Design And Testing Of Ftth Optical Access Network In Changde

With the increasing demand of bandwidth, how to implement user broadband access has become to one of the urgent problems need to be solved. In each kind of services of broadband access that offers to telecom users, directly adopt FTTH optical access network is the most vitality scheme, because FTTH has solved how to provide data、voice and video traffic to users better, satisfied the needs of user for broadband traffics. On this condition, this paper present "Research and implement of Changde telecom FTTH Optical access network ".At the beginning, this paper analyses the present situation and development condition of domestic and international FTTH, illustrates realistic meaning and the necessariness of this research, present the major research content of this program.Then, this paper analyses the present situation of Changde telecom broadband IP access network, through analyzing for the demand of Changde telecom FTTH, explain feasibility and necessariness of Changde telecom FTTH optical access network, and discuss the steps how to implement the strategy of FTTH.Furthermore, study on the changde telecom FTTH architecture and key technologies in detail.emphasis on the network component and topology of FTTH, through analyzing and comparing for the various technologies of FTTH, determine to realize Changde telecom FTTH optical network with EPON technology, then study on the key technology、working principle and the system construction of EPON technology.According to Changde telecom FTTH system construction requirement, this paper adopt point to multi-point (P2MP) structure EPON technology for FTTH optical access network which from Changde telecom DeShan department to the Changde mansion of science and technology,and to the Liuye lake area. Analyses and calculate the network scale and network capacity of this FTTH optical access network, and design for network side OLT, user side ONU and passive optical distribution network ODN in detail.Finally, through tests certificate the correctness of solutions for the Changde telecom FTTH optical network.
