【摘要】：近十年来,下一代广播电视网络(Next Generation Broadcasting Network,NGB)正向着数字化、网络化、交互化、高清化和多业务方向发展,特别是在“三网融合”和“宽带中国”发展战略的时代大背景下,对原有的有线电视系统带来了极大的冲击和挑战。河南有线现有接入技术已经无法满足接入带宽的需求,未来关于接入技术选择中,光纤入户已成必然趋势。光纤接入技术拥有抗电磁干扰强,传输容量大和无限带宽等优势,同时还具备传输介质安全性高和不易窃取等特征。毫无疑问,光网络将是未来的主流网络接入技术,特别是无源光网络技术,它避免了供电不变、设备复杂、设备投入高等有源接入技术的不足之处,显著提高了网络传输系统的稳定性和可靠性。本论文以河南有线光纤入户改造为研究对象,结合现有广电行业新标准,归纳整理了现有有线电视光纤到户的组网方案,介绍了无源光纤网络(Passive Optical Network,PON)技术的参数、关键技术并分析了该技术的优劣势。进而立足于现有河南有线电视双向网络现状和广电网络未来发展趋势,为了保证网络开放性,可运营性,可管理性,可增值性等原则,提出了光纤入户(Fiber To The Home,FTTH)的技术方案。方案中将FTTH系统分成A、B双平面架构。A平面承载原有的数字电视广播通道及VOD点播通道,B平面承载基于EPON的数据通道,并且对接入容量及网络演进进行分析,最后对安阳熙城都会小区光纤入户项目进行分析,并对广电网络光纤到户的发展前景进行展望。
[Abstract]:In the past ten years, the next generation of broadcast television network (Next Generation Broadcasting Network, NGB) towards digitization, networking, interactive, high-definition and multi business development, especially in the background of "triple play" and "broadband Chinese" development strategy, has brought great shock and challenge the original cable TV system. Henan cable existing access technology has been unable to meet the demand for access bandwidth. In the future selection of access technology, fiber access has become an inevitable trend. Optical fiber access technology has the advantages of strong anti electromagnetic interference, large transmission capacity and unlimited bandwidth, and also has the characteristics of high security of transmission medium and difficult to steal. There is no doubt that optical network will be the mainstream network access technology in the future, especially the passive optical network technology. It avoids the shortcomings of the power supply unchanged, the equipment is complex, and the equipment input into the advanced active access technology. It significantly improves the stability and reliability of the network transmission system. This paper takes Henan FTTH cable as the research object, combined with the new standard of the existing broadcasting industry, summarizes the existing cable TV network scheme of FTTH, introduces the passive optical network (Passive Optical Network, PON) key technology parameters, and analyzes the advantages and disadvantages of technology. Then based on the current situation of Henan cable TV two-way network and the future development trend of radio and television network, in order to ensure the openness of the network, operable, manageable and value-added principles, the technical proposal of Fiber To The Home (FTTH) is proposed. The FTTH system is divided into A and B biplane architecture. A plane carrying digital TV broadcast channel and VOD channel on the original plane, B bearer data channel based on EPON, and to access capacity and network evolution are analyzed, finally carries on the analysis to the Anyang City District will hee FTTH project, and prospects of development of radio and television network FTTH prospects.
