Abstract
Amplifiers (EDFA) on Optical Burst Switching (OBS) networks, operating at the typical bit rate for current
passive optical networks ( PON), 2.5 Gb/s. A packet with 216 – 1 pseudo random binary sequence (PRBS) with
an idle length equal to 50000 was studied under different pumping powers of the EDFA. To assess the impact of
transients on the system performance, the gain excursion and signal to noise ratio (SNR) were measure and eye
diagrams were analyzed. It was observed that as the pump power increases (driving current from 0.80 A to
1.50 A, the SNR and the extinction ratio decrease 3.59 dB and 2.33 dB respectively, while the gain excursion
increases 8.4 dB.
