Extensive comparisons of optical fast-OFDM and conventional optical OFDM for local and access networks

This paper describes a performance comparison between a recently-proposed novel technique known as fast orthogonal frequency-division multiplexing and conventional orthogonal frequency-division multiplexing, over unamplified, intensity-modulated, and direct-detected directly-modulated laser-based optical signals. The paper examines key transceiver parameters, such as the maximum achievable transmission capacity and digital-to-analog/analog-to-digital converter (DAC/ADC) effects.
