EDFA transient control based on envelope detection for optical burst switched networks

We propose and demonstrate a simple technique to control rapid erbium-doped fiber amplifier (EDFA) transients in optical burst switched networks. We demonstrate a 6-dB transient reduction in a 10-Gb/s 80-km-long wavelength-division-multiplexing system with three EDFAs. We show through simulation that the technique can be used at the first EDFA in links of as many as ten EDFAs to control transients to within 2 dB.
