在当前三网融合的宏观环境下,有线电视网络面临着政策、技术、业务发展的重要转型,机遇与挑战并存,迫切需要做好双向网络建设,以提升网络对各类新业务、新业态的承载能力,增强企业核心竞争力。PON网络作为目前有线电视网络双向化改造的主要技术,是快速实现网络双向化改造,打造高品质、大容量、高效益的双向接入网的主用技术。ODN网络作为PON网络建设的重要基建环节,其投资占整个EPON系统建设投资的70%以上,因此ODN网络规划和设计直接影响着PON网络建设投资和质量。本文结合江苏省广播电视信息网络股份有限公司(以下简称“江苏有线”)EPON网络的建设和发展规划,分析介绍了EPON系统下ODN网络规划与设计中的重点问题及需遵守的相关原则。
Under the current macro-environment of triple play, cable television networks are faced with an important transformation in policy, technology and business development. Opportunities and challenges coexist. It is imperative to do a good job in building a two-way network in order to enhance the network’s capability in all kinds of new businesses and new formats Carrying capacity and enhance their core competitiveness. PON network as the current two-way cable television network transformation of the main technology is the rapid realization of two-way transformation of the network to create high-quality, large capacity, high efficiency of the main two-way access network technology. As an important infrastructure link in the construction of PON network, ODN network accounts for more than 70% of the total EPON system construction investment. Therefore ODN network planning and design directly affects the PON network construction investment and quality. This article combines the construction and development plan of EPON network of Jiangsu Radio and Television Information Network Co., Ltd. (hereinafter referred to as “Jiangsu Cable”), analyzes and introduces the key problems in ODN network planning and design under EPON system and the related principles to be observed .
