OSSB-OFDM transmission performance using a dual electro absorption modulated laser in NG-PON context
Résumé
We report system simulation and experimental results on enhanced transmission distance over standard single mode fiber thanks to a novel dual modulation technique that generates a wideband optical single side band orthogonal frequency division multiplexing (OSSB-OFDM) signal using a low-cost, integrated, dual RF access electro-absorption modulated laser. We obtained in experimentation and by simulation a bit error rate (BER) lower than 10-3 for 11 Gb/s up to 200 km in an amplified point-to-point configuration for an optical single side band discrete multi-tone (OSSB-DMT) signal. We also experiment in simulation conventional OFDM at 25 Gb/s in point-to-multipoint architecture and we show that the transmission reach can be extended to 55 km for a BER at 10-3 thanks to the new technique we have developed and implemented.
