Abstract
In this paper, we investigate experimentally the impact of optical amplifiers, namely Erbium Doped Fiber
Amplifers (EDFA) on Optical Burst Switching (OBS) networks, operating at 2.5 Gb/s (typical bit rate for current
passive optical networks - PON). Bursts with 212-1 and 216-1 pseudo random binary sequence (PRBS) were
studied, with different idle times (from 2ìs to 80 ìs). The use of traffic with variable idle time was assessed in
order to evaluate the effect on the burst initial amplitude. We also analyzed the performance of the packet based system by measuring the Q factor at the receiver and concluded that the performance is not affected by the type
of traffic (variable or fixed idle times).
