Abstract

This system for transmitting, over an optical link, a signal referred to as auxiliary with respect to a traffic signal transmitted simultaneously over this link, for optical link comprising at least one rig itself comprising means (1) of optical amplification of incident optical signals, comprises essentially, for the transmission of an auxiliary signal by the said rig, means (2, 4, 5, 6) of modulating the gain of the optical amplification means of this rig by the said auxiliary signal. <IMAGE>
