Research And Implementati On Of FTTH Access Method In Remote Rural Areas Of Wuming District

Vigorously develop the rural informatization is an important means of promoting agricultural modernization,rural well-off,the specific requirements are "13th Five-Year" plan,but because of the situation in rural areas,village complex distance,population living scattered,so network is generally by telephone line or ADSL wireless transmission mode.With APON,BPON to the current development of E/GPON technology,the new technique is presented to the floor,is a microcosm of the development of China’s Internet users,and finally realize the process of fiber elongation,fiber to the home,this is FTTH.The realization of FTTH in rural areas is of great significance to the modernization of the countryside.In response to the national "broadband China" strategy,Guangxi launched the broadband Guangxi strategic action plan in 2014,providing specific requirements for the development of broadband services in Guangxi.Urban informatization has been promoted for many years,and has accumulated rich experience,but the construction cost of FTTH and the lack of construction experience in rural areas are the biggest difficulties for "broadband Guangxi".Wuming District of Nanning city is underdeveloped area,mountainous area,complex terrain,between the village and the village looks near,but often the mountain barrier,need a very large number of remote access to FTTH village.Because of long distance transmission attenuation time only by reducing the splitting ratio to enhance optical power to solve,in the face of more than 20KM in the incapable of action can only give up.Therefore,the study of long-distance FTTH access in rural areas is of great significance for implementing the broadband Guangxi strategy.This article firstly analyzes the MPCP protocol in EPON system the most important,in-depth understanding of the working principle and the communication process,and proposes a method of remote access,adding relay under the premise of FTTH access service realization of remote rural stability;secondly,remote mountainous villages remote access time FTTH decline is too large,on the basis of the hardware analysis,in-depth study of the working principle of FEC encoding,and encoding technology through improving light link budget,by improving the optical link budget to achieve stable network transmission,FTTH access.This paper studies the increase of rural FTTH network transmission distance and improve the stability of the FTTH network,which has a strong practical significance for the informatization construction in remote rural areas,to enrich the Wuming Telecom FTTH network construction experience,improve the advantages of telecommunications business in rural informatization,reduce the investment cost of enterprises,plays an important role in enhancing efficiency.In addition,the results of this study provide technical references and engineering demonstrations for other EPON based network remote access.
