【 摘 要 】

In this letter, we demonstrate a technique for suppression of transients in output bursts of an erbium doped fiber amplifier (EDFA) in an optical burst network. To suppress the transients, the EDFA is forward-fed by non-fluctuating input utilizing power-modulated burst control packets channel. Using the technique, we obtained maximally 1.7-dB reduction in gain transient in EDFA output, and we transmitted 9.953 Gb/s data bursts and 2.488 Gb/s burst control packets stably.
