在现代工业中，光纤传输和通信是不断发展和支持更多挑战的技术。光纤的三个特性是色散、吸收和散射，它们会引起衰减，也会降低传输功率。为了克服这些损失，提高光纤的可靠性，引入了许多先进技术。利用仿真软件OPTSIM对光纤布拉格光栅和光学相位共轭两种色散补偿技术进行了研究。我们还利用孟加拉国拉吉沙希工程技术大学电信实验室的B4530训练器对接收信号的时延随频率的变化进行了分析，证明了随着发射信号频率的增加，接收信号的时延即色散减小。
In the modern day industries, Fiber optic transmission and communication are technologies that are constantly growing and support more challenges. Three properties of optical fibers are dispersion, absorption and scattering which cause attenuation and also decreased in transmitted power. To combat these losses and improve the reliability of fibers introduced many advanced technologies. Here two compensation techniques such as Fiber Bragg Grating and Optical Phase Conjugation are discussed with the help of simulation software “OPTSIM” to compensate dispersion. We have also analyzed the time delay of the received signal with variation of frequency by using B4530 trainer in the “Telecommunication Lab, Rajshahi University of Engineering & Technology, Bangladesh” and proved that when frequency of the transmitted signal increases then time delay i.e. dispersion of the received signal decreases.
