The object of this study is to enhance dispersion compensation to maximize transmission bit rate in single mode silica fibers. This is achieved through a proposed model that starts with finding the optimal operating parameters for single mode silica fibers. These optimal operating parameters lead to near zero dispersion due to the nature of chromatic dispersion which mainly consists of material dispersion and waveguide dispersion. The proposed model employs soliton transmission technique, where the propagated pulse suffers the effects of nonlinearity self-phase modulation that shrinks the pulse in opposite effect to the chromatic dispersion. The balancing between chromatic dispersion and nonlinear effects will generate a soliton wave which propagates over a long transmission distance without any change. The proposed model consists of four identical stages cascaded apodized uniform fiber Bragg gratings and a soliton modulator. Different apodization functions are investigated. The maximum transmission bit rate per channel is 1.9932 Gbps of the proposed model with raised cosine apodized fiber Bragg grating and soliton at input signal wavelength = 1.70 µm, differential refractive index = 0.001, ambient temperature = 283 K, while at the same conditions the maximum transmission bit rate per channel of soliton only is 0.0452 Gbps.

这项研究的目的是增强色散补偿，以最大程度地提高单模石英光纤的传输比特率。这是通过提出的模型来实现的，该模型从寻找单模石英纤维的最佳工作参数开始。由于主要由材料色散和波导色散组成的色散特性，这些最佳工作参数导致色散接近于零。所提出的模型采用孤子传输技术，其中传播的脉冲受到非线性自相位调制的影响，该非线性自相位调制使脉冲收缩，而与色散相反。色散和非线性效应之间的平衡将产生孤子波，该孤子波在很长的传输距离内传播而没有任何变化。所提出的模型由四个相同的级联切趾切趾均匀光纤布拉格光栅和一个孤子调制器组成。研究了不同的切趾功能。在输入信号波长= 1.70 µm，微分折射率= 0.001，环境温度= 283 K的情况下，具有提升的余弦切趾光纤布拉格光栅和孤子的拟议模型，每通道的最大传输比特率为1.9932 Gbps，而在相同条件下的最大值孤子每通道的传输比特率仅为0.0452 Gbps。
