The cascade EDFAs have to be used if the distance between nodes is extremely long in WDM network. However, the gain spectrum of normal EDFA is not flat. This will become much serious as the number of cascade EDFAs is huge. The gain spectrum is studied both theoretically and experimentally in this paper. A special designed FP filter is used to compensate the gain difference after cascade EDFAs used.
