Abstract
We demonstrate a compact signal transmission delay measurement system in optical fibers. The frequency of a microwave signal is locked to the signal transmission delay which can be obtained in frequency domain. With a frequency-scanning ambiguity resolving system, the signal transmission delay can be precisely determined. The system delay fluctuation is monitored in real-time and subtracted from the measurement result. This method achieves sub-picosecond uncertainty.
