中文摘要:
通过级联方式在京沪光纤骨干网中实现了430 km的高精度频率传递。该级联系统包含了280 km和150 km两级系统,同时为了补偿光纤损耗,在两级链路中采用了低噪声高对称的双向掺铒光纤放大器。当每一级传递系统通过光学补偿方式达到稳定后,整个级联系统引入的频率不稳定度为在1 s处1.02*10~(-13)和在10~4 s处8.24*10~(17),实验结果验证了级联系统的实际结果与两级系统计算结果之间符合误差理论。

英文摘要:
High precise frequency transfer is realized in partial Beijing-Shanghai optical fiber backbone network of 430 km using the cascaded method. The entire cascaded system is comprised of two stages with fiber links of 280 km and 150 km, respectively. To keep high symmetry and low noise, specific bi-directional Erbium-doped fiber amplifiers are used to compensate the large optical attenuation of each fiber link. When the whole system achieves stable status by optical compensation method, the stabilities of 1. 02 * 10~(-13) at 1 s and 8. 24 * 10-17 at 104 s are obtained. Experimental results verify that the actual results of the cascaded system are in accord with the error theoretical ones calculated from the results of two stages.
