Abstract

We successfully demonstrated real-time 16 quadrature amplitude modulation (QAM) encoded 11.52 Gb/s optical orthogonal frequency division multiplexing (OFDM) transceiver and experimentally investigated its optical transmission performances for OFDMA-PON systems. Considering practical deployment of OFDMA-PON, we decided to design and implement the 128 fast Fourier transform (FFT) in our OFDM baseband transceiver. So, the number of available OFDM subcarrier was 63, which would be sufficient for accommodating 32 subscribers. We successfully achieved BER below 1×10−3 and also observed negligible power penalty over SMF 20km.
