摘要

文章采用非线性系统的守恒律和位力定理对光传输系统中损耗对载波光信号传输的影响进行了研究。研究表明

在普通光纤与色散补偿光纤的交界处

孤波的幅度有所降低

但其形状保持不变;光孤子通过放大器后其幅度得到放大

其形状将自动得到恢复。该信号可以高保真地在光纤中传输

具有理想信息载体的特性。

Abstract

The influences of losses in optical transmission systems on carrier optical signal propagation are studied by using the conservation law and the viral theorem of the nonlinear system in this paper.The results indicate that the soliton amplitude slightly decreases in the border between the Single-Mode Fiber（SMF） and the Dispersion Compensation Fiber（DCF）

but and its shape remains unchanged

while its signal amplitude is amplified when it passes an amplifier and its shape automatically restored.Such a signal can be transmitted with high fidelity and has the haracteristics of an ideal information carrier.
