Suppression of FWM Effects by using Cost Effective Combined DCF and FBG Module


Objectives: The main aim of this research paper is suppression of Four Wave Mixing effect using cost effective combined dispersion compensation fiber and fiber brag grating module. Methods/Statistical Analysis: Four-Wave Mixing (FWM) nonlinearity is observed in this work along with its suppression technique. At high powers, maximum FWM power can be seen and at low power very less nonlinearity. Several FWM degradation schemes proposed so far but they limited in terms of performance and are very expensive such as phase conjugator. Findings: In current work a cost effective FBG in uniform chirping and tanhapodization is used to suppress FWM. Also comparison has been done with single tanhapodized FBG, conventional FBG and combined DCF and FBG module. Application/Improvement: It is realized that, in coming future, use of Broadband amplifier like HOA can be used for the further analysis of this system for C+L band to effect of amplification and dispersion. And work can be further extended to no. of users increased and data rate.
Keywords: Dispersion Compensation Fiber (DCF), Fiber Brag Grating (FBG), Four-Wave Mixing (FWM)
