摘　　要：本文首先介绍宽带接入网的发展状况和主要应用,然后讲述宽带光纤接入网的主要优势,接下来详细分析了各种FTTH的技术特征与方案选择比较,着重指出各种FTTH技术都有其最佳使用场合和时机,其中点到点有源以太网光纤系统适合在低密度用户分散地区应用,点到多点无源光纤系统最适合新建或改建的密集用户区应用。我国的发展应跨越APON、BPON阶段,从宽带点到点以太网光纤系统和EPON开始,最终过渡到GPON阶段。This paper describes the status and major applications for broadband access networks and presents major strengths for broadband optical access networks. Then, the paper analyzes and compares major technical characteristics and solutions for different FTTH It is concluded that each FTTHtechnology has his own best application scenario and time. Among which the broadband point to point optical fiber Ethernet solution is fit for lower dense and disperse users area and the broadband point to multi-points passive optical fiber system solution is more suitable to dense populated area in green field and rehabilitated area. It is anticipated that China will be likely across APON and BPON, starts with broadband point to point optical fiber Ethernet and EPON and eventually transits to GPON.
