Abstract :
In this paper, high-bit-rate transmission systems with a chirped fiber grating dispersion compensator are investigated and simulated by solving nonlinear Schrödinger equations. Due to the effect of non-ideal dispersion and reflection characteristics of traditional apodized linearly chirped fiber gratings, the degradation of eye diagrams is very serious in 40Gb/s NRZ-transmission systems. Then, a dispersion compensator based on chirped fiber grating is designed by the layer peeling algorithm. After 40Gbit/s transmission over 800Km of standard single-mode fibers, the eye diagram is still clear, and the power penalty is only 0.45dB for this dispersion compensator. Simulation results show that: the chirped fiber grating designed by the layer peeling algorithm has excellent performances as the dispersion compensator in high-bit-rate transmission systems.
