| With the continuous development of power grids, communication networks have also expanded the scale, and as a means of communication, the optical fiber communication technology has become one of the main pillars of the modern communication. The modern telecommunication network plays an important role in the world of new technologies, which is an important symbol of the revolution and one of the main transmission tools in the future information society. The construction of the optical ring network of Jinchang power company has begun to take shape. As the development of the business needs of the communications industry, a great deal of real-time information and office automation information has to be transmitted, and the quality of the communication, the reliability of the channel needs more stringent requirements. For its high quality, large capacity and stability, high reliability, the optical fiber communication network becomes the best choice. Based on the construction and operation application of the synchronous digital hierarchy(SDH) fiber-optic network of Jinchang power company in recent years, the key issues,such as the existing problems of the fiber optic ring network, the network topology, the circuit configuration and the rehabilitation project, etc., were discussed and studied seriously. It provides a feasible design to the construction of the optical communication ring network of Jinchang power company in the future. |
