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.

基于光纤布拉格光栅的密集波分复用中的高质量因数和色散补偿

摘要

本文介绍了在密集波分复用（DWDM）系统中使用光纤布拉格光栅（FBG）技术的色散补偿（CDC）。脉冲展宽对传输信号的影响可以通过色散补偿（DC）机制来限制。为克服此问题并提高系统性能，建议使用for光纤布拉格光栅（CFBG）作为色散补偿器，非归零（NRZ）调制格式和掺Do光纤放大器（EDFA）的10 Gbps系统设计在单模光纤（SMF）上。结果表明，使用90 mm的CFBG光栅长度，30 Km的SMF长度，15 dBm的输入功率和0.1 dB / Km的衰减系数，质量因子（QF）为39.9373 dB。但是，将SMF长度增加到100 Km，QF为12.173 dB。从而，
