Aiming at the demand of local distributed time synchronization, a short range distributed time synchronization scheme based on the combination of optical fiber and visible light is proposed. Combining the advantages of high accuracy of optical fiber time synchronization and high flexibility of visible light time synchronization, a corresponding time synchronization terminal is designed and distributed experiments are carried out. The experimental results show that when the length of the fiber link is 3 km, the 3σ clock difference between slave and the main end is better than 448 ps, the second stability of the time synchronization is better than 150 ps, and the 10 000 second stability is better than 4 ps. When the length of the optical fiber link is 1 km and the visible light link length is 5 m, the 3σ clock difference between the slave end of the visible light time synchronization and the primary end of the optical fiber time synchronization is better than 1.8 ns, the time synchronization stability is better than 400 ps in seconds, and the time synchronization stability is better than 15 ps in 10 000 seconds.
