摘要
在三网融合的竞争中,广电网络已经处于落后的尴尬地位,面临着三大运营商的侵蚀,迫切需要一种快速高效的技术来改造现有网络,以大幅提升网络带宽,实现宽带、语音、视频全业务运营。WDM-PON技术结合WDM和PON技术的优点,将多路PON信号复用到同一根光纤中传输,不需要重新敷设光缆,极大节约了光纤资源,很适合当前的网络改造。
In the triple play competition,radio and television networks already in awkward position behind,facing three major operators in the electrical erosion,radio and television is an urgent need to a fast and efficient technology to transform the existing network,significantly enhance the network bandwidth,broadband,voice,video,the whole business operation ability. WDM- PON technology which is the combination of the WDM and PON technology advantages,will be a lot of PON signal multiplexing to the same root fiber transmission,do not need to re laying of fiber optic cable,greatly saving fiber resources,reduce construction period,it is suitable for the network transformation of a radio and television.
