Inhalt:
By means of C-OTDR (Correlation - Optical Time Domain Reflectometry), we measured the latency of 100 km fiber with an accuracy of a few picoseconds. Based on iterating 49 measurements, we calculated a standard deviation of 12 ps between the round-trip latency values. To verify the reflection measurements, we used a single pass setup without reflector, which showed a maximum difference of only 11 ps.
