Abstract
The invention relates to a transmitting station (SS), and intermediate repeater (ZV1 to ZVn) and a receiving station (ES) for an optical communications-transmitting system for transmitting useful data of a high bit rate by means of at least one optically narrow-band carrier signal, and for transmitting additional data, for example service information, of a low bit rate. In order to operate the communications-transmitting system with the lowest possible outlay, an optically wide-band carrier signal, for example from a super-luminescence diode, which is located in the wavelength range of the narrow-band optical carrier signal, is used for transmitting the additional data. Both the optically narrow-band carrier signal of the useful data and the optically wide-band carrier signal of the additional data are located within the amplifying range of an optical fiber amplifier disposed in the intermediate repeater (ZV1 to ZVn). Both carrier signals can be selected with simple means.
