Today’s networks are more demanding than ever—always on, always reliable, and no downtime regardless of application or environment. Instead of responding to issues once they occur, owners and operators are looking for ways to proactively manage their infrastructure. Imagine being able to detect small acoustic, temperature, and/or strain changes anywhere along an optical cable in an outside-plant environment, continuously, accurately, and in real-time. Or the ability to detect various environmental events at distances from ones to tens of kilometers away, with large numbers of distributed virtual sensors along the path. All this is possible by using optical fiber as an intrinsic sensing medium.
