N2 - This work presents an experimental study of the optimal peak-power pulse for testing telecommunications fibers. Using a Q-switched fiber laser at 1060 nm, we obtained 100-ns pulses at a 10-kHz repetition rate with an average power of 60 mW corresponding to a 60-W peak power. With these pulses, we generated up to fifth-order Stokes within the fiber, with wavelengths on the third window of telecommunications. We demonstrate that the power exceeding the optimum peak power does not increase the penetration length of OTDR systems because of the pump depletion. The shape of the Stokes-shifted pulses attained at the end of the test fiber is similar to the pulse shape from a Q-switched fiber laser, also showing the possibility to produce suitable peak powers and pulse shapes for OTDR applications at different wavelengths.
