Abstract :
A high capacity millimetre-wave fibre-radio system with an elegant return path has been demonstrated for the first time using a number of novel techniques. A 60 GHz carrier signal was generated using a master/slave DFB laser configuration and a remote upconversion scheme was used to provide a fully transparent link for the data signal (120Mb/s QPSK and 20 FM TV channels). Furthermore, an electroabsorption modulator was used as a full duplex transceiver to provide an attractive strategy for the return path.
