Abstract

In this paper, we have analysed a ring-based wavelength-division-multiplexing passive optical network (WDM-PON), which provides fiber-fault protection by using dual ring architecture as well as Rayleigh backscattering (RB) noise mitigation. For protection and restoration against fiber fault, the dual fiber ring is used. Here, we discuss and analyse the characteristics of the downstream signals using 10 Gb/s ON-OFF keying (OOK), 10 Gb/s dicode-coded NRZ. Moreover, we also investigate the upstream traffic using the 2.5Gb/s OOK generated by the reflective semiconductor optical amplifier-based optical network unit. The ring-based WDM-PON with dicode-coded NRZ gives improved bit error rate (BER), hence reach of PON can be increased.
