Problems solved by technology

However, these methods have technical defects to varying degrees. The main problem is that the optical device needs to be connected in series between the optical transmission equipment and the optical cable line. Once the optical device itself fails, it will cause the failure of the optical fiber communication transmission network.

In addition, when installing the automatic monitoring system for optical cable lines, it is necessary to stop the operation to complete, which will undoubtedly increase the blocking index of the optical fiber communication transmission network
