Method and device for controlling the peak power of a laser transmitter in discontinuous optical transmission systems.

摘要

The device controls the peak power by acting on the threshold current of the transmitter. A sample and hold circuit (SH) samples the current supplied by the monitoring detector associated with the transmitter, and a processing unit (MP) obtains an actual value of the peak power as an average of the values associated with a certain number of samples of the monitoring current and, in case of divergence between the actual value and a desired value, obtains a correct value for the threshold current.
