Quality of light path with ASE noise accumulation in nonlinear optical propagation using global performance metrics

In this paper, we have targeted our investigations to the inclusion in performance evaluation of light path on the effect of amplified spontaneous emission (ASE) noise accumulated in nonlinear optical propagation. Quality of light-path transmission feasibility has been reported by using a global performance metrics, called Q-factor, optical signal-to-noise ratio (OSNR), BER, extinction ratio and nonlinear frequency shift, which takes into account the interaction between the parameters aforementioned and returns a unique value corresponding to the performance metrics.
