After completing the Iruña-Burutain section in 2016, ADI TECHNICAL SOLUTIONS is currently carrying out the deployment of optical fibre by means of micro-trenching from Burutain to Bera, and the Elizondo branch, for the Government of Navarre, in collaboration with the Sistem company.

ADI is using cutting-edge machinery for the construction of the micro-trench, which is more than 40 km in length, 8 cm in width, and 40 cm in depth.
