The Design And Implementation For The Yinchuan Local DWDM Network In Ningxia Telecommunication Network

As the IP services in the fixed network and 3G services in the mobile network growing rapidly, the network bandwidth demands from the operators became higher and higher. How to improve the benefit cost ratio and network bendwidth in the current telecommunication system is the key problem, in order to cope with the growing of different kinds of services. The DWDM (Dense Wavelength Division Multiplexing) technology, as its native advantages, becomes the key technology to solve the problem. DWDM technology can extend the fiber optical networks transport capacity quickly, simply, economically and efficiently. It can fully meet the current demand for business growth. It carries the data such as electronic mail, video and multimedia, data and voice by the IP,ATM and SDH/SONET(Synchronous Digital Hierarchy/Synchronous Optical Network) in the fiber transportation layer. The DWDM technology also provides a good foundation for all optical transmission network in future, provides a preparation for the further development of transmission network and mobile 3G industry in NingXia telecommunication system.This paper gave you a detailed imformation for the design and implementation for the Yinchuan local network DWDM transmission network in Ningxia telecommunication network. It introduced the background, advantages, the theory of technology and the key technology about DWDM technology. In view of design, ascertainment of the network parameters, configuration for the ID and channel, the network protection,monitoring and Network Management System design were described thoroughly, and the effective solution to the network design was proposed. Combining of the reality of the transmission network of Yinchuan local network DWDM of Ningxia telecommunication and business needs analysis, from the system structure, network organization, modules configuration, service migration, the paper illustrates the whole process of the design and implementation. And later, through loading the traffic signal, it gives the network performance tests and checks the channel for the protection. The testing results validate the correction of the design.As technology principle, I mainly finished DWDM network design, implementation, test and the successful organization and service migration. The present network is stable and services are running perfectly. It reached the established objective. The construction of Yinchuan DWDM network greatly eases the problem of Yinchuan local network DWDM of Ningxia telecommunication, such as extremely small in capability, narrow bandwidth, lack of resources, CAPEX and OPEX. Vigorous support and guarantee for the rapid development of business and whole business operation of Lingwu and Ningdong Development Zone are provided。...
