SI-POF Transmission with CAP Modulation and Split–Complex MLP Equalizer

Abstract:

In this study, we investigate the performance of split-complex multi-layer perceptron (SC-MLP) equalizer for a step index plastic optical fibre (SI-POF) communication link employing the carrierless amplitude and phase (CAP) modulation scheme. The SC-MLP equalizer is proposed to mitigate the effect of intersymbol interference (ISI) and nonlinearity in the system. It is demonstrated that the SC-MLP offers significantly superior bit error rate (BER) performance compared to the complex-valued transversal equalizer and the complex-valued Volterra equalizer in a highly non-linear SI-POF system. For example, for a 10 m SI-POF, a data rate of 15 Gbps is attainable at a BER of 10-3 with SC-MLP compared to 10 Gbps with the complex-valued transversal equalizer using CAP–64.
