STW-FT Series Optical Fiber Time and Frequency Transmission/Measurement Products
  The STW-FT series of optical fiber time and frequency transmission/ measurement equipment can achieve high stability transmission of the signal to be transmitted by actively detecting and compensating for the phase fluctuations introduced during the optical fiber transmission process. The frequency transmission stability of this system is at least two orders of magnitude higher than that of uncompensated optical fiber transmission, and about three orders of magnitude higher than frequency synchronization achieved by relying on GPS. It is particularly suitable for the remote distribution of high-stability atomic clock frequency signals and is an ideal choice for building distributed clock ensemble systems and distributing high-precision frequency standard signals.
