Feed-forward control of transient gain dynamics of an EDFA for optical burst networks

Abstract

,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 a power-modulated burst control packet channel. Using the technique, we obtained a maximum 1.7 dB reduction in gain transient in the EDFA output, and we transmitted 9 953 Gbps data bursts and 2.488 Gbps burst control packets stably.
