Analisis Perbandingan Penggunaan Penguat Optik terhadap Pengaruh Four Wave Mixing pada Sistem Dense Wavelength Division Multiplexing

Abstract

Research and development of telecommunications technology continues to progress to meet human needs in communicating. Fiber optic communication system is one of the best technologies used for today's telecommunication needs. The Dense Wavelength Division Multiplexing (DWDM) system is a development of optical fiber communication system technology which has very significant advantages compared to previous technologies. However, the Dense Wavelength Division Multiplexing ((DWDM) system has a weakness that can affect system performance, namely the non-linearity effect. One of the non-linearity effects that occurs in Dense Wavelength Division Multiplexing (DWDM) systems is Four Wave Mixing (FWM). The effect of Four Wave Mixing is very influential with changes in optical power in Dense Wavelength Division Multiplexing (DWDM) systems so that optical amplifiers are needed such as Erbium Doped Fiber Amplifier (EDFA), Semiconductor Optical Amplifier (SOA) and Raman Amplifier.This thesis will discuss a comparative analysis of the use of optical amplifiers against the effect of Four Wave Mixing on Dense Wavelength Division Multiplexing (DWDM) systems.The test was carried out using software Optisystem 7.0 by analyzing the Q factor and BER values of each optical amplifier.This study used two schemes, namely scheme 1 is to change the input variable cable length 50 – 200 km and bitrate 10 Gbps, 40 Gbps, 100 Gbps. Scheme 2 used in this test is to change the transmitter power value from 0 – 4 dBm to improve the best simulation results for the first scheme. The results of this simulation indicate that the Erbium Doped Fiber Amplifier (EDFA) optical amplifier has the best performance of the other optical amplifiers when the effect of Four Wave Mixing occurs where the maximum Q Factor value is 6,43824 with a BER of 5,04x10-11 in the simulation test scheme 1 and the maximum Q Factor value is 6,71442 with a BER of 7,89x10-12 in simulation test scheme 2.
