Abstract
The transmission device comprises at least one laser transmitter ( ) which emits light ( ) as a function of binary data signals ( ) which are to be transmitted, and a monitor receiver ( ) which receives part of the emitted light ( ) and converts it to a monitor current (I ). A control circuit regulates the mean optical output power (P ) of the laser transmitter to a constant value on the basis of a DC prescribed value (VDC) by evaluating the monitor current (I ), the prescribed value (VDC) being obtained by tuning and being permanently stored in a read only memory (FSP) in the course of the tuning.
