AB The problem of four wave mixing (FWM) has become the principle focus for communication Engineers in designing a wavelength division multiplexing (WDM) system which is generated due to the optical nonlinear effect of fiber in multichannel systems. It has been observed through simulations results of different techniques that FWM effect becomes maximum when the fiber dispersion level approaches to zero. In this paper we have investigated the hybrid modulations for suppressing the FWM effect in 2.5Gbps system on OptiSystem Software and proposed the three hybrid modulators schemes depending upon the level of FWM suppression considering the results of eye diagram at different power levels. During simulation we use the default values of the parameters of modulators employed. Three schemes, High level reduction, Low level reduction and Intermediate level reduction have been implemented using combination of different modulators in this paper and their simulation results show that the Intermediate level reduction technique (Hybrid Tripely Technique) is comparatively the better one.
