What Are The Aerial Optical Cable Laying Requirements?

Aerial fiber optic cable can exist between buildings and buildings, between buildings and utility poles, and between utility poles and utility poles. The actual operation depends on the situation at that time. When there are electric poles between the buildings, steel wire ropes can be erected between the buildings and the electric poles, and the optical cables can be tied to the steel wire ropes; if there are no electric poles between the buildings, but the distance between the two buildings is about 50m, Optical cables can also be erected directly between buildings through steel cables, and the laying requirements are as follows:

1. When laying the aerial fiber optical cable in the flat environment in an aerial way, use the hook to hang it; when laying the optical cable in the mountain or steep slope, use the binding method to lay the optical cable. The optical cable joint should choose a straight pole position that is easy to maintain, and the reserved optical cable should be fixed on the pole with the reserved bracket.

2. The optical cable of the overhead pole road is required to make a U-shaped telescopic bend every 3-5 poles, and about 15m is reserved for every 1km.

3. Use galvanized steel pipes to protect the overhead (wall) optical cables leading up, and the nozzles of the pipes should be blocked with fireproof mud.

4. Aerial optical cables should hang optical cable warning signs every 4 bars or in special areas such as crossing roads, rivers, and bridges.

5. A three-prong protective tube should be added at the intersection of the empty suspension line and the power line for protection, and the extension of each end should not be less than 1m.

6. The pull wires of electric poles near the road should be covered with light sticks, and the length is 2m.

7. In order to prevent the induced current of the suspension wire from hurting people, each pole pull wire is required to be electrically connected to the suspension wire, and each pull wire position should be installed with a pull wire ground wire. The suspension wire is required to be directly connected with a lining ring and grounded directly at the terminal.

8. The overhead optical cable is usually 3m from the ground. When entering the building, it must pass through the U-shaped steel protective sleeve on the outer wall of the building, and then extend downward or upward. The aperture of the optical cable entrance is generally 5cm.
