Abstract :
The power efficiency of a 2 Gbps OOK-based Impulse Radio-over-Fiber (RoF) system based on 5th-derivative Gaussian and Abraha´s pulse is studied in this paper, with the aim of optimizing the Mach-Zehnder Modulator (MZM) setup. The best peak-to-peak (p-p) voltage is computed for several fiber lengths up to 40 Km. It is shown that adapting the p-p voltage with distance, with a trade-off between MZM output power and linearity while respecting FCC spectral constraints, can improve the system performance.
