We present a new design of femtosecond timing system. In the system, RF signal and timing events are transmitted synchronously in one single optical fiber with very high accuracy. Based on the theory of Michelson's interferometer, phase drift is detected with accuracy at femtoseconds. And phase compensation is accomplished in transmitter with two approaches afterwards. Moreover, the traditional event timing system is integrated into the new system to further reduce the jitter of timing triggers. The system could be applied in synchrotron light sources, free electron lasers and colliders, where distribution of highly stable timing information is required. The physics design, simulation analysis and preliminary results are demonstrated in the paper.
