1 Guangxi University of Science and Technology 接入網(wǎng)技術(shù)大作業(yè) 課題名稱(chēng) : 中國(guó)大陸接入網(wǎng)技術(shù)的現(xiàn)狀及發(fā)展前景 院 (系): 計(jì)算機(jī)學(xué)院 專(zhuān) 業(yè): 通信工程 班 級(jí): 通信 101 學(xué)生姓名: 劉金龍 學(xué) 號(hào): 202100402024 指導(dǎo)教師: 郭源源 2021 年 6 月 29 日 2 引言 所謂接入網(wǎng)是指 骨干網(wǎng) 絡(luò)到用戶(hù)終端之間的所有設(shè)備。其 長(zhǎng)度 一般為幾百米到幾公里,因而被形象地稱(chēng)為 最后一公里 。由于骨干網(wǎng)一般采用光纖結(jié)構(gòu),傳輸速度快,因此,接入網(wǎng)便成為了整個(gè)網(wǎng)絡(luò)系統(tǒng)的瓶頸。接入網(wǎng)的接入 方式 包括銅線(普通電話線)接入、光纖接入、光纖同軸 電纜 (有線電視電纜)混合接入、無(wú)線接入和 以太網(wǎng) 接入等幾種方式 。 關(guān)鍵詞 :接入網(wǎng) 3 Introduction The socalled access work is the backbone of the work to the user terminal all its length is generally a few hundred meters to several kilometers which is vividly called last mile fiber monly used as the backbone structure of the access work transmission speed will. therefore bee the bottleneck of the whole work system access work access methods, including copper (ordinary telephone line) access optical access fiber coaxial (cable TV cable) hybrid access ,wireless access and ether access, such as several way Keywords:access work 4 目錄 引言 ..............................................................................................................................................2 Introduction ....................................................................................................................................3 ............................................................................................................5 未來(lái)幾年內(nèi) ADSL2+/VDSL2 技術(shù)仍是主流的寬帶接入技術(shù) ..............................................5 / WiMAX 將作為重要補(bǔ)充手段滿足網(wǎng)絡(luò)和業(yè)務(wù)融合需要 ........................................5 .................................................................................................6 銅線接入 ..........................................................................................................................6 光纖接入網(wǎng)技術(shù) ................................................................................................................7 ............................................................................
