1、摘要編號淮安信息職業(yè)技術(shù)學院畢業(yè)論文題目典型寬帶接入技術(shù)的比較與應用學生姓名張偉學號37011310系部計算機與通信工程學院專業(yè)通信技術(shù)班級370113指導教師顧問教師二〇一三年十月摘要摘要隨著社會經(jīng)濟的發(fā)展，人們對各種新業(yè)務特別是寬帶綜合業(yè)務的需求日益增加，一系列接入網(wǎng)新技術(shù)應運而生，其中包括應用較廣泛的以現(xiàn)有雙絞線為基礎的銅纜新技術(shù)、混合光纖/同軸(HFC)、網(wǎng)技術(shù)和混合光纖/無線接入技術(shù)、無線本地環(huán)路技術(shù)(WLL/DWLL)及以太網(wǎng)到戶技術(shù)。寬帶接入技術(shù)的新的發(fā)展趨勢，不但建網(wǎng)開通快、維護簡單、用戶較密時成本低，而且改變了本地電信業(yè)務的傳統(tǒng)
2、觀念，最適于新的電信競爭者開展有效的競爭。本文敘述ADSL、以太網(wǎng)、光纖、FTTP等當前主流寬帶接入技術(shù)，分析了每種技術(shù)的特點和具體應用場合，并對寬帶接入技術(shù)發(fā)展進行了比較。關(guān)鍵詞：寬帶接入技術(shù)各種寬帶技術(shù)的比較接入技術(shù)的應用摘要AbstractWiththedevelopmentofsocietyandeconomy,peopleofallkindsofnewbusinessespeciallybroadbandintegratedservicesandincreasingdemand,emergeasthetimesrequireaserie
