Abstract
An optical communication line having a first control unit; an optical transmission fibre connected to the first control unit for transmitting an optical signal; and an optical amplification unit inserted along the optical transmission fibre for amplifying the optical signal. The optical amplification unit has an optical amplifier for amplifying the optical signal, a magneto-optical attenuator connected to the optical amplifier, and a control device for regulating the light transmissivity of the magneto-optical attenuator, wherein the first control unit has a magneto-optical attenuator and a control device for regulating the light transmissivity of the magneto-optical attenuator so as to superimpose service informations on the optical signal. In the optical amplification unit, the control device is suitable to regulate the light transmissivity of the magneto-optical attenuator so as to superimpose service informations on the optical signal.
