Abstract—The paper experimentally demonstrated the optical frequency quadrupling microwave signal gen-
eration, a 4 GHz radio frequency (RF) signals up-conversion to 16 GHz in a radio over fiber (ROF) link, using
twice optical carrier suppression modulation. The RF signal was mixed with 1.25 Gbps NRZ-OOK data firstly
and then modulated by two cascaded single-electrode optical intensity modulators. The obtained 1.25Gbps/16
GHz ROF signal was transmitted and characterized in the optical fiber link. At BER of 10^–9, low power penalty
of 1.0 and 1.4 dB were obtained over a fiber link with a transmission distance of 25 and 50km.
