Abstract

As a multiplexing technique commonly used in optical fiber communication networks, dense wavelength division multiplexing (DWDM) can transmit signals with different wavelengths in the same channel. The small channel spacing makes it suitable for use on long distance transmissions, and can streamline channel usage. Behind its advantages, DWDM has one of the weaknesses known as nonlinear effects, which is caused by the nonlinearity of the fiber optic medium. One of the types of nonlinear effects is four wave mixing (FWM). In this study a study was conducted to minimize nonlinear effects using 3 schemes, namely MZ Modulator, PM-AM, PM-AM-MZ Modulator. The channel spacing used is 50 GHz with a 10 Gbps bitrate. Of all the variations of the scenario in the MZ Modulator and PM-AM scheme, it results in Q-Factor and BER values that do not match the standards of 6 and 10 respectively. On the other hand, PM-AM-MZ Modulator schemes produce Q-Factor and BER values that conform to the standard. -9 Keywords: DWDM, FWM, MZ Modulator, PM-AM, PM-AM-MZ Modulator, Q-Factor, dan BER.
