Optical networks offer higher data rates, and are fast and error free. However, non-linearity hinders them from being a perfect medium. Especially, FWM degrades the transmission characteristics of the optical systems and networks. FWM may result in crosstalk among optical channels. The paper presents a new approach to suppress the effect of four wave mixing using combination of hybrid modulator and optical rectangular filters. The performance of DWDM system and behaviour of four wave mixing is analysed. Hybrid modulator used here consists of Mach-Zehnder modulator followed by dual drive Mach-Zehnder and AM modulator. The system comprises of 8 channels each of data rate 5 Gbps. Also, comparative analysis is carried out using different fibres (Single mode fibre and ITU-T G.655). The maximum achieved Q-factor for SMF is 13.05 and 17.87 in case of ITU-T G.655.Dispersion compensating fibre is used to control dispersion. System is analysed for the length of 580 km in case of SMF and 530 km in case of ITU-T G.655.
