1.FTTx时代已经到来:在当前新型业务日益丰富、带宽需求快速增长的趋势下,光纤接入(FTTx)是业界公认的接入网发展方向,拥有诸多无可比拟的技术优势。其中,PON(无源光网络)技术以其树形拓扑结构可以大幅度节约线路成本、维护成本低廉、业务提供能力强等优势成为FTTx的首选实现技术,其中EPON技术已经完全成熟,正在步入规模商用阶段。具有海量带宽和多业务承载能力的EPON光纤接入技术必将取代传统铜线成为接入网技术的主流。
1. FTTx era has arrived: FTTx is recognized as the development direction of access network in the current trend of new types of services and rapid growth in bandwidth demand. It has many incomparable technical advantages. Among them, PON (Passive Optical Network) technology with its tree topology can significantly reduce the cost of the line, low maintenance costs, the ability to provide business and other advantages of FTTx become the preferred implementation technology, EPON technology which has been fully mature, is entering Scale commercial stage. EPON optical access technology with massive bandwidth and multi-service bearer capability will surely replace traditional copper wire as the mainstream of access network technology.
