That interesting because in most metrology clock applications, phase noise is not a concern, rather long term drift. Here they are going to the difficulty to maintain low phase noise (jitter).
- smp1234 10y agoI guess phase noise could result in broadening of the laser line width, which would increase the averaging time needed to achieve the desired precision.
- acqq 10y agoI compare it with what I played with personally: NTP. The drift is covered here by the very clock technology, the jitter of the line, just like in NTP, is why the cables are specially tuned. Both are needed. This is just my guess, however, and if somebody knows more, please write!
