摘要
全业务时期不同业务的带宽需求给传统接入技术带来了压力,本文立足于未来接入网的发展趋势,系统分析和比较多种宽带接入方式的优劣,重点分析两种主流PON技术的性能优劣和布网成本等,得出PON技术在接入网引入的必要性并对引入策略做出初步探讨。
Nowadays, different applications require different bandwidths of the network. It challenges the traditional techniques of constructing Radio Access Network. Considering the trend of how the Radio Access Network will be developed in the future, we systematically analyzed and compared several different network accessing methods. In this paper, we focused on two mainstream PON techniques. We analyzed their advantages, disadvantages and construction cost. We found that it＇s necessary to introduce PON when constructing access network. Finally, we discussed the strategies for introducing PON.
