我们使用关联OTDR测量了100公里光纤链路的延迟。通过将探测信号速率提高到10Gbit/S,使用色散补偿光栅,并将接收器时基耦合到外部PPS信号,实现了对以前结果的改进。
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.
