【摘要】 在高速光纤通信系统、特别是单信道速率为 10 Gb/s 以上的系统中,色散补偿是提高信噪比(SNR)、改善系统性能的必要手段。从实用的角度,提出了一种适用于单通道 40 Gb/s、80 个通道的高速密集波分复用(DWDM)系统的色散补偿方案,即采用全拉曼放大,将色散补偿光纤进行合理的配置,达到色散补偿的目的。仿真验证表明,该方案可实现在普通单模光纤中跨距500 km的传输。更多还原

【Abstract】 In the high-speed optical-fiber communication system,chromatic dispersion compensation is a necessary way to improve signal-to-noise ratio(SNR) and the performance of the system.In this paper,we proposed a practical method for 3.2 Tbit/s(40 Gbit/s 40 Gbit/s/channel×80 channel) transmission system.It can be achieved by combining two DCFs in the DCF module(one with high and one with a low RDS) and all distributed Raman amplification.The primary simulation and the effective result were obtained.This is valuable and referable for the realization of the high-speed optical-fiber communication system.更多还原
