摘要
随着宽带接入网络光纤化改造的逐步完成,DSLAM、小区LAN、PSTN等设备陆续退网,未来宽带接入网将统一采用PON技术组网,形成以FTTH为主,PON+LAN为辅的网络结构。OLT设备成为宽带接入网的核心设备,其设备性能和演进策略对宽带接入网的发展起着至关重要的作用。分析了OLT设备的现网部署情况、10G PON技术和OLT设备的发展趋势,结合业务需求,对10G PON的技术应用和OLT设备的部署提出了建议。
In recent years, the fiber optic renovation for broadband network has been gradually completed. With the equipment has been eliminated, such as DSLAM, LAN and PSTN, broadband network will unified use PON technology in the future. Meanwhile, the network is mainly composed of FTTH, supplemented by PON+LAN. OLT becomes the core of broadband network. Equipment performance and evolution strategy of OLT play an important role in the development of broadband network. Based on the analysis of OLT devices in the current network, 10G PON technology and the development of OLT devices, combining business requirements, it proposes some suggestions on the application of 10G PON and the deployment of OLT equipment.
