The OTDR takes advantage of the scattering of light in optic fiber to make measurements. This includes a constant low level of backscatter created by the fiber called Rayleigh backscattering and a high-reflection peak at the connection point called Fresnel reflection.
Using these two methods, the OTDR can detect a range of physical events along the length of a link. These include connectors, splices and any other discontinuity that doesn’t totally break the fiber.

How to Use OTDR Testing to Troubleshoot Fiber Optic Cable Installations?
OTDR testing is a useful tool for troubleshooting fiber optic cable installations and certifying new ones. It can verify splice loss, measure length and find faults such as breaks.
An OTDR uses a high power laser light pulse to measure backscattered light in the fiber and reflected light from connectors and splices. It then displays the return signal as a trace or signature from the measurement of the fiber.
