We demonstrated the analogue transmission of a 622 Mbps millimeter-wave signal over optical fiber for a broadband fixed wireless access system. The transferred RF signal format was based on four multi-carriers in a 37 GHz band with a 64 QAM modulation. The experiments showed that we can successfully transfer a 622 Mbps millimeter-wave signal over a 10 km fiber with less than 5 dB power penalty for a downlink and less than 4 dB CNR penalty for an uplink.
