Abstract

The Dense Wavelength Division Multiplexing (DWDM) system can be used to increase bandwidth and bit rate on fiber optic communications. But on long-distance transmission, DWDM systems will experience signal degradation such as attenuation and dispersion that can worsen the system performance. Erbium Doped Fiber Amplifier (EDFA) can be used to improve system performance by strengthening the power of the transmitted signal. Signal degradation caused by dispersion can be overcome by using Dispersion Compensating Fiber (DCF) fiber type. In this research, DWDM link design is designed using OptiSystem 15. The DWDM design uses 32 channels, 200 GHz channel spacing, and 40 Gbps bit rate per channel. The link length used is 180 km which consists of Single Mode Fiber (SMF) along 150 km and DCF as long as 30 km using EDFA amplifier. The experiment was conducted with variation of power on CW laser equal to -8, -6, -4, -2, 0, 2, 4, 6, and 8 dBm.The result of system performance on BER parameter has a minimum BER value of 4,327 x 10-249 at CW Laser power of 8 dBm, while BER maximum is 2,207 x 10-07 at CW Laser power equal to -8 dBm. The Q-Factor parameter has a maximum Q-Factor value of 33.678 at 8 dBm Laser CW power, while for minimum QFactor has 5.015 at CW Laser power -8 dBm. The Received Power parameter has a maximum Received Power rating of -3.866 dBm at 8 dBm CW Laser power, while for the minimum Received Power has -20.105 dBm at CW Laser power of -8 dBm. System performance is strongly influenced by power changes in the CW Laser, as well as the use of high frequencies or low wavelengths. Keywords: DWDM, BER, EDFA, Q-Factor.
