Design of all-optical networks considering power consumption and four-wave mixing

This paper proposes a static lightpath establishment scheme considering power consumption of optical amplifiers and four-wave mixing (FWM) in all-optical networks. In all-optical networks, optical amplifiers consume much power to amplify a group of optical signals with different wavelengths. The FWM is one of the most important physical impairments to be resolved in all-optical networks because the FWM induces nonlinear inter-channel crosstalk and decays the performance of all-optical networks. The proposed scheme provides an ingenious route, wavelength, fiber selection strategy aiming to minimize the power consumption of optical amplifiers while suppressing the accumulation of the FWM crosstalk effect. Through numerical experiments, we show the effectiveness of the proposed scheme.
