摘要：

The gain tilt responsible for second-order distortion generated by EDFA's in AM TV-systems is shown to be fundamentally different from previous belief. The relevant gain-tilt should be measured under locked-inversion conditions. It increases with signal saturation and can be significant even at the peak of the saturated gain-curve. Values up to 0.6 dB/nm are measured-60 times higher than previously expected. By proper EDFA design, the distortion can be reduced to acceptable levels on the cost of output power.
