摘要：
A system is provided for determining a propagation time of an optical signal between two devices in an optical transmission network. The first device is designed to determine the propagation time following the transmission of an optical measurement signal in a propagation direction towards a second device using an optical link while passing through an intermediate device, which includes at least one amplifier and one chromatic-dispersion compensation module that introduces a delay, and following the reception an optical return signal from the second device using the same optical link in a direction opposite to the propagation direction. The measurement system is configured to extract the return signal output by the intermediate device; regenerate the extracted return signal; feed the regenerated signal into the optical link, at the input of the intermediate device; and obtain a return signal-reception time while taking account the delay introduced by said compensation module.
