The Application Of GPON Technology In Access Network Of CMT City Branch Company

With the fast developing of internet technology, the amount of internet users is larger and larger and the bandwidth requirements are higher and higher. Under the backgrounds,copper access technology can not meet surrent correspondence's development. And the competition in teltcommunication market is rough. So, how to improve the ACCESS NETWORK's operation efficiency is the primary problem to operactors. Nowdays application cost is reducing. The difficulty of practical construction and routine maintenanceis descending. What's more, perforaccess networkce index level is rising.According to these factors, fiber access technology takes the place of copper access technolog step by stey.In this thesis, firstly I introduce the general situation of ACCESS NETWORK technology's development. I sun up advantages and disadvantages of this technology. Then by using contrastive analysis I find why we need to use GPON technology to build ACCESS NETWORK at technical levels. Secondly, I expound operation prineiple of GPON system and a number of FTTx application scenarios. I stress GPON technology network structure,gordian technique and working sence which different FTTx can apply to. I also emphasize some problems and matters need attention about internet structure design and special construct of ACCESS NETWORK pratical application in Dalian, the general situation of AN in optical fiber reform, the variation of bandwidth requirements caused by AN technolog's upgrade and corresponding measure, the pros and cons of scenarro plans. Finally, through the design scheme using GPON technology of FTTH access scenes in the example of residential broadband access to the specific case studies in FTTH construction based on GPON is how to carry out the overall design through the preliminary investigation, the matters needing attention in the implementation process and implementation and final acceptance, validate the feasibility of GPON Technology in Dalian railway access network the construction of the. This paper will combine the experience of access networky aspects of GPON in practical application scenarios such as network selection, cable laying,construction cost is summarized, the future development direction of GPON network relative to other technical advantages, and finally through the actual case to provide a template for the practical application of GPON network.
