We have developed some low-cost predistortion circuits to compensate second-and 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 second-and 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 based on a new and original procedure that formalizes and suitably integrates in a sinergistic way modeling, design, and experimental activities.
