Abstract
Chromatic Dispersion Compensation (CDC) using Fiber Bragg Grating (FBG) techniques in Dense Wavelength Division Multiplexing (DWDM) system is presented in this article. Pulse broadening effects on the transmitted signal can be limited by Dispersion Compensation (DC) mechanisms. To overcome this problem and improve the system performance, a suggested system for 10 Gbps using Chirped Fiber Bragg Grating (CFBG) as a dispersion compensator, Non-Return-to-Zero (NRZ) modulation format and an Erbium Doped fiber Amplifier (EDFA) on a Single Mode Fiber (SMF) is designed. The result shows that, with using CFBG grating length of 90 mm, SMF length of 30 Km, input power of 15 dBm and attenuation coefficient 0.1 dB/Km, the Quality-Factor (QF) is 39.9373 dB. However, increasing SMF length to 100 Km, the QF is 12.173 dB. Thus, Results show that this model is more efficient in terms of QF, Bit Error Rate (BER) and eye diagrams related to other published papers which can be useful in many applications in telecommunication system like Sensor Networks, Remote Radar Networks, Tele-spectroscopic process control network, and many more networks.
