The Applied Research Of DWDM Technology

Fujian Province is located in the southeast coast of China.With the development of various communication services, the business grew the network.The increasing bandwidth on the transmission system on the proposed demanded more. Recently the bandwidth requirements of Fujian Telecom Chinanet backbone, Fujian CN2 backbone network services are increasing.The bandwidth of long distance DWDM system has no sufficient redundancy to host new business channel. Therefore, long-haul DWDM systems in the province imminent expansion.In this case, participation in the provincial network of four WDM projects meet business needs. In this project, the author responsible for and participated in feasibility studies, equipment selection, network design, construction and engineering inspection and subsequent maintenance. The project uses FONST W1600 80×10G equipment, which is produced by advanced communications equipment manufacturers-FiberHome technologies company.The author designed the network topology to the mesh network topology, and completed standardization of the operation in the design and acceptance process. After the completion of works, it provided channels of data services to meet the needs of large particle channel and alternative access for existing WDM networks and SDH networks.The parties have been well received.
