  We demonstrate a distributed atomic clocks network between Shanghai Institute
of Optics and fine Mechanics (SIOM) and Shanghai Institute of Measurement and
Test (SIMT). The frequency signals from three different clocks transfer in one
fiber link and four clocks can have comparison in two different labs.By
comparing the results of the comparison between the two labs, it was found that
the consistency of the frequency signal is on the order of lower than 1E-15.
And we also achieve consistency between two locations at the E-15 level of
frequency reporting. This scheme can achieve distributed time counting and
frequency dissemination of remote atomic clocks, which is a new exploration of
the future time keeping laboratory mode.
