Yang Bin1, Zhong Weiping2. Influences of loss in nonlinear optical communication system on optical signal propagation[J]. 2007,(4):19-21. DOI: 10.13756/j.gtxyj.2007.04.006.
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.
