Comparison of optical performance monitoring techniques using artificial neural networks

Optical performance monitoring in transparent fiber-optic networks using neural networks and asynchronous amplitude histograms

“…Conventional network performance monitoring and management in the electrical domain can no longer meet the requirements of next-generation dynamic heterogeneous optical networks [5][6][7][8]. In recent years, artificial neural networks (ANNs) have been applied for monitoring channel impairments and it has been shown that ANN is a powerful tool for the OPM [9][10][11][12][13][14][15][16][17][18]. Among these reports, the technique based on asynchronous amplitude histograms (AAHs) and ANNs, proposed by T. S. R. Shen and F. N. Khan, behaved simple and cost-effective [9,10].…”
