Effect of ADC on the Performance of Optical Fast-OFDM in MMF/SMF-based Links
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.
