Experimental implementations of continuous optical time domain Fourier transformation based on time lenses and optical orthogonal frequency-division multiplexing (OFDM) system are carried out. Such a system is verified through 100-km transmission of 10-Gb/s non-return-to-zero (NRZ) intensity-modulated direct-detection (IM-DD) without any dispersion compensation. The system's bit error rate (BER) and power penalty are 10<sup>-12</sup> and 4 dBm, respectively.
