WCDMA radio-over-fibre transmission experiment using singlemode VCSEL and multimode fibre

A high-performance singlemode VCSEL developed for analogue applications has been evaluated for use in a radio-over-fibre link for WCDMA in-building distributed antenna systems. The experiment showed penalty-free transmission over a wide range of input RF powers. The ACLR limited the downlink input RF power to less than -13dBm.
