Project Design Of FTTB+LAN

The requirement of deploying the network in broadband is increasingly prominent with the development of Internet. How to solve the problem of the'Last mile'has become unable to evade for telecommunication companies. The research associated with the problem promoted the development of the access technique of broadband. There are several means for the broadband accessing techniques, the telecommunication companies are puzzled by a difficult subject that adopts which technique to suit the network access. The study of the application of the broadband access technology has been the difficult and hot subjects in the research in the theory and practice.Based on introducing the various techniques for the broadband accessing in this paper, the author centered on studying and discussing the concrete technique and the realizing process of FTTB+LAN, and analyzing the engineering design of the system as well as the acceptance of standard for the relative performances. The following part is the main introduction of various sections in the paper.First of all, the general broadband accessing techniques such as ADSL, VDSL, FTTX+LAN, HomePNA, HFC, LMDS etc in our country were introduced in sequence, the patterns of broadband access of the various telecommunication companies in our province were described. Then, the technique of FTTB+LAN was discussed in detail, it is a broadband access of the technique based on Ethernet, a genuine broadband technique, and it is also the pattern of the broadband access which is strongly recommend and fiercely competed by the telecommunication branches and the IP providers. FTTB adopts the access of DDN leased line, it is convenient to install FTTB, the terminal of the client only to install a network card to the computer, the user can deploy the network at high speed for 24 hours. The utilization ratio of the broadband is very high, the cost of investigation is very low; It is convenient to upgrade the network, and the current network investigation is protected in maximum limit; As the broadband of the output port is sharing, the utilized broadband of the user is limited by the number of concurrent users; the number of the accessing pair of users is relative much more.The network of FTTB+LAN mainly consists of the optical transmitting lines,...
