摘 要: 光纤到户(FTTH)一直是光接入网不断追求和探索的技术方向,随着用户对带宽需求的提高,技术的突破和新标准的确定以及光纤光缆及相关元器件价格的大幅度下降,FTTH出现迅速发展的势头,为此简述了FTTH走过的历程和现状,提出了实现FTTH的主要解决方案并进行了比较,同时对实现FTTH的关键技术作了分析。 FTTH is the certain development trends of optical access technology. With the increase of bandwidth demand, the breakthrough of technology, the development of standards and the drop of the device cost, FTTH is developing very fast. Therefore the evolution and latest trend of FTTH is described briefly, the main FTTH solutions, such as point to point Ethernet, EPON, GPON are analysed and compared. At the same time, the key techniques to realize FTTH are analysed.
