The operational heart of an OTDR lies in two physical phenomena: and Fresnel reflections . When the device injects a high-powered pulse of light into a fiber, it doesn't just travel in one direction. Minute imperfections in the glass cause a small portion of that light to scatter back toward the source. Additionally, any abrupt change in the material (such as a connector, a splice, or a physical break) causes a sudden, strong reflection known as a Fresnel reflection.
