A latest scheme is analyzed on wideband dispersion-compensation (WBDC) based on the new format of fiber bragg grating known as apodized chirped fiber Bragg grating known as ACFBG. As pulse spreading became one of the most restricted factors to implement a optimized optical propagation system. It became necessary to remove the dispersive parameter from the transmitted signal. Hence, apodized gratings are the best options to maintain the reflectivity and to improve side-lobe suppression. Gaussian function at gauss parameter 0.2 and tanh function at parameter 0.5 are approached as apodized functions of fiber Bragg grating. This proposed model is simulated on the basis of various data rates i.e 20Gbps and 40 gbps, at particular input power and at diverse fbg length. Optisystem 14.2 software is used to simulate the performance of the system.
