Problems solved by technology

However, from the actual situation, for areas without reserved communication pipelines, the investment cost is relatively high and construction is difficult; for areas with reserved communication pipelines, 20%-30% of the pipelines have been blocked due to ground subsidence and other pipeline constructions. As a result, the optical fiber cannot pass through. It can be seen that the cost of networking with a single optical fiber communication system is relatively high
