WebAs we can see in the figure shown above that an optical time domain reflectometer contains a light source (mainly a laser) and a receiver along with a coupler or circulator. The coupler is connected with the fiber under test through a front panel connector. The laser produces a short and intense light beam. WebTime Domain Reflectometer starts its operation by sending impulse or step signals or energies. Then it observes the reflected energy or the signals subsequently. The discontinuity of impedance is measured and analyzed by the reflected pulses of energies as the amplitude, magnitude, and waveforms help in analyzing. devils lake gun showWeb5.2.3 Optical Frequency-Domain Reflectometry (OFDR) based distributed sensor.
