Design and Analysis of Ultra High Speed 16 Channel Cascaded EDF A-DWDM Network with Post Dispersion Compensations Using Optimization of Fiber Bragg Grating

This article introduces an optimization of optical network system using the residual power of doped-fiber amplifier (EDFA) and optimized dispersion management by fiber bragg grating. If transmitted signal speed is increased to 8 * 5 Gbps, the dispersion is caused due to several reasons and pulse becomes indistinguishable at the destination. Its purpose is to use DCF in network to design and analyze the dispersion compensation system and here FBG used as a post-dispersion compensator. The main purpose is to achieve a constant gain over the entire transmission spectrum of the 16 narrow gap channels to match the amplitude gain of the DWDM system. The method was simulated using Optisystem 16.1 software package to achieve the uniformity of EDFA gain by changing the EDFA pump source power and system CW power. The planner gain is 41±0.4 decibels in the wavelength range from 1548 to 1556 nm, the NF close to 7 dB, the flattened EDFA gain at fiber length close to 8m, the frequency interval between channels is 0.5nm and dispersion significantly managed.
