Problems solved by technology
[0002] In the related art, the actual input and output shift circuit and sampling circuit of the Erbium Doped Fiber Application Amplifier (EDFA) have different response speeds to the power values of different incoming optical signals, and the passive devices have different response speeds to different wavelengths. There are also nonlinear effects in the gain flatness of the control circuit, and the response rate of the control circuit is not timely. Therefore, these comprehensive factors all affect the transient suppression effect in a wide gain and wide wavelength range.

The embodiment of the invention provides a transient suppression control method and device, equipment and a storage medium. The method comprises the steps of monitoring the power value change of an incident light signal and the power value change of an emergent light signal in real time; acquiring a feedforward compensation output signal value corresponding to the current light incident signal; when it is determined that the power value of the light incident light signal rises instantaneously, acquiring the power value of the current incident light signal and the power value of the current emergent light signal; determining a first expected output power value according to the power value of the current incident light signal; performing delay processing on the power value of the current emergent light signal to obtain a power value of a delayed emergent light signal; determining a first driving current value of a pump laser according to the first expected output power value, the power value of the delayed emergent light signal and a feedforward compensation output signal value corresponding to the current incident light signal; and driving the pump laser by the first driving currentvalue.
Description
technical field [0001] The present application relates to optical fiber amplifier control technology, in particular to a transient suppression control method, device, equipment and computer-readable storage medium. Background technique [0002] In the related art, the actual input and output shift circuit and sampling circuit of the Erbium Doped Fiber Application Amplifier (EDFA) have different response speeds to the power values of different incoming optical signals, and the passive devices have different response speeds to different wavelengths. There are also nonlinear effects in the gain flatness of the control circuit, and the response rate of the control circuit is not timely. Therefore, these comprehensive factors affect the transient suppression effect in a wide gain and wide wavelength range. Contents of the invention [0003] Embodiments of the present application are expected to provide a method and device for transient suppression control, an optical fiber am...
