Embodiment Construction
[0044] In order to solve the above technical problems and achieve the purpose of automatically controlling the output power of the laser driver and optimizing the extinction ratio of the output light pulse, the present invention proposes the following method:
[0045] The monitoring current signal generated by the photodetector (photodiode) is converted into a corresponding monitoring voltage signal using a transconductance amplifier. In the burst mode optical transmitter system, add peak value extraction, valley value extraction and mean value extraction and corresponding holding circuits.
[0046] According to the control of the burst enable signal, when entering the burst enable period, the peak value, valley value and average value of the monitoring voltage obtained by the above three extraction circuits respectively; when entering the burst disable period, the three voltage values Storage remains.
[0047] When a new burst enable cycle starts, the reset signal generation...
