(With the rapid development of the economy, people's demand for communication is getting stronger and stronger, and the requirements for communication quality are getting higher and higher. At the same time, the competition in the market is also becoming increasingly fierce. Therefore, only by continuously improving the quality of network operation and maintenance can provide users with High-quality service can better win the market. This makes the maintenance task of optical cable lines heavier and heavier, and there are more and more problems involved in line cutover and fault repair. If the circuit is cut by the traditional method, the optical cable will be interrupted for 4-6 hours on average. During this period, a large amount of data and information will be interrupted. On the one hand, it will cause huge economic losses, and on the other hand, it will also seriously affect the "fiber availability" "circuit Availability” and other indicators. In order to adapt to the current situation, keep up with the new knowledge and development trend of communication technology, and improve the core competitiveness of enterprises, we have summed up a new set of "optical cable tape business cutover" methods through long-term practice, from the two aspects of technology and process. The original cutover process is reformed to greatly reduce the average time of service interruption in the cutover of optical cable lines, thereby ensuring the improvement of the "circuit availability" index. 2. Definition of optical cable tape business cutover: Optical cable line cutover method that uses existing telecommunication resources to avoid long-term interruption of in-use services and perform instantaneous interruption (within five minutes) through various scheduling methods. 3. The meaning of implementing optical cable tape business cutover 1. Impact on business income The principle that everyone follows in the optical cable cutover is to try to dispatch the system in the optical cable to be cut to other routes as much as possible, and the system cannot call out The optical cable can only be cut off when the service is stopped. Therefore, since the average cutover time is 4-6 hours, and the average number of planned cutovers per year is 330 to 380 times, the direct economic loss will be at least nearly 10 billion yuan (theoretical value). However, if the service cutover is implemented and the power-off time of each circuit is controlled within 5 minutes, the direct economic loss will be reduced by 72 times and controlled at about 100 million yuan.)
