個解決問題共同答案就是：“光進(jìn)銅退”，采用光纖接入方案。 無源光網(wǎng)絡(luò)PON技術(shù)已經(jīng)成為當(dāng)前寬帶接入網(wǎng)的主流技術(shù)，盡管還有其他類似技術(shù)，比如APON/BPON和EPON等，但GPON (Gigabit-Capable Passive OpticalNetwork，吉比特?zé)o源光網(wǎng)絡(luò))技術(shù)仍然是無源光網(wǎng)絡(luò)(PON)家族中一個重要的組成部分。 GPON技術(shù)所具有的更高帶寬，更大分光比，更高發(fā)射功率等優(yōu)勢，無疑能夠解決“傳輸距離與帶寬矛盾”的問題，因此GPON技術(shù)必將成為當(dāng)前最受關(guān)注的光接入技術(shù)。 接入網(wǎng)是最靠近終端用戶的一層網(wǎng)絡(luò)，基于GPON技術(shù)進(jìn)行接入網(wǎng)建設(shè)，通過GEM適配等方法，不但可以能夠滿足現(xiàn)有的業(yè)務(wù)需求，還能夠支持將來許多新業(yè)務(wù)的應(yīng)用，如存儲域網(wǎng)(SAN)、數(shù)字視像等。GPON為各種業(yè)務(wù)需求提供了一條清晰的傳輸途徑，目前是實現(xiàn)光纖寬帶接入最有優(yōu)勢的技術(shù)之一，隨著GPON技術(shù)及應(yīng)用的快速發(fā)展，它已經(jīng)成為國際范圍內(nèi)的熱點技術(shù)之一。 錦州市電信公司也在積極探索和實施基于GPON技術(shù)的接入網(wǎng)建設(shè)，在基于GPON技術(shù)的接入網(wǎng)設(shè)計和實施工作中，將錦州市電信公司的現(xiàn)有網(wǎng)絡(luò)資源、網(wǎng)絡(luò)現(xiàn)狀和基于GPON技術(shù)的接入網(wǎng)建設(shè)項目進(jìn)行整理、分析來撰寫本論文。 論文首先介紹了基于吉比特技術(shù)無源光網(wǎng)絡(luò)(GPON)的概念、網(wǎng)絡(luò)結(jié)構(gòu)、工作原理及關(guān)鍵技術(shù)，分析出GPON技術(shù)應(yīng)用到錦州電信接入網(wǎng)的技術(shù)優(yōu)勢。 結(jié)合錦州電信現(xiàn)有網(wǎng)絡(luò)的現(xiàn)狀，提出錦州電信基于GPON技術(shù)的接入網(wǎng)建設(shè)總體方案，包括OLT的設(shè)置，，原有機(jī)房資源的利用，分光器的設(shè)置，現(xiàn)有ADSL小區(qū)的改造方式，針對不同性質(zhì)用戶FTTX的建設(shè)模式等。 本論文的重點是介紹基于GPON技術(shù)的幾種應(yīng)用場景，總結(jié)了目前基于GPON技術(shù)的FTTx接入網(wǎng)建設(shè)的應(yīng)用模型，通過分析光纖用戶接入網(wǎng)的現(xiàn)狀和不同用戶的業(yè)務(wù)需求，提出了基于GPON技術(shù)的錦州電信接入網(wǎng)絡(luò)建設(shè)策略和原則。通過研究錦州寶地晟麗花園、石化新區(qū)和杏花里住宅小區(qū)的實際建設(shè)場景，給出基于GPON技術(shù)的在上述小區(qū)接入網(wǎng)設(shè)計、實施方案及完成情況。總結(jié)基于GPON技術(shù)的接入網(wǎng)項目在用戶容量、投資情況、應(yīng)用主要設(shè)備和經(jīng)濟(jì)效益等方面的評價指標(biāo)和總體運行情況，通過建設(shè)項目的經(jīng)濟(jì)效益分析，證明了在建設(shè)成本上比ADSL接入方式更加經(jīng)濟(jì)合理，在維護(hù)方式、維護(hù)費用方面，較原有的ADSL網(wǎng)絡(luò)具有較大的優(yōu)勢，實現(xiàn)了減小維護(hù)工作量，降低維護(hù)費用的目的。 本文最后通過對GPON技術(shù)在接入網(wǎng)FTTH中應(yīng)用的分析，及未來應(yīng)用技術(shù)的分析和展望，給出基于GPON技術(shù)的接入網(wǎng)設(shè)計及實現(xiàn)的發(fā)展前景。隨著光源器件等設(shè)備成本的不斷下降，在大帶寬業(yè)務(wù)需求的驅(qū)動下，未來會有更好的技術(shù)應(yīng)用到FTTH接入網(wǎng)的建設(shè)中，比如10G GPON、波分無源光網(wǎng)絡(luò)（WDM-PON）等先進(jìn)技術(shù)將得到越來越多的應(yīng)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.
