Inspecting bends and supports, protecting open ends, verifying connectors, clearing the pathway and recording an approved integrity test can reveal damage or obstruction before valuable fiber enters the route. The same checks should be repeated after civil work, flooding, route changes or a failed blowing operation.<\/p>\n<p><!-- references-update-2026-09-22 --><\/p>\n<hr \/>\n<h2>References and official technical resources<\/h2>\n<p>These references support the standards boundary and pre-installation duct-integrity discussion.
