Abstract

A method for measuring a packet delay in an optical node of a synchronous network, the method comprising : - splitting the input optical signal, - shifting in time the second optical signal of one timeslot the method further comprising, for each of the first optical signal and second optical signal: - Detecting the packet label and generating a corresponding pulse (28, 30), And the method further comprising: - generate a synchronization pulse (35) during an overlap between the first electronic pulse and the second electronic pulse, - Measuring a wavelength average delay time (38), - Generating a synchronized trigger signal (39) as a function of the wavelength average delay time, and - Comparing the synchronized trigger signal with the electronic detection pulse to determine the packet delay between the synchronized trigger signal and the electronic detection pulse.
