We have investigated gain flattening of EDFA systems with or without a gain equalizer for WDM long-haul transmission using are-circulating EDFA loop. Without a gain equalizer, gain variation as small as 2.9 ㏈ was achieved over the 10-㎚ band of a 100 cascaded EDFA system by the inversion principle. With a gain equalizer based on all-fiber acousto-optic tunable filters, two different configurations of EDFAs were tested. For a single- stage EDFA scheme, the 21-㎚ band has shown 3.8 ㏈ of gain variation at 17.4 ~ 20.3 ㏈ of OSNRs after the 100th stage of EDFAs. For a dual-stage EDFA scheme, a wider bandwidth of 34 ㎚ has shown 3.6-㏈ variation after 40 cascaded EDFAs.
