The miniature air-blown optical cable was first created by the Dutch NKF optical cable company. Because the utilization efficiency of the pipe hole has been greatly improved, it has been widely used in the international market. In residential renovation projects, some areas may require optical cables to cross squares or roads. In the case that the overhead method is not advocated, if the road is excavated to lay the pipeline, the amount of work will be relatively large. The laying method of the shallow-buried optical fiber cable is very simple. It only needs to use a cutting machine to dig a shallow groove on the road with a width of about 2cm. , the depth is about 10cm, and the backfill is implemented after placing the optical cable, and the routing connection can be quickly completed.
