The Influence of Rayleigh and Brillouin Backscattering on the Performance of a 10 Gb EPON System

Yang ZHOU, Qi-wu WU, Hao CHEN, Fang LI


In order to improve the performance of 10 Gb Ethernet passive optical network (EPON). This paper builds a single channel bi-directional 10Gb EPON simulation system on the VPI simulation platform. By changing the system parameters such as Brillouin Scattering, Rayleigh back-scattering and AmplitudeRF, observed and analyzed the waveform, spectrum, eye diagram and bit error rate of uplink optical line terminal (OLT) received signal. Experimental results show that both Rayleigh and Brillouin backscattering have an impact on the performance of the system, but the Brillouin scattering effect is more affected when the two effects are simultaneously existed. In addition, the effect of Brillouin backscattering can be reduced by phase modulation of the optical uplink carrier.
