Fiber optic sensing turns buried cables into thousands of virtual sensors capable of detecting temperature, strain, and other changes along their length. This technology enables identification of exposed sections of direct‑buried telecom cables by analyzing temperature variations that indicate risks such as erosion or soil displacement. Because it eliminates the need for physical inspections, fiber sensing reduces operational costs, improves safety, and provides continuous monitoring. It offers a proactive way to detect potential issues before they lead to service interruptions or cable damage.
