Abstract :
TWOTFT has been studied and implemented according to the similar principles to those of TWSTFT. We initially constructed the experiment system for TWOTFT and done some experiments such as time and frequency transfer through the laboratory optical fiber and the real optical fiber links including the real link with 109 km length at NIM. We can get the time stability of less than 6 ps/s and 0.9 ps/100s, and the standard uncertainty of less than 200 ps for time transfer.
