The research on 10Gbps optical communication dispersion compensation systems without electric regenerator

Dispersion is one of main factors to limit the development of the optical fiber communication systems to be long-distance, high-speed and large capacity. In this paper, 2500km-10Gbps optical communication dispersion compensation systems based on FBG without electric regenerator are designed. Four schemes based on fiber Bragg grating (FBG) are realized through simulation: pre-compensation, post-compensation and two kinds of symmetrical compensation. The results demonstrate that: compared with pre-post compensation and two kinds of symmetrical compensation, post-compensation based on FBG shows the best performance. On the condition of full compensation, as the peak power of the input pulse grows, FBG post-compensation performs generally better than DCF post-compensation for the 10Gbps optical communication transmission systems.
