A full-duplex millimetre-wave fibre optic system based on a highspeed elect
roabsorption transceiver (EAT) is proposed. Full-duplex fibre optic transmi
ssion of broadband (155.52 Mbit/s) 60GHz-band millimetrewave signals is exp
erimentally demonstrated. Excellent transmission quality (BER < 10(-9)) is
achieved for uplink and downlink transmission, simultaneously.
