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.

This paper presents a new design methodology for hybrid optical amplifiers operating simultaneously at Cand L-bands. Our configuration uses an Erbium Doped Fiber Amplifier (EDFA) operating as a booster to obtain optical gain over the C-band and a Distributed Raman Amplifier (DRA) to provide gain over the L-band and control the gain ripple. The amplifier performance was computed in terms of on-off gain and ripple, Optical Signal to Noise Ratio (OSNR), and Noise Figure (NF). Our results show on-off gain from 17 dB with ripple up to 2 dB over a 65 nm bandwidth. The OSNR was higher than 35 dB with NF lower than 4 dB at 120 km. Fiber links from 90 km up to 180 km have been analyzed.
