摘要
随着各种电信增值业务的发展,宽带越来越宽已经成为宽带发展的重要规律。在ADSL迅猛发展的同时,光纤接入已经开始进入市场启动阶段。基于此,分析了ADSL和FTTH的各种组网方式,比较了这两种接入技术的成本要素,并得出结论:ADSL属于过渡技术,而以EPON为基础的FTTH将是未来宽带接入技术发展的趋势。
With the development of so many value-added services, the rapid evolution in broadband demand is more and more popular. The ascendancy of FTTH （Fiber to the Home） in China will impact optical access identically much in the way of recent widespread deployment of DSL. The paper analyses different network building modes of ADSL and FTTH, compared with the cost element of these access technologies. Finally, it arrives at the conclusion that FTTH based on EPON （Ethernet passive Optical Network） will be the tendency in the future.
