摘要
在深入分析量子密钥分配(QKD)系统的同步需求和电力架空光缆中信号延时变化因素之后,对电力架空光缆中同缆不同芯同步技术和同缆同芯同步两种同步技术展开研究。最后结合实际要求提出了具体设计方法,以满足电力环境下的QKD系统实际运行需求。
After thoroughly analyzing synchronization requirements of QKD system and factors of delay varia- tion in the electric aerial optical cable, in the paper it is studied for two synchronization technologies over elec- tric aerial optical cable, which is using another core as synchronizing channel, the other is transmitting the syn- chronization signal and quantum signal in the same core. Specific design requirements of these two synchro- nization technologies are proposed to satisfy the operation demands of QKD systems.
