【摘要】 在接入网络飞速发展的过程中,由于传统电信业务、商业户和市场的需要,固网经营商之间的竞争明显加剧；固网经营商与传统固网经营商也在积极拓展宽带业务。经营商纷纷开发各种多媒体业务和增值业务,但是由此也带来了用户带宽需求的大幅增长。宽带业务在发展过程中,是要求宽带接入网在速率、内容、质量及安全等方面都有比较强的延伸能力和把控能力。由于通信接入网在转型的方面部分策略正在发生变化,通信运营商将工程接入从铜线接入网转向了光接入网,并且正在通过前期分阶段地实现通信运营商的宽带接入网逐步光纤化,最终实现光纤到家庭(Fiber To The Home, FTTH)。无源光网络(Passive Optical Network, PON),它是一点到多点的光纤在宽带接入网上的技术,它主要是由用户方面的光网络单元(ONU)、机房主干方面的光线路终端(OLT)以及整个通信接入网中的光分配网络(ODN)组成。而“无源”是指在整个通信接入网中的光分配网络ODN中没有任何有电源接入的电器及任何电源,全部由分光器(Splitter)等无电源接入的器件组成。本文着重分析了FTTx模式的多种实现方式,从90年代开始比较流行的ADSL开始,到PON+PBX组网方案、PON+无线AP组网方案、光纤收发器网线接入、PON+交换机、PON接入+FTTB,再到最终的PON接入+FTTH等一系列组网方式的详细接入方案。另外,通过上述的详细分析,得出比较符合实际的工程建设方案。另外,本文列举出一个本人工作中负责的江西省萍乡市莲花县明景花园小区宽带接入工程实例,通过分析明景花园小区宽带接入需求后,本人做出详细实施方案,并按照公司工程相关规定对该小区进行施工,施工过程中实时监控施工质量及施工安全,最后对该小区进行最终的验收,以确保能够满足该小区整体宽带的需求。本文通过工程实例对FTTH和FTTB接入方式做出最终的最优方案确定,另外通过GPON和EPON的详细技术参数比较得出最优化结论。更多还原

【Abstract】 In the process of rapid development of access network, due to the traditional telecom business, commercial users and market needing, fixed network operators between competition significantly increased; solid network operator and the traditional fixed network operators are actively expanding broadband business. Operators have developed a variety of multimedia services and value-added services, but this also brings the user bandwidth demand for substantial growth.Network services in the development process, network requires in terms of rate, content, quality and safety are relatively strong extension ability and the ability to control. Due to communication access network in the transformation of part of the strategy is changing, the telecom operators will access project from copper line network to the optical network, and it is through the early stages to achieve progressive of optical fiber communication operators of broadband access network and eventually to realize the fiber to the home (fiber to the home, FTTH).Passive optical network (PON), it is point to multi point optical fiber in the network technology, which is mainly composed by the user in terms of the optical network unit (ONU), room main optical line terminal (OLT) and the communication signal in the optical distribution network (ODN). "Passive" is refers to, without any power electrical and any power, all the optical splitter device etc. without access to power the device components in the communication access network, optical distribution network of ODN.This paper focuses on the analysis of the FTTx mode multiple implementations. Starting from the 1990s began to popular ADSL, to PON+PBX networking scheme, PON+ wireless AP network scheme, optical fiber transceiver cable access, switch PON+, PON+FTTB, again to final PON+FTTH a network with access scheme. In addition, through the detailed analysis of the above, it is more consistent with the actual project construction program. Also listed in this paper I work in responsible for the Jiangxi Province Pingxiang Lianhua County mingjinghuayuan residential network access project examples, through mingjinghuayuan residential network access demand analysis, I make a detailed implementation plan, and in accordance with the relevant provisions of the engineering company of the small area of construction, in the construction process of real-time monitoring of the construction quality and construction safety. Finally, the district were final acceptance, to ensure to meeting the needing of the whole area. In this paper, through the engineering example of FTTH and FTTB access mode to make the final optimal scheme to determine, also through the detailed technical parameters of GPON and EPON comparison optimization conclusion.更多还原
