For the implementation of real-time optical orthogonal frequency division multiplexing (O-OFDM) systems at data rates of 100 Gbit/s and beyond, quantization effects due to the limited resolutions of digital-to-analog converter (DAC) and analog-to-digital converter (ADC) play an important role. We study these effects both analytically and by simulation and present methods to mitigate their impact on signal quality and channel estimation.
