Abstract
The transmission device comprises at least one laser transmitter (1) which emits light (2) as a function of binary data signals (24) which are to be transmitted, and a monitor receiver (4) which receives part of the emitted light (2) and converts it to a monitor current (I.sub.MON). A control circuit regulates the mean optical output power (P.sub.opt) of the laser transmitter to a constant value on the basis of a DC prescribed value (VDC) by evaluating the monitor current (I.sub.MON), the prescribed value (VDC) being obtained by tuning and being permanently stored in a read only memory (FSP) in the course of the tuning.
