Abstract

We investigate the effects of Rayleigh backscattering in a RSOA-based WDM. The results show that the effects of Rayleigh-induced penalty on the gain of the RSOA and the lengths of drop fibers using MZI switching. In this paper, we propose and demonstrated a novel Rayleigh backscattering (RB) noise mitigation scheme based on MZI switching for wavelength division multiplexing. Reflective semiconductor optical amplifier (RSOA) are used in the WDM network for suppressing the mitigation and noise. With MZI switching, interference generated by carrier RB noise at low frequency region is eliminated successfully. Transmission performance for different parameters over 165 km universal fiber has been simulated and the optical-signal-to-Rayleigh-noise-ratio (OSRNR) can be reduced to 15 dB with MZI switching..
