Mao Yingchao, Sun Fengjie, Ma Yonghong. Dispersion compensation of 10 Gbit/s unrepeatered fiber-optic transmission systems[J]. 2007,(5):18-20. DOI: 10.13756/j.gtxyj.2007.05.008.
文章分别研究了色散补偿光纤(DCF)、啁啾光纤光栅(CFG)两种色散补偿方案。通过数值仿真分别实现了10 Gbit/s 198 km和220 km G.652光纤的无中继传输。仿真实验证实
采用CFG补偿可使传输距离增加约10%
并且当误码率为10-12时
无误码传输的功率代价仅为1.6 dB。
Abstract
There are many dispersion compensation technologies used in fiber-optic communications.The paper investigates two types of dispersion compensation schemes: Dispersion Compensation Fiber(DCF) and Chirped Fiber Grating(CFG) and realizes unrepeatered transmissions over 198 km and 220 km G.652 fibers respectively by numerical simulation.The simulations prove that the transmission distance can be improved by about 10% by using CFG dispersion compensation and when BER is 10-12
the power penalty for errorless transmission induced by the dispersion compensation after 220 km is only 1.6 dB.
