N2 - We propose and experimentally demonstrate a stable wideband signal dissemination system based on high-accuracy optical transfer delay measurement. In the proposed system, the absolute time delay of the fiber link is accurately measured based on phase-derived ranging, and then the fiber link is actively stabilized for stable wideband signal dissemination. As a demonstration, a wideband signal with a bandwidth of 4 GHz and a center frequency of 16 GHz is transmitted over a 1-km-long single-mode fiber, and the peak-to-peak time jitter is as small as 31.2 fs. The proposed system provides a high stability and a unique capability of absolute time delay measurement, which is promising to be widely used in distributed coherent detection systems.
