AbstractThe joint transfer of frequency and one pulse-per-second time signals based on dense wavelength division multiplexing technology is demonstrated over a compensated cascaded fiber link of 230 km, consisting of two stages of fiber links with lengths of 150 km and 80 k m. A bi-directional erbium-doped fiber amplifier is inserted in the center of 150 km fiber link to compensate for significant optical attenuation. After every stage has achieved the steady state by optical compensation, the Allan deviation of frequency signal of the cascaded system is 3.1*10~(-14) at 1 s and 6.3 * 10~(-18) at 10~4s respectively; the time deviation of time signal is less than 3.5 ps at an averaging time of 10~2 s to 10~4 s. Further, it is verified that the stability of the cascaded link is the standard deviation of the stabilities of the two stages links for both frequency and time signals. After calibration, time synchronization is also realized and the accuracy is within 90 ps.

Other Abstract基于波分复用技术,通过级联方式在230 km光纤链路中实现了频率和时间的同传。该级联系统包含了150 km和80 km两级链路系统,其中为了补偿150 km光纤链路中的损耗,在链路中间放置了一个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,整个级联系统的频率稳定度为3.1*10~(14)(平均时间1 S时)和6.3*10~(18)(平均时间10~4s时),时间稳定度为3.5pS(平均时间10~2~10~4s时)。实验结果也证明,不管是对频率信号还是时间信号,都满足误差理论,整个系统的稳定
