1. When choosing a corrugated pipe routing router, the corrugated pipe should be installed as far as possible in the area that everyone must not touch, and it does not need to be set in a position that is not conducive to the appearance. Generally, a corrugated pipe with a diameter of not less than 25mm should be selected.

2. Define the installation location of the passing box, and set the passing box at the household registration place of the housing module and the intersection of the horizontal and vertical pipes; when the length of the parallel line of the horizontal corrugated pipe exceeds 30m or the length of the section exceeds 15m and there are 2 When the angle is above 90°, a pass-through box should be set.

3. Install the pipe hoop and fix the metal corrugated pipe. At the corner of the router or the convex and concave parts of the building, the corrugated pipe needs to maintain a certain arc shape and then install and fix it to ensure the bending radius of the leather cable and facilitate the penetration of the cable. put.

4. Thread the sheathed optical cable in the corrugated pipe (the pipe threader can be used when threading and routing the sheathed optical cable in the corrugated pipe with a long distance).

5. When passing through two parallel line passing boxes continuously or according to the direction of the passing box and pulling the optical fiber cable at the entry point, the optical fiber cable should be pulled out of the passing box and put back in again.

6. The length of the leather cable in the passing box should not be kept long, it only needs to reach the bending radius of the leather cable. After the leather cable is disconnected, make sure that the leather cable in the passing box is not squeezed, especially pay attention to the leather cable at the corner of the passing box.

7. Close the cover of each pass box.
