Abstract:
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. The feedback path includes a frequency shifter for shifting the frequency of the feedback signal to a feedback frequency different than the transmission frequency.

Claim (Index 18):
A system for transmitting a radio frequency (RF) signal over an optical fiber comprising:\n an RF signal source configured to produce an RF signal at a transmission frequency; a pre-distorter for pre-distorting the RF signal; an RF power amplifier; a first Radio over Fiber (RoF) link for converting the RF signal into an RF optical signal and transmitting the RF optical signal from the radio frequency (RF) signal source towards the RF power amplifier, the RoF link including:\n an optical transmitter, \n an optical fiber, and \n an optical receiver which converts the RF optical signal into an RF electrical signal; and \n a feedback path including an RF analog tap for coupling a portion of the RF electrical signal to a second RoF link for transmitting the RF electrical signal towards the pre-distorter, the RF analog tap being disposed between the optical receiver and the RF power amplifier; and wherein the feedback path further includes a frequency shifter configured to up-shift or down-shift a portion of an electrical RF signal at the transmission frequency depending on the transmission frequency, wherein the frequency shifter receives the portion of the RF electrical signal and outputs a frequency shifted RF signal, the frequency shifted RF signal being different than the transmission frequency.
