Optical Time Domain Reflectometry

Measurement of the elapsed time and intensity of light reflected on optical fibre using an optical time domain reflectometer. The reflectometer can compute the distance to problems on the fibre such as attenuation and breaks, making it a useful tool in optical network trouble-shooting.
