In this work, we focused on the use of Distributed Fiber Optic Sensors (DFOS) based on Stimulated Brillouin Scattering (SBS) technology for monitoring water pipeline networks. In this context, the implementation of optic fiber sensors within the structural elements is particularly useful in. The case studies of four different fiber-optic sensors are presented in this chapter. The first case represents a novel method for measuring the absolute position based on the white-light channeled spectrum. With the invention of the laser in 1960's, a great interest in optical systems for data communications began. Laser systems could send a much larger amount of data than microwave, and other electrical systems. Glass fibers. Water Loss (WL) is a global issue. In Italy, for instance, WL reached 36.
