		abstract={ABSTRACT     Dense Wavelength Division Multiplexing (DWDM) is a transmission techique that using light with different wavelength which afterward done multiplexing process so transmitted trough fiber optic. On DWDM transmission systems there are nonlinier effect one of them is Four Wave Mixing (FWM). FWM is a non linier effect that will affect network system performance of fiber optic communication with the addition of signals that transmitted on fiber optic. In this research DWDM system design are using three scenarios, such as EDFA-ROA, ROA-EDFA and ROA-ROA using Optisystem 15 to reduce the non linier effect of FWM that found on fiber optic communication system using DWDM system design. This design is using 16 channels with 1.6 channel spacing and 100 km link length. On this research the power variations in the laser were 0, 2, 4, 6, 8, and 10 dbm. Based on the results of testing has been done on Dense Wavelength Divison Multiplexing (DWDM), of the three scenarios that used ini this simulation there is one scenario that has the best result like ROA-ROA with value on the input power side having BER value 8.23E-07 with input power 8 dBm and Q-Factor 4.865933 with input power 10 dBm, for the value on the canal side has BER value 2.00E-06 on channel 10  and Q-Factor 4.74117 on channel 16.
