Abstract
In this paper, we have applied an equivalent electrical circuit model of erbium-doped fiber amplifier (EDFA) including chirping effect to analyze the distortions in subcarrier multiplexing (SCM) systems. The model is simple and convenient for analyzing the distortions and performance of lightwave transmission systems using EDFAs, through the aid of a SPICE circuit simulator. The performance evaluation is shown of a 42-channel SCM EDFA system, including the composite second-order distortions (CSO), the allowable modulation index, and the limit on the number of channels.
