Abstract

Analytical expressions of transient phenomena in discrete fiber Raman amplifiers (FRAs) are presented in this paper. It is found that the recovery time in gain-saturated backward-pumped FRAs equals to the round-trip time of optical wave in the FRA, and is typically in the order of 10-1 ms. The power excursion amplitude and recovery time will increase dramatically in cascaded FRAs, leading to severe system performance degradation. Characteristics of transience in cascaded and gain-clamped FRAs and some design guidelines are also discussed based on these analytical expressions.
