Design And Engineering Practice Of Lanzhou Tietong Telecom Access Network Based On GPON

As a kind of new-type Passive Optical broadband integrated access technology,GPON has a number of advantages,such as high-bandwidth, high-efficiency, wide-coverage and rich-user interfaces,and it has been seen by most of the telecom operators as the ideal technology to make the Access-Network-Service broadband and comprehensivized to be ture.Now Lanzhou Tietong Telecom is actively exploring and implementing the construction of access network based on GPON.Centring on the design and engineering practice of Lanzhou Tietong Telecom access network based on GPON,the thesis has analyzed the structure of GPON-Network,the characteristics of technology,the access mode.And then,in combination with the status of Lanzhou Tietong Telecom access network,the thesis proposes the GPON-based access network construction overall deployment scheme of Lanzhou Tietong Telecom,including the OLT room layout,and ONU installation manner,the principle of IP address and PON port planning,the attenuation of optical circuit,etc.Finally,the thesis proposed the application model of FTTx access network construction,based on the application scenarios of GPON technology.According to the status of optical users and business demands of difference users,the FTTx access network has been applied into newly builded FTTH access network construction of Lanzhou Tiejianliyuan Plot,and the network-hardware reform and construction of original ADSL access into FTTH access of Kangyiyuan Plot.Moreover,the business applicability of GPON technology has been verified by the data production of FTTH terminal device and the intercalate-test of IP site.The application of GPON technology in FTTH access network will certainly produce a better development opportunity for the traditional telecom business,will certainly attract more and more potential users,and will certainl produce more and more economic value.
