“…A total of 20 WDM channels is introduced at time t = 0 ms, of which 17 are removed (channels 1, 2, 3, 4, 5, 6,8,9,10,12,13,14,16,17,18,19 and 20) at time t = 1 ms and then readded at time t = 2 ms. Each curve has been advanced 250 µs, time corresponding to the propagation delay of 50 km of Raman fiber. Fig.…”

“…Nevertheless, the transient response of HAs has been treated experimentally in limited scenarios, without giving a rigorous analysis of the obtained results [7][8][9]. Besides, we have presented the first work, and the only one to date, of power transients in cascades of HAs [10] with a numerical simulation approach; moreover, we have given accurate explanations of the results and the influence of each amplifier in every presented hybrid configuration.…”

In this work the power transient control in cascades of Hybrid Amplifiers (HAs) is investigated. Two hybrid configurations are considered: a backward pumped DFRA preceding an EDFA and a forward pumped DFRA ahead of an EDFA. In both cases the EDFA in forward pumped. When 17 out of 20 channels are dropped/added, the steady state power excursions of the surviving channels were reduced from 4.21 dB and 6.25 dB to 0.01 dB and 0 dB, for a single HA under configurations "EDFA + backward DFRA" and "forward DFRA + EDFA", respectively. When a cascade of 12 HAs (1800 km) is studied, the steady state output power excursions were drastically mitigated from 8.66 dB to 0.07 dB and 0.60 dB, for the same hybrid configurations, respectively.
