The direct buried installation of photovoltaic power plants has outstanding advantages, which can reduce the accident rate, improve the reliability of power supply, and facilitate the subsequent construction, operation, and maintenance.
Direct burial is a better choice, for all fiber cables are buried underground and no need for poles. So buried laying is suitable for fiber optic cable installation in cities and places with this need. The main disadvantage of buried cable laying is that it affects the underground construction a lot.

Direct buried cables Trench Design. a. Cables exiting from main trenches shall be installed in conduit or in lateral trenches. b. Lateral trenches shall be similar in construction and installation
In direct buried cable construction, the fiber optic cable is installed directly into the ground rather than in protective conduits. When fiber optic cable is installed through a conduit via air, the process is known as air-blown or cable-jetting construction.
One method for installing direct-buried cables is to lay them in a prepared trench from a moving vehicle which carries the reel of cable. a. When cables are installed in this manner caution should be exercised to make certain that the minimum bending radius is not exceeded when the cable is being taken from the reel. (Note: If the reel should

Cables exiting from main trenches shall be installed in conduit or in lateral trenches. b. Lateral trenches shall be similar in construction and installation to the main trench. a.
The direct burial of cables at PV power plants can be a cost-effective approach – ensuring that cabling is out of the worst weather conditions and cannot be damaged by maintenance crews or local critters. However, when the cables are not themselves fit-for-purpose, it can lead to their breaking down, potentially causing faults and fires.
GV: If the cable described in 2 PfG 2642/11.17 is intended to be directly buried, it must have a metallic layer as protection against the ingress of humidity. Of course, this metallic layer must be closed and tight. We have installed string-cables in underground duct-systems.
TÜV Rheinland has developed the standard 2PfG2642/11.17 for direct burial cables. Is this a draft? Guido Volberg, Head of Technical Competence Center PV Modules and Components, TÜV Rheinland: No, the document was released on October 31, 2018, as a final specification.
