摘要：

We have experimentally demonstrated the dynamic equalization of the nonuniform EDFA gain and WDM-network channel-power variations by using acoustooptic tunable filters (AOTF's) with active feedback, The AOTF's have multiple independent passbands and act as dynamic wavelength-dependent loss elements, After 1000 km transmission in a recirculating loop, the power differential is reduced from 20 dB to 1 dB for three 2.5-Gb/s WDM channels covering an 8-nm wavelength range, and a 10(-9) BER can be achieved for all channels.
