We experimentally demonstrate 63-GHz 1.244-Gb/s radio-on-fiber downlink data distribution using the remote optical frequency up-conversion technique. Sixty-three-gigahertz optical heterodyne local oscillator signals are cross-gain modulated by optical baseband signals inside a semiconductor optical amplifier. After photodetection, frequency up-converted signals at 63 GHz are generated. The bit-error-rate performance is investigated as a function of optical baseband signal power in a wide wavelength range.
