Improvement of accuracy for measurement of 100-km fibre latency with Correlation OTDR
arXiv:2011.10325 · doi:10.1049/cp.2019.0901
Abstract
We measured the latency of a 100 km fibre link using a Correlation OTDR. Improvements over previous results were achieved by increasing the probe signal rate to 10 Gbit/s, using dispersion compensation gratings, and coupling the receiver time base to an external PPS signal.
