EDFA pump laser control method and device |
abstract |
The invention relates to the technical field of optical communication, in particular to an EDFA pump laser control method and a device, wherein the method mainly comprises the following steps: executing a current real-time control calculation module to obtain a current DAC _ Calc value; executing a DAC normalization module and a pulse width calculation module to obtain a current DAC value and Duty _ PWM; outputting the DAC value to a digital-to-analog converter, and outputting the Duty _ PWM to a PWM generator; the digital-to-analog converter outputs the required current driving voltage and drives the pump laser through the driving circuit; and circularly executing the circular execution step in real time. The invention can solve the problem of stability of the EDFA caused by the threshold current of the pump laser, and ensure that the DWDM optical transmission network has better performance. |
