Analog Laser Predistortion for Multiservice Radio-Over-Fiber Systems

  title={Analog Laser Predistortion for Multiservice Radio-Over-Fiber Systems},
  author={Luca Roselli and V. Borgioni and F. Zepparelli and Franca Ambrosi and M. Comez and Pier Faccin and Andrea Casini},
We have developed some low-cost predistortion circuits to compensate secondand third-order laser distortions in multiservice radio-over-fiber industrial systems. Depending on the predistorter configuration implemented, average reductions of 10–15 dB and of 8–10 dB have been observed in the laser secondand third-order distortions, respectively, within the cellular bands relevant to the European TETRA, GSM, and DCS standards. In particular, the development of the prototypes here illustrated is… CONTINUE READING
