Method and system for the transmission of signal packets over an optical line.

摘要

The invention relates to a method and a system for transmission of digital signals by packets between at least two stations (S1, S2) for transmission and/or reception, which are connected by optical fibres (3), and in which at least one of the two stations is equipped with transmission means (100) comprising an optical transmitter (106) and means (150) of modulating the optical signal of the transmitter which comprise means (105) of generating a characteristic modulation signal suitable for modulating the optical signal in the interval separating two packets, the transmitted signal being a composite signal and in which the other station is equipped with receiving means (200) comprising an optical detector (201) and means (250) of demodulating the composite signal detected, and which are suitable for distinguishing the digital packet signals of the characteristic signal. Application to the transmission of digital signals by packets.
