| چکیده | ||
| In this paper first we try to analysis the behavior of the SOAs in the optical networks and then have proposed a numerical simple model to simulate the behavior of the semiconductor optical amplifiers. After that by employing this model as inline amplifier for a DWDM optical system, we have simulated the transmission of 10 channels with bit rate 10 Gb/s up to distance 3970 km with RZ-DPSK modulation format at 20 GHz channel spacing. On the other hand in order to amplify the signal at the transmission link, we have used 73.5km relay span consist of 63km single mode fiber (SMF), 10.5km dispersion compensating fiber (DCF) and a SOA at the end. Our results show that by optimizing the key parameters of the SOA such as the bias current and the input power and furthermore by proper placement of the spans, we can transmit the signal with good amplification and low noise power. | ||
