Abstract :
A new millimetre-wave over fibre architecture is proposed and demonstrated using remote cancellation of phase and frequency fluctuations of two-laser heterodyne. A 36 GHz millimetre-wave carrier is optically delivered with -85 dBc/Hz noise level at 10 kHz offset. The system is used to demonstrate transmission of a 68 Mbit/s BPSK modulated 36 GHz signal through 25 km standard single-mode fibre.
