Abstract

The relationship between the time deviation introduced by dispersion and the location of remote stations in ring fiber network is studied in this paper. A method is proposed that the location of remote stations in ring fiber network can be sensed by the remote stations, and compensation can be calculated to adjust the convergence position of the recovered 1PPS signal. We demonstrate a time dissemination experiment via 100km ring fiber network to study the correction method of asymmetry deviation introduced by dispersion. After the calibration of the deviation, time synchronization accuracy of 100ps is realized. Synchronized remote stations can be accessed at anywhere in the ring fiber network.
