Our Professional Answer: Trenchless technology, such as Horizontal Directional Drilling (HDD), offers significant advantages for installing backbone cables, especially in urban or sensitive environments. These benefits include:

• Minimal Surface Disruption: It avoids large-scale excavation, keeping roads, pavements, and landscapes largely intact.

• Reduced Cost and Time: By eliminating the need for extensive digging and surface restoration, trenchless methods significantly reduce project timelines and labor costs.

• Environmental Friendliness: With less excavation, there is a smaller carbon footprint and less impact on local ecosystems.

• Overcoming Obstacles: This method is ideal for laying cables under existing infrastructure, such as roads, rivers, or railways, without disruption.
