A Nonlinear Optical Pulse through a Fiber Chain with NormalAverage Group Velocity Dispersion
A nonlinear RZ optical pulse through a fiber chain with average GVD in the normal dispersion is numerically researched.The results show that the nonlinear optical pulse with the input pulse width 20 ps
repetitive frequency 7.4 GHz can propagate over 1 000 km even if the fiber chain has average GVD in the normal dispersion. But enhancing input power can not lengthen transmission distance.
