Abstract
The effect of environmental perturbations applied to long-haul submarine cables on the COTDR performance is shown for the first time. A simulative experiment employing perturbation-tracking compensation based on software processing reveals that we can compensate for SNR degradation caused by a random Doppler frequency shift in backscattering.
