The Research And Application Of Tianjin Unicom Broadband Speed Upgrade Scheme

The current user access network is a bottleneck for Tianjin Unicom’s broadband network development. In this article, the authors discuss and analyze the existing problems of the current access network of Tianjin Unicom based on site surveys and collected data and give some ideas on the broadband upgrade project. The tradeoffs of different upgrading plan are also compared and discussed. Based on the comparison and analysis results, the authors suggest the future broadband network should be upgraded using PON as the core. It is also suggested that a hybrid of FTTH and ADSL should be the major access network. The provided information is expected to be useful for the similar network design in the future.The current status of local networkin Tianjin Unicom broadband through the building over the past decade, have been installed in each room broadband access equipment; has been achieved on the local network in Tianjin full coverage of broadband services in Tianjin’s largest carrier. For different customers and access the situation. Medium on the basis of the theoretical analysis of the local access network problems and improvements, and building programs to plan, In Tianjin, China Unicom supporting the building of the local access network, particularly within the region in Baodi the guidelines now being followed in the side of the layout of the network structure, while the mi-nor alterations, and for new buildings, residential and other areas the use of a new access mode optical fiber end, giving the user a one-time cloth into place. Baodi home district in the initial construction of the new river port1000using the scale, the rate of the test results based on feed-back, all commitments to achieve the design value at different rates, users agreed.The practical application of program verification, validation programs developed with the actual reference and maneuverability. After a field survey of this thesis, Tianjin Unicom collection the actual situation of the access network, fiber optic network construction planning ideas, especially the demand for FTTH access network. We need analysis of the merits of networking review.
