摘要

光纤Bragg光栅(FBG)是限制色散的关键技术之一，本文采用光纤光栅这一广泛应用的器件，利用线性啁啾和Tanh离化函数对色散进行补偿，并在系统电气部分嵌入低通高斯滤波器，以提高系统性能的q因子和眼图。然后研究了使用低通高斯滤波器和不使用低通高斯滤波器时系统的q因子。使用光纤光栅时，系统30km长度的q因子为20.2748，使用光纤光栅和低通高斯滤波器后，q因子达到26.9039;我们意识到使用光纤光栅和低通高斯滤波器作为色散补偿元件可以获得更好的系统性能。用不同长度的光纤对系统进行了分析，并用optisystemver15软件对系统进行了评价。

Dispersion Compensation by Using FBG and Low Pass Gaussian Filter

Fiber Bragg Gratings (FBG) is one of the essential techniques that applied for limiting the dispersion, in this paper we use FBG which is widely used component to compensate dispersion with linear chirp and Tanh apodization function, and additionally we embedded low pass Gaussian filter in the electrical part of the system to improve the Q-factor of the performance and eye diagram. The Q-factor of the system is then investigated with and without the Low pass Gaussian filter. The Q-factor of 30km length of the system with FBG is 20.2748, and by using FBG and Low Pass Gaussian Filter, the Q-factor managed to reach 26.9039; We realize that using FBG and Low Pass Gaussian filter as dispersion compensation element gives a better system performance. The system is analyzed with various fiber lengths and evaluated by using optisystem ver15.
