"WebRayleigh backscatter is used primarily for distributed acoustic applications. Acoustic signals or sound waves that impact the fiber cause small changes in the refractive index. These changes can be detected with Rayleigh backscatter when using a coherent optical time-domain reflectometer (COTDR). Standard singlemode optical fiber is typically used.
