Blowing uses continuous airflow or water flow to suspend and push the cable forward through the duct. Pulling relies on mechanical traction applied via rope, winch, or pulling eye. It. Unlike direct-burial or aerial fiber, duct fiber is designed to navigate pre-installed underground or above-ground ducts—offering unmatched protection, flexibility, and scalability for long-haul and urban connectivity.
