Abstract :
We demonstrate that the transmission of broadband radio over fibre signals at high frequencies using a multimode fibre link is contingent on the use of low-linewidth lasers. We describe the first subcarrier transmission of QPSK data signals through a 62.5 mum core-diameter graded-index multimode fibre links up to 5 km for the widest range of microwave frequencies ever reported (from 3 to 18 GHz).
