We study a ring fiber network based multipoint time-frequency dissemination method with high precision. Further, a novel scheme that can realize self-perception for clock difference is proposed; the sensing measurement and compensation for the clock difference are located at remote stations. Time-frequency synchronization can be achieved between the remote stations and the local station. Subsequently, we perform a time-frequency dissemination experiment via a 100-km ring fiber network to study the correction method of asymmetry deviation introduced by dispersion. The multipoint time-frequency dissemination performance is verified under link temperature variation. The measured peak-to-peak value of synchronization error of time-frequency dissemination is smaller than 400 ps, and the root mean square error is smaller than 60 ps. The results show that the remote stations can be accessed anywhere in the ring fiber network.
