Performance Comparison of Dispersion Compensation at 10 Gbit/s for Various Optical Fiber Links

The performance dependence of 10 Gbit/s single channel transmission system on the optimal residual dispersion and the fiber input optical power is simulated and compared with 400-km SMF and various kinds of NZ-DSFs. We have shown that optimal residual dispersion depends on the type of the optical fiber and optical power launched into it. The optimal residual dispersion region for 10 Gbit/s DWDM system with SMF and NZ-DSFs is deduced at last.
