• We combine approaches of compensation and mitigation in addressing EDFA gain transients in dynamic networks. We see that for network reconfiguration times <1 μs, typical of packet switching, a transient suppressed EDFA (TS-EDFA) is able to suppress the majority of transients, but at longer timescales (t_R =10μs and 100μs), use of a digital packet receiver to actively compensate for residual transients, enables error free transmission not achieved with TS-EDFA alone. These results show that both the TS-EDFA and digital signal processing at the receiver are required to minimise the impact of gain transients over all dynamic networking timescales.
