Detailed Steps for Installation and Laying of Direct Burial Fiber Optic Cable

Direct burial fiber optic cable, which refers to the optical fiber cable directly buried underground, involves a relatively complex and meticulous installation and laying process. Below are the detailed steps for its installation and laying:

Firstly, the burial depth must be determined. The direct burial fiber optic cable must maintain a certain distance from the ground to protect it from damage caused by ground tension and to prevent it from freezing. This depth is usually determined through comprehensive consideration of various factors such as soil conditions, climate conditions, and cable types.

Secondly, the cleaning and backfilling of the cable trench are crucial steps. Before laying the cable, the bottom of the trench should be flattened and free of debris such as gravel and hard soil chunks to ensure a smooth laying process. After the cable is laid, backfilling work needs to be carried out. Initially, a 30cm-thick layer of fine soil or sandy soil should be used as a protective layer. It is strictly prohibited to mix gravel, bricks, hard soil chunks, or other impurities into the protective layer. The protective layer should be gently flattened using manual methods.www.adsscable.cn

During the cable laying process, mechanical methods are mostly employed for outdoor construction. Mechanical laying involves the use of trucks or cable laying trolleys as traction tools. First, the cable reel is loaded onto the trolley on the truck using a crane or lifting forklift. Then, a commander inspects the preparation work and directs the laying process. During the laying, the motor vehicle should move forward slowly while personnel drag the cable out of the reel by hand, gently placing it next to the trench. After releasing a certain length of the cable, it should be manually placed into the trench.

In addition, for cables or wires laid in the same trench, they should be laid separately. If laid in the same trench as buried cables, cables should be laid first, followed by fiber optic cables, and they should be arranged parallelly at the bottom of the trench. If there are any bends or arches, efforts should be made to flatten them, but never use brute force methods such as stepping on them.www.adsscable.cn

Finally, after the fiber optic cable is laid, identification work should be carried out to facilitate subsequent maintenance and management. Meanwhile, the traction force applied during the laying of the cable should not exceed the maximum laying tension to ensure the safety and stability of the cable.

Throughout the entire installation and laying process, strict adherence to relevant operational norms and safety standards is necessary to ensure the safety of construction personnel and the quality of the cable. At the same time, attention should also be paid to environmental protection, minimizing the impact of construction on the surrounding environment.

Please note that the installation and laying of direct burial fiber optic cables is a highly technical task, typically performed by professional construction teams. If you need to install and lay direct burial fiber optic cables, it is recommended to contact a professional construction company or team.
