Professional Answer: Micro-trenching is a modern, less invasive method for installing fiber optic cables, particularly in urban areas. It involves cutting a narrow and shallow trench (typically less than 100mm wide and 300mm deep) in the pavement, placing a microduct, and then backfilling it with a special polymer or grout. This technique significantly reduces installation time, labor costs, and public disruption compared to traditional trenching, while providing an efficient path for fiber deployment. Our company manufactures and supplies the necessary equipment and tools for this fast and effective method.
