4. What are the two major pain points of China optical cable trunk line?

1. shortage of optical cable resources: At present, the demand for optical cable trunk communication in China is increasing, but the cost and time for laying optical cables are very high, which leads to insufficient supply of optical cable resources and is difficult to meet the needs of users. In addition, due to the lag of optical cable network construction in some areas, it will also lead to uneven distribution of optical cable resources.

2. Difficult maintenance of optical cable: The maintenance of optical cable trunk requires a lot of manpower, material resources and financial resources. Moreover, the route of optical cable is changeable and the environment is complex. In addition, optical fiber and other equipment are easily damaged. Once the optical cable breaks down, it is difficult to repair, and the influence may be very wide, which will lead to the decline of communication service quality and even great losses.
