构建NGB多业务PON融合网络

根据广电运营商业务发展的需要,结合天威视讯网络现状,提出了适合广电行业的多业务融合无源光网络架构.由于PON技术在广电接入网方面具有突出的优势,在现有网络上构建满足多业务要求的融合PON网络将影响深远.介绍了多接入方式并存的PON融合网络架构.最后,分析如何在融合PON网络平台开展基础业务、增值业务和ICT业务.为广大广电运营商推进光网的双向改造提供了参考.

Construction of NGB multi-service integrated PON network

According to the needs of the development of CATV operators, this article proposed a multi-service integrated passive optical-network architecture which based on the current situation of Topway network. As the PON technology in the access network had a prominent advantage in the existing network, that would be far-reaching impact to build a multi-service requirements of the integrated PON network.This article introduced the PON integrated network architecture with the coexistence of the multiple access network.Finally, we analyzed how to conduct basic services, value-added services and ICT services based on the integrated PON platform. This article provided a reference for the majority of CATV operators to upgrading the network.
