This research investigates the deployment of low-complexity neural networks to mitigate performance degradation in long-haul coherent transmission systems that utilize cascaded Semiconductor Optical Amplifiers (SOAs). SOAs, while cost-effective and compact, introduce signal distortions due to gain saturation and finite carrier lifetime. This study demonstrates that NNs can effectively compensate for these impairments, significantly reducing Bit Error Rate (BER) and paving the way for more robust and efficient optical networks, especially in the low-dispersion O-band.

Case Study: FPGA-Enabled Real-time Equalization
This research highlights the feasibility of implementing low-complexity neural networks (MLPs) on Field-Programmable Gate Arrays (FPGAs) for real-time equalization. Previous studies demonstrated similar architectures, such as a two-layer perceptron with 33 and 14 neurons for 50 Gb/s PON, and a two-layer 1D CNN for 20 GBaud IM/DD PON. The proposed 33-128 neuron MLP model, and its variants (17-64, 33-256), are intentionally designed to remain close to these FPGA-oriented implementations, ensuring that the benefits of order-of-magnitude BER reduction can be realized in practical, high-speed optical communication systems without significant hardware overhead.
