接入网技术与研究? [摘要] 随着现代通信技术、计算机网络技术以及信息产业的高速发展，接入网技术成为人们关注的焦点，并且是公司组建数字化、信息化网络首先考虑的问题。目前的接入网技术总体可分为有线接入网和无线接入网两种，本课题通过对各种接入网技术的比较，分析了几种接入技术，如ADSL接入网、混合光纤同轴电缆接入网，无线接入网，光接入网等进行了分析和比较，然后对ADSL接入技术中的ADSL做了详细的分析，在文章的最后，从发展的角度，对宽带接入网当前存在的问题和应用前景作了探讨。?[关键词]接入网；接入网技术；ADSL；接入网的发展；? Access network technology and research ?Tutor:???[Abstract] With modern communication technology, computer network technology and the rapid development of information industry, access network technology as the focus of attention, and the company set up digital information network the first consideration. The current access network technology in general can be divided into wired access networks and wireless access networks of two, this issue through the comparison of the various access network technologies, analysis of several access technologies such as ADSL access network, hybrid fiber coaxial cable connected network, radio access network, optical access network are analyzed and compared, then the ADSL ADSL access technology to do a detailed analysis. At the end of the article, from the perspective of the development of the broadband access, the existing problems and application prospects were discussed.?
