Performance Analysis of WDM Link Using Different DCF Techniques
Fiber-optic dispersion and its effect on optical transmission system are analyzed. The most commonly used Dispersion Compensation Fiber (DCF) technology is studied in this paper. Three schemes (pre-compensation, post-compensation, mix-compensation of dispersion compensation) of dispersion compensation with DCF are proposed. In this paper, the authors propose three DCF compensation scheme, pre-compensation, under-compensation and mix compensation scheme. Simulation studies show that mix compensation scheme is the best. It can greatly reduce the influences of the fiber nonlinearity and increase the transmission distance greatly.
