Abstract

Very high time resolution of pulse timing drift sensor for long fiber skew monitor is demonstrated by using the 10-cc compact module which is used the cross-correlation and differential detection technique. The signal pulse timing drift value and direction are correctly measured even when the signal intensity is fluctuated. The sub-picosecond pulse timing drift through the long fiber delay line is detected by this module.
