An aspect of the disclosure provides a system for transmitting a radio frequency (RF) signal from a source to a destination. Such a system includes an RF signal source configured to produce an RF signal at a transmission frequency. The system further includes an optical transmission path for optically transmitting the RF signal towards the destination. The system also includes a feedback path for transmitting a feedback signal received proximate the destination towards the RF signal source.
