随着人们生活水平的不断提高和人们生活内容的不断改变,现阶段网络视频点播、网络电视直播、可视电话等宽带应用业务开始出现在人们的日程生活中。同时,社会大众对于宽带接入网提出了更高的要求。现如今,电信业的发展方向已经集中在了网络融合这一关键技术上。EPON系统正是由于其高宽带、低成本的优势,已经占据了有线接入市场一大部分比例,WiMAX系统的接入便捷性,已经成为无线接入市场的最佳选择。文章针对已有的PON网络规划进行研究,同时对PON与WiMAX融合接入网络规划也进行了较为系统的分析。
With the continuous improvement of people’s living standard and the constant change of people’s living content, broadband application services such as online video on demand, live webcast and video phone are beginning to appear in people’s daily life. At the same time, the community has put forward higher requirements for broadband access networks. Nowadays, the development direction of telecommunication industry has been focused on the key technology of network integration. Because of its advantages of high bandwidth and low cost, EPON system has occupied a large proportion of wired access market and access convenience of WiMAX system has become the best choice for wireless access market. In this paper, the existing PON network planning is studied, and the PON and WiMAX converged access network planning are also analyzed systematically.
