Product Features
FDST series high precision fiber optic frequency transmission system can achieve high stability transmission of the signal to be transmitted by actively detecting and compensating for the phase fluctuations introduced during the fiber optic transmission of the signal to be transmitted. It is especially suitable for remote distribution of highly stable atomic clock frequency signals.
