【摘要】:由于近年來通信技術的飛速發(fā)展,通信網(wǎng)絡的核心部分發(fā)生了巨大的變化,固網(wǎng)傳輸網(wǎng)的數(shù)字化和光纖化已基本實現(xiàn),但是接入網(wǎng)部分發(fā)展則顯得較慢,只適合傳送話音的銅纜和傳統(tǒng)交換技術成為制約整個網(wǎng)絡寬帶化和用戶體驗進步的瓶頸,從長遠上來說,唯一能解決這一瓶頸問題的技術手段就是光接入技術!肮膺M銅退”是由中國電信提出的基于無源光網(wǎng)絡(PON)技術實施固網(wǎng)接入光纖化、寬帶化的重要舉措,此舉不僅可以取代接入銅纜,而且可以同步取代傳統(tǒng)的話音交換程控設備。PON技術作為一種新興的寬帶接入方式,由于其能夠提供光網(wǎng)絡的優(yōu)勢帶寬,可以完全滿足現(xiàn)在或者可以預見的未來各種寬帶和其他業(yè)務的需要,且在設備成本及運維管理開銷方面費用相對較低,使得全面推進光接入成為可能。陜西電信對于“光進銅退”工程建設及改造的進度在全國是位于前列的,由此接入網(wǎng)光進銅退技術實現(xiàn)與應用的研究對于本省乃至全國光進銅退的進一步推進具有理論及現(xiàn)實的雙重意義。 本文的研究內(nèi)容主要包括以下幾個方面:首先,對寬帶接入網(wǎng)層面的技術現(xiàn)狀進行了初步研究,介紹了“光進銅退”的基本觀點;其次,對光纖到戶/光纖到樓(FTTH/FTTB)的理論,E/GPON技術原理、關鍵技術進行了對比研究;第三,對陜西電信“光進銅退”建設策略進行了研究,包括“光進銅退”改造前銅纜現(xiàn)狀調(diào)研、業(yè)務需求分析、光線路終端(OLT)、光分配網(wǎng)絡(ODN)部署,通過FTTB及FTTH實際應用案例分析,得出陜西電信“光進銅退”改造主要采用FTTH形式進行的結論;第四,結合陜西實際情況給出FTTX網(wǎng)絡建設方案;最后詳細介紹了五十三中家屬院光進銅退實現(xiàn)方案,并搭建了測試環(huán)境,從線路、網(wǎng)絡、語音等方面進行測試,利用多種主流應用及實際通話測試整體網(wǎng)絡速度和語音質(zhì)量,驗證了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.
