Additional optical signals with wavelengths of (» A1 , ..., » Az ), different from the wavelengths of useful optical signals with wavelengths of (» 1 , ..., » n ), are modified in a processing unit (PU) and then introduced into a telecommunication optical fibre (OF) via a second photocoupler (Ph2). Correctness of transmission of all optical signals in the telecommunication optical fibre (OF) is controlled by an analysis unit (AU). The results of these analyses are sent to a control unit (CU) via a comparator (C). Electrical signals generated in the control unit (CU) set the parameters of a restorer (R) in a way ensuring emergence of all additional optical signals with wavelengths of (» A1 , ... , X Az ) at its outputs, without distortion of the data transmitted using them. |
