Optical Time-domain Reflectometers – OTDR, operation principle
Optical time-domain reflectometers inspect fiber-optic links, measuring losses and reflections from faulty connections or splices.
The FOA Reference For Fiber Optics
The Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults.
Choosing the Right Optical Time Domain Reflectometer (OTDR)
In general, fiber should be tested using the same wavelength that is used for transmission. Testing at a single wavelength will only allow fault location. Testing at dual wavelengths is recommended during

OTDR Optical Time Domain Reflectometer 80-100km | Fibertronics, Inc.
The optical time domain reflectometer is used to measure fiber length, total insertion-loss, and overall optical attenuation within a circuit.
WHITE PAPER: Understanding Optical Time Domain
An OTDR injects a short light pulse into a fiber and routinely measures reflected light from Rayleigh back scatter (dB/km) and/or Fresnel reflections (dB) that occurs when the light traverses along the length
Optical time-domain reflectometer
The scattered or reflected light that is gathered back is used to characterize the optical fiber. The strength of the return pulses is measured and integrated as a function of time, and plotted as a
