Branch Of China Unicom Zhangjiakou Ftth Network Planning And Reconstruction

China united network communication Co., LTD. In hebei branch, zhangjiakou branch membershipA complete fixed network and relatively perfect mobile network, solid fixed network business base and certain mobile business scale, a relatively complete all the business operation experience. Along with the national broadband speed strategy deepen ceaselessly, the fixed-line broadband access scope and bandwidth will increase to LTE, at the same time as the 3G, YiDongWang node on stage evolution cable nets needs more and more is also high, to satisfy all sorts of rapid development of business and three nets fusion steadily, reasonable and effective and appropriate leading local cable nets transformation in is very necessary. The local cable nets is a local transmission network is an important part of all kinds of business fastExpanding and good development prerequisite conditions, is a mobile business, broadband access comprehensive business continued good development key. Should be based on the transmission, IP, voice network structure, business development plan and the urban development planning ahead construction, through all levels of the interconnect form a reasonable structure and wide coverage and access flexible, maintenance convenience, safety and reliability of the cable nets, and meet the needs of business bearing. This thesis mainly research is zhangjiakou branch network planning and the 2010 FTTH reform Build. Mainly for improving the existing urban trunk cable network zhangjiakou city, in order to meet the new modeling Block bureau, big customers,3G base station fiber-optic access requirements. Cable network reconstruction should adhere to the "layered, partition construction, highlight key, appropriate leading development, resources optimizing both" principle, strengthen the distribution of optical business needs access analysis and prediction, we will focus on the access backbone layer fiber planning, key development, improve the user dense regions of big customer fiber-optic access network security. In principle of urban range coverage to achieve 100%, suburban overlapping coverage to 95 percent, basically have fiber to the building, optical fiber to the side of the road, the ability of the optical fiber to district; In the county city to be covered in the main streets and main customers; County should cover all the following cable nets township and main administrative villages, and soon to all administrative villages and gradually to natural village extensions. In the existing situation and market access conditions of comparative analysis, my company confirmed a city cable nets modification to transform FTTH primarily, by the FTTB transformation overall reconstruction scheme auxiliary.
