Abstract

AbstractNowadays, optical communication is a popular technique to transmit the data. In daily life, we share our useful data by using optical network but dispersion is the main performance limiting factor. However, the compensation of dispersion by dispersion compensating fiber (DCF) and fiber Bragg grating (FBG) can boost the system significantly. This 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 apodization were modeled in this study. It was proven that apodization profile could reduce the sidelobes. In addition, each profile also has the bandwidth and the maximum reflectivity better than others. Link has been simulated in efficient optical communication software called Opti-system.Keywords: Bit error rate, DC, dispersion compensating fiber, eye diagram, fiber Bragg grating, optical power meter, Q-factor, SMF, VAS, WDM systemCite this ArticleRaghavendra Patidar, Hitesh Joshi.
