Most distributed optical fiber sensors rely on commercially available telecom fibers, which are low-loss, inexpensive, and standardized. In the last few years, significant effort has been made to develop fibers optimized for specific sensing applications, with view of improving signal-to-noise ratio (SNR) or extending distance over (DOFS) operate. This tutorial reviews efforts by scientific community towards development enhanced backscattering backreflection a focus DOFS.
