Abstract
A system for transmission on an optical link by modulating an optical carrier suitable for video-communication cable networks, includes devices for increasing the modulation of the optical carrier, such as increasing the intensity modulation. The system is particularly suited for the case in which a high input optical power is coupled into the optical link. Also, the modulation can be increased from a null value if the modulation is other than intensity modulation, in order to prevent or to reduce phenomena degrading transmission quality associated with the Brillouin effect.
