Optical transmitter for an optical communication system in connection with a radio system |
摘要 |
A prior art optical transmitter for an optical communication system having a radio system connected thereto comprises a DFB laser, an optical modulator, a signal source, and an optical filter. This optical transmitter transmits light which is not modulated by an intelligence signal. It is disadvantageous in that the optical filter and the DFB laser must be matched. An embodiment of the optical transmitter according to the invention comprises a light source (1), an optical modulator (2), and a control unit (3) which controls the light source (1) and the modulator (2) in such a way that the light emerging at the output (5) of the modulator (2) is modulated with an intelligence signal.
