    Based on a recently proposed novel technique known as optical fast orthogonal frequency-division multiplexing (FOFDM), which has half the bandwidth occupancy compared to single quadrature based conventional OFDM, investigations are undertaken into the impact of an analog-to-digital converter (ADC) involved in FOFDM signals over unamplified intensity-modulation and direct-detection (IM/DD) multimode fiber (MMF) and singlemode-fiber (SMF) based links. It is evaluated, for the first time, two important issues: 1) The impact of signal quantization and clipping effects for identification of a set of ADC parameters using various FOFDM single-dimensional modulation formats; 2) The FOFDM ADC parameters are compared with the corresponding ADC parameters of a conventional OFDM over both MMF and SMF links. It is shown that FOFDM and conventional OFDM over MMF/SMF links have similar optimum ADC parameters for a targeted BER of 10 -3.
