| In recent years, optical communication has become the world's hot spots, within the scope of the development domestic telecommunication market kept 10% growth rate. In the construction of new transmission network at the same time, make full use of the existing resources for now network modification and optimization, can save investment and can achieve the purpose of network building; Network optimization is becoming network construction of a new hotspot.Local optical transmission network construction should be divided into backbone layer, convergence layer and access layer, backbone layer fulfilling the node convergence layer between business scheduling, complete the integration of small particles business converge, access layer and finish all kinds of user access. This thesis mainly of shijiazhuang local optical transmission network status of hierarchical meticulous introduction, the current net running huawei transmission equipment structure and functions of the introduction and now nets problem of depth analysis.This paper first of SDH optical transmission network are introduced in this paper, on the basis of shijiazhuang mobile local optical transmission network network status, the main equipment characteristics and transmission core layer, convergence layer and the access layer problems is discussed and analyzed.Combining the transmission network optimization, puts forward the purpose and significance of shijiazhuang local optical transmission network optimization design ideas and optimized solutions to meet the mobile business demand for transmission network, and at the same time, improve equipment utilization, reduce the network operation costs.Finally, the network transmission of shijiazhuang local optimal enforcement expatiated, to optimize the existing problems in the implementation are analyzed and put forward the solutions, and the optimum effect from equipment utilization, network cost and network reliability improvement are illustrated. |
