Abstract: | In order to reduce the cost for delivering the ever increasing broadband services, network providers need to simplify their
network architectures and have a better control of the bandwidth. In this article, we propose a simple and cost-effective
bandwidth scalable passive optical network (PON) based on orthogonal frequency division multiplexing (BSOFDM-PON). We report
performance analysis in terms of the signal-to-noise ratio (SNR), bit-error-rate (BER), and error vector magnitude (EVM) of
a PON system accommodating 32 optical network units (ONUs). Our simulations have successfully demonstrated that throughputs
of 35.5 and 53.2 Gbps can be achieved using 16 and 64 QAM, respectively, within a total distance ranging from 20 to 30 km.
It gives throughputs of 1.10 and 1.66 Gbps per ONU. |
