Channel Power Control of Genetic-Nonlinear Algorithm Based on Impairment Aware in Optical Network

The physical-layer impairments may weaken the signal quality in optical transmission link. And the signal quality degradation may substantially dent the performance of optical communications. This paper, taking into account the physical-layer impairments in performance optimization, proposes genetic-nonlinear algorithm to adjust channel power and optimize OSNR (Optical Signal Noise Ratio). Simulation results confirm the validity of the controlling strategy with the better dynamic and stable performance for adjustment of transmission power at the device nodes.
