Dissemination stability and phase noise specification of fiber-cascaded RF frequency dissemination
arXiv:1504.04994
Abstract
Over the past decade, fiber based frequency dissemination has achieved significant progresses in following aspects. To study the dissemination stability and phase noise specifications of the fiber-cascaded RF frequency dissemination system, we perform a lab-top experiment using three sets of RF modulated frequency dissemination systems. They are linked by 50 km + 50 km +45 km fiber spools. The dissemination stabilities of each segments and whole system are measured simultaneously. After that, the phase noise of each segment is also measured and the result shows that the phase noise spectrums of recovered frequency signal can be optimized via narrow band phase lock loop.
