Performance Comparison of FBG as Dispersion Compensator with Different Frequency Chirp in an Optical Fiber Link

Abstract

Abstract

Recent day’s optical communication is a most popular technique for transmission of data. We share most of our data through optical network, but the main huddle in performance is dispersion. However, the compensation of dispersion by Dispersion Compensating Fiber (DCF) and Fiber Bragg Grating (FBG) can boost significantly the system. Our proposed work investigates and analyzes the performance of optical transmission system at 1550 nm using FBG as dispersion compensator. The FBGs with several types of frequency chirp is modeled in this project. It was proven that different frequency chirp profile could reduce the side lobes. Additionally, each profile also has better bandwidth and maximum reflectivity than others. Link has been simulated in OptiSystem which is efficient optical communication software.
