Description

technical field [0001] The present invention relates to the technical field of photoelectric signal processing, in particular to the technical field of control modes of optical fiber amplifiers, and specifically refers to a system, method, device, processor and computer-readable storage medium for pulse energy control of optical fiber amplifiers. Background technique [0002] The usual fiber amplifier EDFA / YDFA generally has three control modes: [0003] 1. Automatic power control mode (APC) [0004] APC: Auto Power Control, automatic power control or constant power mode, means that no matter how the input power Pi changes, this mode adjusts the gain of the amplifier in real time by detecting the output power Po to ensure that the output power Po is constant. Such as figure 1 As shown, Po=Pi+Gain. [0005] For example, when the input power Pi decreases due to line attenuation or system aging, and the control system detects that Po decreases, the system will automatically ...

AI Technical Summary

Problems solved by technology

Due to the narrow pulse width and low duty cycle of this type of signal, the conventional method cannot accurately detect the output power and cannot realize the APC mode, so it has been more helpless to use the ACC mode to control

[0017]ACC mode can only realize the amplification of the amplifier, but in use, due to the change of input power, the change of ambient temperature, the attenuation of the line, and the aging of the device will bring The output power of the system changes slowly or quickly, and the ACC mode itself cannot adjust the change. This mode is actually an open-loop mode for the amplifier optics, which makes the comparison of pulse amplification accuracy requirements in the industry. High systems do not have good fiber amplifiers to use
