We experimentally investigate transient effects of our proposed single pump, dispersion-compensating Raman/EDFA hybrid amplifier recycling residual Raman pump in a cascaded EDF under the situation of multi-channel add/drop, and then demonstrate the use of a FBG based all-optical gain-clamping technique to efficiently suppress the output transients. The results show that the proposed hybrid amplifier has a significantly long transient response time of ~2 ms compared to the previous reported value of the conventional separate pump, Raman/EDFA hybrid amplifiers due to both the low-pumping regime operation of 14XX nm pumped EDFA section and the additional pump transit time through the 12.6 km long dispersion compensating fiber to reach the EDF. However, using a simple gain-clamping method we obtain an almost, transient-free operation.
