The Generalized Droop Formula for Low Signal to Noise Ratio Optical Links

We present a theoretical model that fully supports the recently disclosed generalized droop formula (GDF) for calculating the signal-to-noise ratio (SNR) of constant-output power (COP) amplified coherent links operated at a very low SNR. For single-mode nonlinear COP links we compare the GDF-SNR to...
