What are the most common and effective methods for installing underground fiber optic cables?

2025-08-14

The choice of installation method depends on the project's specific conditions, including terrain, urban density, and budget. The most common methods are:

  • Micro-trenching: This method involves cutting a narrow, shallow trench (typically 1-2 inches wide and 12-24 inches deep) in the road or pavement, laying the cable or micro-duct, and then sealing the trench. It is a fast, cost-effective, and minimally disruptive method ideal for urban areas with existing hard surfaces.

  • Horizontal Directional Drilling (HDD): This trenchless method uses a steerable drill to create a bore path under obstacles such as roads, rivers, or existing utilities. It is a preferred method for complex projects or environments where surface disruption must be avoided.

  • Plowing/Direct Burial: Using a vibratory plow, this method quickly buries the cable directly into the ground without the need for a pre-dug trench. It is highly efficient for rural or open areas with soft soil.

Our comprehensive range of equipment, including hydraulic cable pullers and cable laying equipment, is designed to support all these methods, ensuring efficient and safe installation regardless of the terrain.
