【摘要】:由于近年來(lái)通信技術(shù)的飛速發(fā)展,通信網(wǎng)絡(luò)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(shí)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(shù)成為制約整個(gè)網(wǎng)絡(luò)寬帶化和用戶(hù)體驗(yàn)進(jìn)步的瓶頸,從長(zhǎng)遠(yuǎn)上來(lái)說(shuō),唯一能解決這一瓶頸問(wèn)題的技術(shù)手段就是光接入技術(shù)!肮膺M(jìn)銅退”是由中國(guó)電信提出的基于無(wú)源光網(wǎng)絡(luò)(PON)技術(shù)實(shí)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(shè)備。PON技術(shù)作為一種新興的寬帶接入方式,由于其能夠提供光網(wǎng)絡(luò)的優(yōu)勢(shì)帶寬,可以完全滿足現(xiàn)在或者可以預(yù)見(jiàn)的未來(lái)各種寬帶和其他業(yè)務(wù)的需要,且在設(shè)備成本及運(yùn)維管理開(kāi)銷(xiāo)方面費(fèi)用相對(duì)較低,使得全面推進(jìn)光接入成為可能。陜西電信對(duì)于“光進(jìn)銅退”工程建設(shè)及改造的進(jìn)度在全國(guó)是位于前列的,由此接入網(wǎng)光進(jìn)銅退技術(shù)實(shí)現(xiàn)與應(yīng)用的研究對(duì)于本省乃至全國(guó)光進(jìn)銅退的進(jìn)一步推進(jìn)具有理論及現(xiàn)實(shí)的雙重意義。 本文的研究?jī)?nèi)容主要包括以下幾個(gè)方面:首先,對(duì)寬帶接入網(wǎng)層面的技術(shù)現(xiàn)狀進(jìn)行了初步研究,介紹了“光進(jìn)銅退”的基本觀點(diǎn);其次,對(duì)光纖到戶(hù)/光纖到樓(FTTH/FTTB)的理論,E/GPON技術(shù)原理、關(guān)鍵技術(shù)進(jìn)行了對(duì)比研究;第三,對(duì)陜西電信“光進(jìn)銅退”建設(shè)策略進(jìn)行了研究,包括“光進(jìn)銅退”改造前銅纜現(xiàn)狀調(diào)研、業(yè)務(wù)需求分析、光線路終端(OLT)、光分配網(wǎng)絡(luò)(ODN)部署,通過(guò)FTTB及FTTH實(shí)際應(yīng)用案例分析,得出陜西電信“光進(jìn)銅退”改造主要采用FTTH形式進(jìn)行的結(jié)論;第四,結(jié)合陜西實(shí)際情況給出FTTX網(wǎng)絡(luò)建設(shè)方案;最后詳細(xì)介紹了五十三中家屬院光進(jìn)銅退實(shí)現(xiàn)方案,并搭建了測(cè)試環(huán)境,從線路、網(wǎng)絡(luò)、語(yǔ)音等方面進(jìn)行測(cè)試,利用多種主流應(yīng)用及實(shí)際通話測(cè)試整體網(wǎng)絡(luò)速度和語(yǔ)音質(zhì)量,驗(yàn)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.
