Packet traffic will dominate the future optical networks. In this work we experimentally access the impact of
Raman amplification on 10 Gbit/s and 40 Gbit/s packet traffic performances. For a 10 Gbit/s packet traffic it was
observed a decreased of 21 % on the Q factor value for the system with EDFA amplification and 9 % for the
same system with Raman amplification, as the burst off period decreases from 0.2 ìs to 1.6ìs. For 40 Gbit/s
systems it was not observed degradation, resulting from the bit sequence length.
