本文分别研究了16、32和64信道的10 Gbps WDM系统中采用EDFA、拉曼和SOA放大器的情况，并在传输距离和色散的基础上比较了非线性和非线性情况下的性能。结果表明，当色散为2 ps/nm/km，通道数较少时，SOA能提供较好的结果，因为随着通道数的增加，交叉增益调制、交叉相位调制和四波混频会导致增益饱和问题。当色散从2 ps/nm/km增加到10 ps/nm/km时，EDFA的误码率和输出功率都比SOA好，但增益谱不均匀。我们还观察到，拉曼放大器提供了更好的结果，为L波段放大和增益平坦的问题，因为它可以大大减少光纤非线性的影响。
In this paper 10Gbps WDM systems at 16, 32 and 64 channels have been investigated with EDFA, RAMAN and SOA amplifiers individually and the performance has been compared on the basis of transmission distance and dispersion with and without nonlinearities. It is demonstrated that when the dispersion is 2ps/nm/km and the number of channels are less, then SOA provide better results because as we increases the number of channels, the gain saturation problem arises due to cross gain modulation, the cross phase modulation and four wave mixing. When dispersion is increased from 2 to 10ps/nm/km, EDFA provides better results than SOA in the term of BER and output power, but it shows non-uniform gain spectrum. We also observed that RAMAN amplifier provides better results for L band amplification and gain flatting issue because it can substantially reduce the impact of fiber nonlinearity.
