چکیده مقاله:
In this paper first we try to analysis the behavior ofthe SOAs in the optical networks and then have proposed anumerical simple model to simulate the behavior of thesemiconductor optical amplifiers. After that by employing thismodel as inline amplifier for a DWDM optical system, we havesimulated the transmission of ۱۰ channels with bit rate ۱۰ Gb/sup to distance ۳۹۷۰ km with RZ-DPSK modulation format at ۲۰GHz channel spacing. On the other hand in order to amplify thesignal at the transmission link, we have used ۷۳.۵km relay spanconsist of ۶۳km single mode fiber (SMF), ۱۰.۵km dispersioncompensating fiber (DCF) and a SOA at the end. Our resultsshow that by optimizing the key parameters of the SOA such asthe bias current and the input power and furthermore by properplacement of the spans, we can transmit the signal with goodamplification and low noise power.
